22. The military expeditions of the third year [94] discovered new nations to the Romans, and their ravages extended as far as the estuary of the Tay. [95] The enemies were thereby struck with such terror that they did not venture to molest the army though harassed by violent tempests; so that they had sufficient opportunity for the erection of fortresses. [96] Persons of experience remarked, that no general had ever shown greater skill in the choice of advantageous situations than Agricola; for not one of his fortified posts was either taken by storm, or surrendered by capitulation. The garrisons made frequent sallies; for they were secured against a blockade by a year's provision in their stores. Thus the winter passed without alarm, and each garrison proved sufficient for its own defence; while the enemy, who were generally accustomed to repair the losses of the summer by the successes of the winter, now equally unfortunate in both seasons, were baffled and driven to despair. In these transactions, Agricola never attempted to arrogate to himself the glory of others; but always bore an impartial testimony to the meritorious actions of his officers, from the centurion to the commander of a legion. He was represented by some as rather harsh in reproof; as if the same disposition which made him affable to the deserving, had inclined him to austerity towards the worthless. But his anger left no relics behind; his silence and reserve were not to be dreaded; and he esteemed it more honorable to show marks of open displeasure, than to entertain secret hatred. 23. The fourth summer [97] was spent in securing the country which had been overrun; and if the valor of the army and the glory of the Roman name had permitted it, our conquests would have found a limit within Britain itself. For the tides of the opposite seas, flowing very far up the estuaries of Clota and Bodotria, [98] almost intersect the country; leaving only a narrow neck of land, which was then defended by a chain of forts. [99] Thus all the territory on this side was held in subjection, and the remaining enemies were removed, as it were, into another island.
