LVIII.--Labienus at first attempted to raise vineae, fill up the marsh with hurdles and clay, and secure a road. After he perceived that this was too difficult to accomplish, he issued in silence from his camp at the third watch, and reached Melodunum by the same route by which he came. This is a town of the Senones, situated on an island in the Seine, as we have just before observed of Lutetia. Having seized upon about fifty ships and quickly joined them together, and having placed soldiers in them, he intimidated by his unexpected arrival the inhabitants, of whom a great number had been called out to the war, and obtains possession of the town without a contest. Having repaired the bridge, which the enemy had broken down during the preceding days, he led over his army, and began to march along the banks of the river to Lutetia. The enemy, on learning the circumstance from those who had escaped from Melodunum, set fire to Lutetia, and order the bridges of that town to be broken down: they themselves set out from the marsh, and take their position on the banks of the Seine, over against Lutetia and opposite the camp of Labienus. LIX.--Caesar was now reported to have departed from Gergovia; intelligence was likewise brought to them concerning the revolt of the Aedui, and a successful rising in Gaul; and that Caesar, having been prevented from prosecuting his journey and crossing the Loire, and having been compelled by the want of corn, had marched hastily to the province. But the Bellovaci, who had been previously disaffected of themselves, on learning the revolt of the Aedui, began to assemble forces and openly to prepare for war; Then Labienus, as the change in affairs was so great, thought that he must adopt a very different system from what he had previously intended, and he did not now think of making any new acquisitions, or of provoking the enemy to an action; but that he might bring back his army safe to Agendicum. For, on one side, the Bellovaci, a state which held the highest reputation for prowess in Gaul, were pressing on him; and Camulogenus, with a disciplined and well-equipped army, held the other side; moreover, a very great river separated and cut off the legions from the garrison and baggage. He saw that, in consequence of such great difficulties being thrown in his way, he must seek aid from his own energy of disposition.
