There was a universal shout of “No!” On hearing this he held his shield above his head and ran to the gate, the men followed his example, and roofing themselves with their shields burst through into the city.[*](This evolution was frequently practised. The shield (scutum) of the Roman legionary was a ponderous arrangement of stout planks, convex on the outside, about 4 ft. long and 21/2 broad. In forming the shield roof they held their shields horizontally over thier heads, of course on the left arm, and as the shields were broad enough to touch each other, the appearance was that of a roof of gigantic tiles. This was called by the Romans a testudo (tortoise shell) and was frequently used as a protection for storming parties.) They dislodged the Samnites from the walls on either side of the gate, but as they were only a small body did not venture to penetrate into the interior of the city.
The consul was at first unaware of what was going on, and was anxious to recall his troops, for the sun was now rapidly sinking and the approaching night was making every place suspicious and dangerous, even for victorious troops.
After he had ridden forward some distance he saw that the camp on his right hand had been captured, and he heard at the same time the mingled clamour of shouts and groans arising in the direction of the city on his left; just then the fighting at the gate was going on.
