This was mass slaughter. 27 00:01:19,597 --> 00:01:21,682 [dramatic music] 28 00:01:21,757 --> 00:01:24,282 [narrator] the relics of the past hold secrets. 29 00:01:28,637 --> 00:01:33,642 Written in gold, stone, and blood. 30 00:01:34,637 --> 00:01:36,122 We can unlock them. 31 00:01:37,870 --> 00:01:42,162 These are the secrets of history's greatest treasures. 32 00:01:53,630 --> 00:01:57,042 Hadrian's wall, northern britain. 33 00:01:57,117 --> 00:02:01,362 Stretching from coast to coast, dividing the country in two. 34 00:02:03,277 --> 00:02:06,635 This was the hard border that separated roman britain 35 00:02:06,670 --> 00:02:08,875 From the rebellious iron age tribes 36 00:02:08,910 --> 00:02:10,842 Who roamed the lands to the north. 37 00:02:12,750 --> 00:02:14,555 [hannah-marie] hadrian's wall was exceptional. 38 00:02:14,590 --> 00:02:18,235 It is the only extensive fixed boundary in the empire. 39 00:02:18,270 --> 00:02:23,915 And it still stands today as an icon of roman power. 40 00:02:23,950 --> 00:02:27,595 [narrator] commissioned by emperor hadrian in 122 ad, 41 00:02:27,630 --> 00:02:29,675 The vast, heavily fortified wall 42 00:02:29,684 --> 00:02:34,075 Was completed in just six years. 43 00:02:34,110 --> 00:02:39,275 Once operational, 8,000 roman soldiers manned its defenses, 44 00:02:39,350 --> 00:02:41,042 Armed and ready to protect 45 00:02:41,117 --> 00:02:44,922 The empire's most northerly frontier at whatever cost. 46 00:02:46,724 --> 00:02:50,722 It's a message to both his citizens of rome and his army, 47 00:02:50,797 --> 00:02:53,515 But also everybody else outside looking in. 48 00:02:53,550 --> 00:02:57,275 That's the wall. That's the boundary. That's the edge. 49 00:02:57,310 --> 00:02:58,722 If you want to cross this, 50 00:02:58,797 --> 00:03:01,635 You have to have my permission to do so. 51 00:03:01,710 --> 00:03:04,395 [narrator] but now, a remarkable discovery 52 00:03:04,430 --> 00:03:06,515 In a battlefield in northern britain 53 00:03:06,590 --> 00:03:11,915 Is revealing the brutal lengths rome was prepared to go to. 54 00:03:11,950 --> 00:03:14,875 A weapon more accurate and more deadly 55 00:03:14,910 --> 00:03:18,235 Than any other in the ancient world. 56 00:03:18,270 --> 00:03:21,202 A terrifying killing machine designed 57 00:03:21,277 --> 00:03:23,275 To stamp out resistance 58 00:03:23,350 --> 00:03:26,762 And pave the way for rome's total domination. 59 00:03:29,710 --> 00:03:34,715 Burnswark, a remote outcrop in southern scotland. 60 00:03:34,750 --> 00:03:38,635 In 2015, an archeological investigation 61 00:03:38,670 --> 00:03:41,955 Reveals evidence of a 2,000-year-old battle 62 00:03:42,030 --> 00:03:45,122 Between the iron age britons and the roman army. 63 00:03:46,990 --> 00:03:51,682 Hidden beneath the soil, a vast array of ballistic weaponry. 64 00:03:52,990 --> 00:03:55,355 Lethal lead sling bullets. 65 00:03:55,364 --> 00:04:00,475 [andrew] these things will break limbs, they will shatter ribs. 66 00:04:00,510 --> 00:04:02,075 But the actual shockwave 67 00:04:02,110 --> 00:04:04,402 That's passed by one of these hitting you 68 00:04:04,477 --> 00:04:06,315 Could well simply stop your heart. 69 00:04:06,350 --> 00:04:08,955 [narrator] deadly sandstone missiles. 70 00:04:08,990 --> 00:04:12,395 These are the quintessential anti-personnel weapon. 71 00:04:12,404 --> 00:04:15,675 They're for damaging limbs, heads. 72 00:04:15,710 --> 00:04:18,635 Very, very dangerous weapon. 73 00:04:18,670 --> 00:04:21,915 [narrator] and terror-inducing projectiles. 74 00:04:21,950 --> 00:04:23,842 [john] the big ones will kill you 75 00:04:23,917 --> 00:04:26,475 Without you even knowing that they're even coming. 76 00:04:26,510 --> 00:04:29,915 But the little ones will force you to keep your head down. 77 00:04:29,950 --> 00:04:31,435 [narrator] the new discovery shows 78 00:04:31,510 --> 00:04:34,355 A very different type of roman warfare, 79 00:04:34,430 --> 00:04:36,835 Forgotten by history. 80 00:04:36,910 --> 00:04:40,635 Rather than swords and spears, these ballistic artifacts 81 00:04:40,670 --> 00:04:43,522 Were key to rome's success on the battlefield. 82 00:04:45,510 --> 00:04:48,195 The ancient equivalent of modern bullet casings 83 00:04:48,270 --> 00:04:49,522 And high-powered ammo. 84 00:04:51,230 --> 00:04:56,475 But what's puzzling is why they've been discovered here, 85 00:04:56,510 --> 00:04:59,915 Because burnswark was outside the roman empire, 86 00:04:59,950 --> 00:05:02,682 10 miles north of hadrian's wall. 87 00:05:03,870 --> 00:05:06,075 And, at the time of the attack, 88 00:05:06,150 --> 00:05:09,882 The wall had been in place for over 10 years. 89 00:05:11,710 --> 00:05:15,435 Romanist john reid believes the archeological evidence 90 00:05:15,510 --> 00:05:18,715 From an ancient structure on the summit of burnswark hill 91 00:05:18,750 --> 00:05:21,475 Could provide a clue. 92 00:05:21,550 --> 00:05:24,635 Hillforts were frequently built on the highest point around 93 00:05:24,670 --> 00:05:27,115 Giving the widest view of the area. 94 00:05:27,150 --> 00:05:29,115 They're usually heavily defended, 95 00:05:29,190 --> 00:05:32,075 They've got ditches and ramparts all the way around. 96 00:05:32,110 --> 00:05:35,115 This one had triple ditches on the south side. 97 00:05:35,190 --> 00:05:37,842 That is the side that is easiest to assault. 98 00:05:37,917 --> 00:05:39,955 So they were quite clearly making sure 99 00:05:40,030 --> 00:05:42,042 The defenses were strongest there. 100 00:05:43,390 --> 00:05:45,042 [narrator] rising up to 300 meters 101 00:05:45,117 --> 00:05:47,515 Above the surrounding terrain, 102 00:05:47,550 --> 00:05:50,795 Burnswark hill offered the greatest natural defense 103 00:05:50,830 --> 00:05:52,522 North of hadrian's wall. 104 00:05:53,950 --> 00:05:55,755 But the archeological evidence reveals 105 00:05:55,790 --> 00:05:57,882 It was more than just a fort. 106 00:06:00,110 --> 00:06:01,995 [john] people were living here, 107 00:06:02,030 --> 00:06:03,755 There would have been places for the children to play. 108 00:06:03,830 --> 00:06:05,515 So you're looking at a population up 109 00:06:05,550 --> 00:06:06,468 Here of two thousand 110 00:06:06,470 --> 00:06:08,075 Maybe two and a half thousand people. 111 00:06:08,150 --> 00:06:10,395 And at a time of great crisis 112 00:06:10,430 --> 00:06:13,282 That number would swell to maybe three times that. 113 00:06:14,477 --> 00:06:15,995 [narrator] for the local tribes, 114 00:06:16,004 --> 00:06:19,675 Burnswark would have seemed impregnable. 115 00:06:19,710 --> 00:06:21,682 But the roman army managed to bombard it 116 00:06:21,757 --> 00:06:25,115 With thousands of deadly projectiles. 117 00:06:25,190 --> 00:06:27,635 Now, nearly two thousand years on, 118 00:06:27,710 --> 00:06:30,315 Archeology is revealing the firepower 119 00:06:30,390 --> 00:06:34,075 Rome had at its disposal, 120 00:06:34,110 --> 00:06:37,762 And the tactics used to assault the native stronghold. 121 00:06:40,957 --> 00:06:44,235 These marks on the landscape below the hillfort 122 00:06:44,270 --> 00:06:47,562 Are the hallmarks of a vast roman military camp. 123 00:06:49,390 --> 00:06:52,395 Its size reveals that up to 4,000 soldiers 124 00:06:52,404 --> 00:06:56,155 Took up position beneath the southern slopes. 125 00:06:56,190 --> 00:06:58,402 While another 2,000 men were positioned 126 00:06:58,477 --> 00:07:01,275 Directly behind the fort in a second camp, 127 00:07:01,310 --> 00:07:04,795 Surrounding the ancient settlement. 128 00:07:04,870 --> 00:07:08,682 There is some sense of foreboding about this hilltop. 129 00:07:09,917 --> 00:07:11,475 So what was going on? 130 00:07:11,550 --> 00:07:14,882 Why is this hillfort held in the vice-like grip 131 00:07:14,957 --> 00:07:17,522 Of these two massive roman camps? 132 00:07:18,830 --> 00:07:20,315 [narrator] now the remains 133 00:07:20,350 --> 00:07:22,635 Of one heavily corroded projectile 134 00:07:22,710 --> 00:07:27,522 Unearthed at burnswark may provide an answer. 135 00:07:27,597 --> 00:07:31,042 This piece came from the excavation trench 136 00:07:31,117 --> 00:07:32,955 Up against the rampart. 137 00:07:32,990 --> 00:07:36,242 It was in at an angle wedged between two stones. 138 00:07:38,270 --> 00:07:40,002 [narrator] originally thought to be the remains 139 00:07:40,077 --> 00:07:42,515 Of an iron arrowhead, 140 00:07:42,590 --> 00:07:46,442 An x-ray scan reveals it was something far more deadly. 141 00:07:47,524 --> 00:07:49,315 [andrew] we can see the point, 142 00:07:49,390 --> 00:07:52,075 And we can see the socket at the other end 143 00:07:52,110 --> 00:07:54,955 Where the shaft would have been affixed to it. 144 00:07:54,990 --> 00:08:00,075 And inside you can actually see the square section 145 00:08:00,110 --> 00:08:03,835 Of the tapering point that will be designed 146 00:08:03,870 --> 00:08:08,515 To be able to penetrate armor as well as flesh. 147 00:08:08,590 --> 00:08:11,202 [narrator] this precision bolt could only have been fired 148 00:08:11,277 --> 00:08:14,482 From a very special piece of tactical artillery. 149 00:08:15,950 --> 00:08:17,915 It reveals the roman army was using 150 00:08:17,950 --> 00:08:20,682 The ancient equivalent of an assault rifle. 151 00:08:22,750 --> 00:08:24,955 And experts suspect the secret weapon 152 00:08:25,030 --> 00:08:28,715 That launched it was the manuballista. 153 00:08:28,750 --> 00:08:31,275 But until now, very few fragments 154 00:08:31,310 --> 00:08:34,522 Of rome's ultimate killing machine have ever been found. 155 00:08:36,637 --> 00:08:39,435 The presence of the lethal bolt tip suggests 156 00:08:39,510 --> 00:08:41,522 The manuballista played a key role 157 00:08:41,597 --> 00:08:43,362 In the attack on burnswark. 158 00:08:44,910 --> 00:08:48,242 And, if historical accounts of other roman campaigns 159 00:08:48,317 --> 00:08:51,522 Are to be believed, the local britons 160 00:08:51,597 --> 00:08:54,242 Wouldn't have stood a chance. 161 00:08:54,317 --> 00:08:56,722 [darius] procopius records in the gothic wars, 162 00:08:56,797 --> 00:09:00,315 At one point, the goths, outside the solaria gates, 163 00:09:00,350 --> 00:09:01,755 Are attacking the city, 164 00:09:01,790 --> 00:09:04,675 And one of these ballista is so powerful 165 00:09:04,750 --> 00:09:08,515 That a bolt shot from the gates of rome at the enemy, 166 00:09:08,590 --> 00:09:10,515 Literally pierces through the armor 167 00:09:10,590 --> 00:09:14,515 Of a goth and transfix him right to a pine tree. 168 00:09:14,590 --> 00:09:17,635 So this graphic detail is giving us an idea 169 00:09:17,710 --> 00:09:22,515 Of how powerful these weapons of war actually were. 170 00:09:22,590 --> 00:09:25,515 [narrator] evidence of rome's most feared weapon, 171 00:09:25,550 --> 00:09:27,515 Along with thousands of soldiers 172 00:09:27,550 --> 00:09:30,395 And hundreds of other deadly ballistics, 173 00:09:30,430 --> 00:09:32,002 Suggests the attack on burnswark 174 00:09:32,077 --> 00:09:36,875 Was both carefully planned and executed. 175 00:09:36,910 --> 00:09:40,555 The only outcome: A merciless annihilation 176 00:09:40,590 --> 00:09:43,802 Of thousands of men, women and children. 177 00:09:45,390 --> 00:09:48,555 So what does this strange site in scotland reveal 178 00:09:48,590 --> 00:09:52,715 About ancient rome's determination to rule the world? 179 00:09:52,750 --> 00:09:56,402 And how did their secret weapon help? 180 00:09:56,477 --> 00:09:59,842 [john] this was a massacre, this was mass slaughter. 181 00:10:02,110 --> 00:10:04,515 [narrator] new archeological discoveries have revealed 182 00:10:04,590 --> 00:10:08,675 That the roman army had developed a secret weapon. 183 00:10:08,750 --> 00:10:12,075 The manuballista, ancient rome's equivalent 184 00:10:12,110 --> 00:10:14,515 Of an assault rifle. 185 00:10:14,590 --> 00:10:18,722 Now a 1,900-year-old battlefield in southern scotland 186 00:10:18,797 --> 00:10:22,795 Is revealing the roman army's military tactics. 187 00:10:22,830 --> 00:10:25,595 And the role their secret weapon played 188 00:10:25,630 --> 00:10:29,675 In their merciless quest for global domination. 189 00:10:29,710 --> 00:10:32,155 You would have had absolute mayhem here 190 00:10:32,190 --> 00:10:34,235 With men, women and children, 191 00:10:34,244 --> 00:10:37,195 Animals all packed into a very tight space. 192 00:10:37,230 --> 00:10:38,995 It would have been absolute butchery 193 00:10:39,070 --> 00:10:40,882 And nobody would have stood a chance. 194 00:10:42,710 --> 00:10:44,515 [narrator] historical records from the time 195 00:10:44,590 --> 00:10:47,355 Suggest the manuballista was the most accurate 196 00:10:47,390 --> 00:10:50,362 And deadly weapon in the roman army's arsenal. 197 00:10:52,830 --> 00:10:55,595 But the archeological evidence of how it worked, 198 00:10:55,630 --> 00:10:58,682 And why it was so feared, is scarce. 199 00:11:01,790 --> 00:11:05,202 Fortunately, 1,500 miles from scotland, 200 00:11:05,277 --> 00:11:08,315 In the very heart of the roman empire, 201 00:11:08,350 --> 00:11:11,202 There's a clue as to how the manuballista 202 00:11:11,277 --> 00:11:12,642 May have been used. 203 00:11:14,590 --> 00:11:16,002 [darius] this is trajan's column. 204 00:11:16,077 --> 00:11:17,915 This is one of the most magnificent 205 00:11:17,950 --> 00:11:20,475 And well-preserved monuments from ancient roman times. 206 00:11:20,510 --> 00:11:22,635 It dates to the second century ad 207 00:11:22,670 --> 00:11:24,402 And narrates the battles fought 208 00:11:24,477 --> 00:11:29,035 And won by trajan from 102 to 106 against the datians. 209 00:11:29,070 --> 00:11:30,995 That's modern-day romania. 210 00:11:31,070 --> 00:11:33,642 [tense music] 211 00:11:37,150 --> 00:11:39,675 It literally is a textbook example 212 00:11:39,710 --> 00:11:43,675 Of how romans fought their war, waged their war, 213 00:11:43,710 --> 00:11:45,115 Built their military encampments, 214 00:11:45,150 --> 00:11:47,682 Foraged for food, destroyed the enemy. 215 00:11:49,630 --> 00:11:51,155 [narrator] as well as gruesome depictions 216 00:11:51,230 --> 00:11:53,195 Of death and butchery, 217 00:11:53,230 --> 00:11:56,675 The 38-meter-high column also reveals the weaponry 218 00:11:56,750 --> 00:11:59,882 Used by the roman army in major campaigns. 219 00:12:01,710 --> 00:12:06,402 In five separate scenes, roman soldiers can clearly be seen 220 00:12:06,477 --> 00:12:09,002 Manning a highly distinctive catapult. 221 00:12:10,670 --> 00:12:13,635 How it's depicted on the frieze indicates 222 00:12:13,710 --> 00:12:16,315 That it's rather small, even mobile it seems. 223 00:12:16,350 --> 00:12:20,235 In one instance it's actually located inside a wagon. 224 00:12:20,270 --> 00:12:22,235 It has this aura about it, 225 00:12:22,244 --> 00:12:25,635 Some kind of sophisticated mechanism that's involved 226 00:12:25,710 --> 00:12:28,642 In hurling projectiles at the enemy. 227 00:12:29,710 --> 00:12:31,635 [narrator] experts now agree 228 00:12:31,710 --> 00:12:33,635 The portable weapon in the carvings 229 00:12:33,710 --> 00:12:35,962 Is the elusive manuballista. 230 00:12:37,670 --> 00:12:40,155 It's hard evidence that the roman army 231 00:12:40,190 --> 00:12:41,675 Was using the killing machine 232 00:12:41,710 --> 00:12:44,762 20 years before their attack on burnswark. 233 00:12:46,317 --> 00:12:48,635 But even earlier images of the manuballista 234 00:12:48,710 --> 00:12:50,162 Have now been found. 235 00:12:52,750 --> 00:12:55,922 These drawings could help reveal how it works. 236 00:12:57,630 --> 00:13:00,955 But they weren't produced by the romans. 237 00:13:00,990 --> 00:13:04,195 They were found in a manuscript dated to the first century 238 00:13:04,270 --> 00:13:08,955 Written by the ancient greek inventor, hero. 239 00:13:08,990 --> 00:13:11,835 [darius] it's like getting the instructions to a model. 240 00:13:11,870 --> 00:13:13,275 This is a great resource. 241 00:13:13,310 --> 00:13:16,315 I mean, you have a written description 242 00:13:16,350 --> 00:13:18,075 And you have some of the imagery. 243 00:13:18,150 --> 00:13:20,875 We are seeing the same basic components. 244 00:13:20,910 --> 00:13:23,115 We have that arch in the front. 245 00:13:23,150 --> 00:13:26,115 We had these two kind of silos or towers. 246 00:13:26,190 --> 00:13:30,562 And those components match what we see on trajan's column. 247 00:13:32,270 --> 00:13:33,355 [narrator] the ancient drawings 248 00:13:33,390 --> 00:13:36,155 Clearly show the manuballista. 249 00:13:36,190 --> 00:13:38,722 And reveal vital components not visible 250 00:13:38,797 --> 00:13:41,635 In the stone carvings. 251 00:13:41,710 --> 00:13:44,562 But they don't show how they fit together. 252 00:13:46,404 --> 00:13:48,875 You turn the page and there's no conclusion. 253 00:13:48,910 --> 00:13:52,242 So ultimately you could say it falls short, 254 00:13:52,317 --> 00:13:53,675 But it's still giving us 255 00:13:53,710 --> 00:13:56,282 A lot of information about this device. 256 00:13:58,550 --> 00:14:00,002 [narrator] originally, the manuballista 257 00:14:00,077 --> 00:14:02,715 Was a greek invention. 258 00:14:02,750 --> 00:14:06,562 Decades later the designs found their way into roman hands, 259 00:14:06,637 --> 00:14:09,835 And were put to lethal effect. 260 00:14:09,870 --> 00:14:13,595 Can discovering exactly how the manuballista worked, 261 00:14:13,630 --> 00:14:15,675 And putting it to the test, 262 00:14:15,684 --> 00:14:20,635 Explain why it was so prized as a weapon by the roman army, 263 00:14:20,670 --> 00:14:22,842 And feared by their enemies? 264 00:14:26,430 --> 00:14:29,682 Now roman artillery expert, alan wilkins, 265 00:14:29,757 --> 00:14:34,482 And engineer, len morgan, have teamed up to do just that. 266 00:14:36,190 --> 00:14:39,035 Using all the available historical sources, 267 00:14:39,070 --> 00:14:42,075 Including pieces like the burnswark bolt, 268 00:14:42,110 --> 00:14:45,275 They've painstakingly pieced together all the evidence 269 00:14:45,310 --> 00:14:48,555 To reproduce a 21st century version 270 00:14:48,590 --> 00:14:50,795 Of the roman killing machine. 271 00:14:50,830 --> 00:14:53,035 It's a bit of a jigsaw to get it all together. 272 00:14:53,044 --> 00:14:55,515 But there's only one way to find out 273 00:14:55,524 --> 00:14:57,115 How any of these machines work, 274 00:14:57,150 --> 00:15:01,675 And that is to build them and then to test them. 275 00:15:01,710 --> 00:15:04,515 [narrator] the individual, precision-engineered parts 276 00:15:04,590 --> 00:15:08,235 Allow the weapon to be easily transported. 277 00:15:08,244 --> 00:15:11,922 But when slotted together they create a strong metal frame. 278 00:15:14,150 --> 00:15:18,522 The curved arch acts as a sight, giving pinpoint accuracy. 279 00:15:20,430 --> 00:15:22,315 While the weapon's firepower comes 280 00:15:22,350 --> 00:15:27,035 From two spring-loaded arms which ratchet back, 281 00:15:27,070 --> 00:15:28,722 Creating enough stored tension 282 00:15:28,797 --> 00:15:32,802 To fire a heavy iron bolt with lightning speed. 283 00:15:36,190 --> 00:15:38,882 What we've achieved with this, what we've produced, 284 00:15:38,957 --> 00:15:42,882 Would be instantly recognizable to a roman artilleryman. 285 00:15:42,957 --> 00:15:45,155 He might say, "well, nice try lads 286 00:15:45,230 --> 00:15:46,722 But you've got this little bit wrong," 287 00:15:46,797 --> 00:15:48,635 Or something like that, but generally speaking 288 00:15:48,670 --> 00:15:50,635 Working to the dimensions that we have, 289 00:15:50,670 --> 00:15:53,355 The information that we have, the archeological finds, 290 00:15:53,390 --> 00:15:56,155 We've produced a machine that a roman artilleryman 291 00:15:56,230 --> 00:15:59,675 Would recognize and be able to use. 292 00:15:59,684 --> 00:16:02,875 [narrator] this is the closest in 1,600 years 293 00:16:02,910 --> 00:16:06,722 Anyone has come to creating an authentic manuballista. 294 00:16:08,637 --> 00:16:12,795 Voila! The manuballista es parata... 295 00:16:12,870 --> 00:16:15,675 The manuballista is ready. 296 00:16:15,710 --> 00:16:17,595 [narrator] but will testing it reveal 297 00:16:17,630 --> 00:16:22,195 Why it took on such a mythical status?

purpose, 683 00:37:27,230 --> 00:37:31,755 And we think that purpose was to create terror. 684 00:37:31,830 --> 00:37:34,075 -[soldiers shouting] -[bullets whistling] 685 00:37:34,150 --> 00:37:36,635

their brutal assault on the hillfort's defenses. 702 00:38:24,884 --> 00:38:27,315 The heavily armed troops disgorged 703 00:38:27,390 --> 00:38:30,155 Out of these three big gateways down here 704

707 00:38:36,870 --> 00:38:38,395 They would have fought their way onto level ground, 708 00:38:38,430 --> 00:38:40,155 And once there, 709 00:38:40,190 --> 00:38:43,435 The roman troops would have been absolutely unbeatable. 710 00:38:43,470 --> 00:38:45,595 [narrator] as the survivors tried to escape, 711 00:38:45,670 --> 00:38:48,002 They were picked off by the second battalion 712

00:38:56,635 On the north side of the fort, 715 00:38:56,670 --> 00:39:00,002 Because we found a cluster of bullets at the north gate. 716 00:39:00,077 --> 00:39:03,315 And we think that that was an escape party 717 00:39:03,390 --> 00:39:05,675 Getting caught by fire. 718 00:39:05,710 --> 00:39:07,755 [narrator] the hillfort, and all in it, 719 00:39:07,830 --> 00:39:12,395 Was obliterated by

00:39:57,435 The whole might of rome facing tribesmen 733 00:39:57,470 --> 00:40:01,955 Who simply weren't equipped to be able to counter them. 734 00:40:02,030 --> 00:40:04,235 [narrator] 90 miles further north of burnswark 735 00:40:04,244 --> 00:40:06,882 Is the spot where lollius urbicus ended 736 00:40:06,957 --> 00:40:10,682 His bloody three-year campaign to capture the north. 737 00:40:12,190 --> 00:40:15,515 It was here the roman army built a new frontier 738 00:40:15,524 --> 00:40:20,235 For their new emperor: The antonine wall. 739 00:40:20,270 --> 00:40:23,315 For the romans, the campaign in scotland was a success. 740 00:40:23,390 --> 00:40:27,315 Antoninus was able to add the title of imperator, 741 00:40:27,390 --> 00:40:29,515 Meaning conqueror, to his name, 742 00:40:29,550 --> 00:40:31,995 As many of his predecessors had done, 743 00:40:32,030 --> 00:40:33,522 And therefore he was able 744 00:40:33,597 --> 00:40:36,362 To openly display his military might. 745 00:40:37,950 --> 00:40:39,675 [narrator] lollius urbicus had achieved 746 00:40:39,710 --> 00:40:42,635 All that the emperor had asked of him. 747 00:40:42,710 --> 00:40:45,795 And by the time the antonine wall was complete, 748 00:40:45,870 --> 00:40:47,882 The feared general was gone. 749 00:40:49,550 --> 00:40:52,355 It's almost as though he was kind of parachuted in 750 00:40:52,430 --> 00:40:55,355 To tackle the revolt of the tribes, 751 00:40:55,390 --> 00:40:58,802 And then once the job was finished, he returned to rome. 752 00:41:03,470 --> 00:41:05,635 [darius] afterwards, he comes to rome 753 00:41:05,710 --> 00:41:08,155 And he serves as the prefect of the city. 754 00:41:08,190 --> 00:41:10,635 And this is an important, important position, 755 00:41:10,670 --> 00:41:14,235 You're basically the number one of the city. 756 00:41:14,270 --> 00:41:17,675 [narrator] lollius urbicus would never return to britain. 757 00:41:17,710 --> 00:41:20,555 His merciless use of rome's most feared weapon 758 00:41:20,590 --> 00:41:22,882 To annihilate the opposition at burnswark 759 00:41:22,957 --> 00:41:27,195 Had paved the way for a victorious campaign. 760 00:41:27,204 --> 00:41:31,515 But, ultimately, it was all for nothing. 761 00:41:31,550 --> 00:41:34,875 Just eight years later, the romans retreated 762 00:41:34,884 --> 00:41:38,515 From the antonine wall back down to hadrian's wall. 763 00:41:38,590 --> 00:41:42,355 It's possible that this region was too difficult to govern, 764 00:41:42,430 --> 00:41:44,715 That the local tribes' resistance 765 00:41:44,750 --> 00:41:48,242 Made the roman presence there very challenging. 766 00:41:48,317 --> 00:41:50,195 [andrew] in many, many ways, roman britain 767 00:41:50,270 --> 00:41:52,675 Became a sort of nightmarish version 768 00:41:52,750 --> 00:41:55,515 Of a sort of modern afghanistan for western armies, 769 00:41:55,550 --> 00:41:57,795 Where you have the big military force 770 00:41:57,870 --> 00:42:00,002 Sitting in a landscape in their forts 771 00:42:00,077 --> 00:42:01,795 Trying to control a population 772 00:42:01,870 --> 00:42:05,515 That are sometimes for you and sometimes definitely not. 773 00:42:05,524 --> 00:42:08,635 [narrator] with the roman army back behind hadrian's wall, 774 00:42:08,670 --> 00:42:11,755 Local tribes took back control of the territory 775 00:42:11,790 --> 00:42:15,042 Conquered by lollius urbicus. 776 00:42:15,117 --> 00:42:17,915 The land we now know today as scotland 777 00:42:17,990 --> 00:42:20,715 Would never again succumb to roman rule. 778 00:42:20,750 --> 00:42:22,875 [tense music] 779 00:42:22,910 --> 00:42:25,635 The britons are going to give the romans a good fight. 780 00:42:25,710 --> 00:42:29,115 And the romans with their technology can take it so far, 781 00:42:29,150 --> 00:42:31,595 But there are going to be limitations. 782 00:42:31,670 --> 00:42:33,635 [andrew] the history of the northern part of britain 783 00:42:33,710 --> 00:42:36,635 Is one of the roman army attempting 784 00:42:36,670 --> 00:42:40,155 To finish the job again and again and again, 785 00:42:40,190 --> 00:42:43,595 And various roman emperors tried very, very hard 786 00:42:43,630 --> 00:42:45,275 To impose their rule. 787 00:42:45,310 --> 00:42:47,962 But in the end, not a single one of them could do it. 788 00:42:49,550 --> 00:42:52,315 [narrator] after the massacre at burnswark hill, 789 00:42:52,350 --> 00:42:55,842 Its blood-soaked ground would forever remain deserted. 790 00:42:57,117 --> 00:42:58,202 [man shouting] 791 00:42:59,630 --> 00:43:02,075 Today, it's an area of tranquility 792 00:43:02,110 --> 00:43:05,355 And outstanding natural beauty. 793 00:43:05,390 --> 00:43:08,555 But its slopes have revealed the terrifying force 794 00:43:08,590 --> 00:43:12,602 The roman army unleashed on anyone who stood in their way. 795 00:43:13,950 --> 00:43:16,235 And the secret weapon that helped rome 796 00:43:16,270 --> 00:43:21,522 Become the greatest and most feared civilization on earth. 797 00:43:21,597 --> 00:43:25,035 I don't think we can conceive of the terror 798 00:43:25,070 --> 00:43:29,042 That the people here felt as this was unfolding. 799 00:43:29,117 --> 00:43:31,355 But in the gloomy foreboding weather, 800 00:43:31,390 --> 00:43:34,242 There's a sense of something bad has happened here. 801 00:43:37,390 --> 00:43:39,202 [andrew] what is unique about burnswark 802 00:43:39,277 --> 00:43:41,435 Is that you can still walk around those fields 803 00:43:41,510 --> 00:43:43,835 And feel the ferocity of the roman army. 804 00:43:43,870 --> 00:43:46,675 They've got a range of options they can bring to bear. 805 00:43:46,750 --> 00:43:49,595 And if you are stuck inside a hillfort, 806 00:43:49,630 --> 00:43:52,442 And you think you're safe behind your palisade, 807 00:43:53,710 --> 00:43:55,675 Unfortunately, you're wrong. 808 00:43:55,710 --> 00:44:00,442
