The Batavians and the Germans from across the Rhine[302] now formed up tribe by tribe--the separation was designed to show their individual prowess--and opened fire from a distance. Finding that most of their missiles fell harmlessly on to the turrets and pinnacles of the walls, and that they were being wounded by stones hurled from above, they charged with a wild shout and surged up to the rampart, some using scaling-ladders, others climbing over their comrades who had formed a 'tortoise'. But no sooner had some of them begun to scale the wall, than they were hurled down by the besieged, who thrust at them with sword and shield, and buried under a shower of stakes and javelins. The Germans are always impetuous at the beginning of an action and over-confident when they are winning; and on this occasion their greed for plunder even steeled them to face difficulties. They actually attempted to use siege-engines, with which they were quite unfamiliar. But though they had no skill themselves, some of the deserters and prisoners showed them how to build a sort of bridge or platform of timber, on to which they fitted wheels and rolled it forward. Thus some of them stood on this platform and fought as though from a mound, while others, concealed inside, tried to undermine the walls. However, stones hurled from catapults soon destroyed this rude engine. Then they began to get ready hurdles and mantlets, but the besieged shot blazing spears on to them from engines, and even attacked the assailants themselves with fire-darts. At last they gave up all hope of an assault and resolved to try a waiting policy, being well aware that the camp contained only a few days' provisions and a large number of non-combatants. They hoped that famine would breed treason, and counted, besides, on the wavering loyalty of the slaves and the usual hazards of war to aid them.
