"Elated by their glory, our army exclaimed that nothing could resist their valour--that they must penetrate the recesses of Caledonia, and at length after an unbroken succession of battles, discover the furthest limits of Britain." Agricola's Early Campaign in WalesIn 78AD, Gnaeus Julius Agricola succeeded Sextus Julius Frontinus as governor of Britain. Frontinus had expanded the province into Wales, where he conquered all but the northern section. Agricola had previously served in Britain as tribune under Suetonius Plautinus and as commander of Legio XX under Vetius Bolanus and Petillius Cerialis, later becoming the governor of Aquitania in 74AD before arriving back in Britain as governor. Agricola's Welsh campaign against the Ordovices, to complete the work of Frontinus, was completely successful:
The next few years saw Agricola leading campaigns northward, primarily to the Scottish lowlands, and by 80AD, about as far as the River Tay (Tacitus, 22, Agricola: Tanaum or Taus). His forces skirmished with the tribes and secured lines of communication. Agricola's army built some "1,300 miles of roads in northern Britain, primarily to assist his military activity by linking over sixty forts and fortlets from Yorkshire-Lancashire to the edge of the Highlands." (Fry, Roman Britain, p. 79) He toyed with sending an expedition to Ireland, figuring it would take "a single legion and a few auxilia" (Tacitus, 24, Agricola) or about 8,000-10,000 men, to secure that island, but was ordered by the Emperor Domitian to secure the area in Britain north across the Firth-Clyde isthmus. In the summer of 83, despite sending thousands of legionnaires back to the mainland to support Domitian's expedition agains the German tribes, he advanced again, as well as sent ships up the North Sea to explore the coast and look for suitable landing sites. This evidently provoked the Caledonians, and Legio IX's camp came under attack. The Caledonians attacked during the night, but a relieving force of cavalry and infantry sent by Agricola at dawn chased them away:
However, the Caledonians were heartened by the action, and began to mass troops for a final battle under the leader Galgacus, also translated as Calgacus, the Romanized form for the Celtic word calgaich, meaning swordsman (Fry, The History of Scotland, p. 23). To Mons GraupiusAgricola advanced "as far as the Grampian Mountains" (Tacitus, 29, Agricola), somewhere "north and northeast of Perth." (Collingswood, Roman Britain, p.23) Although the actual battlefield remains in some doubt, one possibility is "on a hill in Bennachie, some 18 miles northwest of Aberdeen, and about four miles from Durno." (Fry, Roman Britain, p. 81, and Fry, The History of Scotland, p. 24 quoting article by J. K. St. Joseph in Brittania). Durno is the site of an Agricolan military camp. Another places Agricola "at Raedykes near Stonehaven" (Herm, The Celts, p. 222) Wherever the battlefield is located, the Caledonians held the hills. "The enemy, to make a formidable display, had posted himself on high ground." (Tacitus, 35, Agricola). Galgacus gave a speech to the assembled troops on the evils of the Romans and the virtues of freedom.
As the Caledonians formed up, Agricola, with the Romans assembled on the plains, then gave a speech extolling the virtues of Roman might and disparaging the Britons' military prowess, and he arrayed his forces to face the Caledonians. ForcesAccording to Tacitus, the Caledonians massed 30,000 troops in the foothills, including chariots and cavalry. The army consisted of:
And they were arrayed as such:
"And now was seen the assembling of troops and the gleam of arms, with the boldest warriors stepped to the front." (Tacitus, 33, Agricola) From the battle description, the chariots and cavalry were posted in the van on the plains along with skirmishers, with the rest of the troops upon the slopes. Agricola faced them with 8,000 auxilia infantry and 3,000 cavalry, with another 2,000 cavalry ("four alae") in reserve. Among the auxilia were "three Batavian and two Tungrian cohorts," which usually consists of 500 (quingenaria) men, or in some cases and generally from the Flavian era onward, 1000 (milliaria) men. The "other auxiliary cohorts" are not named, but in the pre-battle speech, Galgacus notes "in the very ranks of the enemy, we shall find our own forces," (Tacitus, 32, Agricola) meaning Britons, Gauls, and Germans. In addition, in reserve:
How many legionnaires is not known, since some were siphoned off for Domitian's campaign. At the time, there were four legions in Britain: II Augusta, XX Valeria Victrix, IX Hispania, and II Adiutrix. At the beginning of Agricola's Scottish campaign, II Augusta was centered at Caerleon, IX Hispania at York, and XX Valeria Victrix and II Adiutrix at Chester. (Evans, Soldiers of Rome, p.82, 159). Vexillations (detachments) were taken from all four legions and sent to Domitian. (Webster, Roman Imperial Army, p. 56). The size of these detachments were 1,000 to 2,000 per legion, (Le Bohec, The Imperial Roman Army, p.30), although it could be less, for example, "2,000 men belonging to three legions" (Suetonius, The Twelve Ceasars, p. 282) Tacitus writes about the Britons "disdaining the smallness of our numbers." (Tacitus, 37, Agricola). Tacitus notes that for this campaign:
Counting losses, garrisons, and detachments, and with the idea of a "lightly equipped force" and "smallness of our numbers," it is possible that the legions were much depleted at the battle, perhaps no more than 15,000 troops, probably even less. Note that in a pre-battle speech, Galgacus notes, "behind them you have nothing to dread, the forts are ungarrisoned" (Tacitus, 32, Agricola) although this entire speech should be considered a work of fiction and writer's editorial license more than hard fact. Agricola stretched his men to cover his front.
Yet he did not, and in a display of confidence, or in a bit of Tacitus' well known drama, he "sent away his horse and took his stand on foot before the colours." (Tacitus, 35, Agricola) The Battle of Mons GraupiusAt first, "the plain between resounded with the noise and rapid movements of cavalry and chariots" (Tacitus, 35, Agricola) akin to previous battles. The chariots,
Then the battle of the infantry started with an exchange of missile fire.
Agricola then sent in the Batavians and Tungrians into melee, and they began to
The other cohorts "joined in eager rivalry in cutting down all the nearest of the foe" and the Roman auxiliaries worked their way up the slope. In the meantime, the Caledonian cavalry was driven off, presumably by the Roman cavalry. At this point, the Caledonians on the hill "begun gradually to descend, and to hem in the rear of the victorious army" (Tacitus, 37, Agricola), evidently performing the enveloping maneuver Agricola had tried to avert with the stretching of his line. The 3,000 Roman cavalry, which successfully had sent the Caledonian cavalry packing, failed to stop this assault, and was pushed back.
However, Agricola commmitted the 2,000 cavalry in reserve, and they pitched into the flank of the enveloping Caledonians, routed them, and pursued.
The Caledonians fled, and the Roman auxiliaries pursued and slaughtered their foe.
Although there were occasional stands, the Roman victory was complete. Tacitus describes a successful rally and counterattack at a woods, which ambushed the over-eager pursuers. Agricola threw a cordon of light cohorts around the wood and sent a mixed force of infantry and dismounted cavalry troopers into the wood to flush out the Caledonians. Except for these temporary rallies, the Caledonians "sought the shelter of distant and pathless wilds." (Tacitus, 37, Agricola) Tacitus contends 10,000 Caledonians were killed versus the loss of 360 Romans, and presumably this does not include the inevitable losses of the Roman auxilia. Agricola sent out scouts to ascertain where the enemy fled, but they were too dispersed,and he marched his army back into winter quarters. Agricola had been governor of Britain for six years (twice the normal time), and was recalled by the Emperor Domitian and given triumphal honors, including a statue. Court intrigue followed, so says Tacitus, and Agricola was put out to pasture amidst innuendo. Agricola's successors never completed the conquest of Caledonia, and plagued by diverting detachments to mainland Europe, eventually retreated southwards and abandoned Agricola's conquests. SourcesThe primary source material comes from Tacitus' Life of Agricola. Tacitus was the son-in-law of Agricola, and extols virtue after virtue. He is also privy to more first-hand information about the Battle of Mons Graupius than other battles in his histories, where his battle descriptions tend to be repetitive, and indeed, suspect. Of further confusion are the various translations of his works, in which the translators provide a particular wording that does not necessarily mirror the other translations. Take, for example, the line about the pursuit of the defeated Caledonians, and these two translations:
"Our men pursued, wounded, made prisoners of the fugitives only to slaughter them when others fell in their way." Between the two translations, there is a subtle difference, although both agree that the prisoners were executed. The other source material come from Cassius Dio, who devotes only a short sentence to the campaigns of Agricola in his book on Roman History:
Archeological excavations in Scotland confirms the construction of the Roman forts, fortlets, and small towns, and helps narrow the search for the battle site. Note that the research regarding the battlefield location was presented in Brittania by J. K. St. Joseph and David Wilson, both of the Cambridge University Aerial Photography Unit.
