The Roman History · Amm. 17.8.1

Cæsar, passing his winter among the Parisii, was eagerly preparing to anticipate the Allemanni, who were not yet assembled in one body, but who, since the battle of Strasburg, were working themselves up to a pitch of insane audacity and ferocity. And he was waiting with great impatience for the month of July, when the Gallic campaigns usually begin. For indeed he could not march before the summer had banished the frost and cold, and allowed him to receive supplies from Aquitania.
