Caesar

Now, Caesar had with him not more than three hundred horsemen and five thousand legionaries; for the rest of his army had been left beyond the Alps, and was to be brought up by those whom he had sent for the purpose. He saw, however, that the beginning of his enterprise and its initial step did not require a large force at present, but must take advantage of the golden moment by showing amazing boldness and speed,

since he could strike terror into his enemies by an unexpected blow more easily than he could overwhelm them by an attack in full force. He therefore ordered his centurions and other officers, taking their swords only, and without the rest of their arms, to occupy Ariminum, a large city of Gaul, avoiding commotion and bloodshed as far as possible; and he entrusted this force to Hortensius.
