Though Caesar was fully sensible, that to finish the war at a blow, he must pass the sea immediately, and endeavour to come up with Pompey, before he could draw his transmarine forces together; yet he dreaded the delay and length of time that such a project might require; because Pompey having carried with him all the ships on the coast, rendered the present execution of the design impracticable. He must therefore wait the arrival of ships from Picenum, Sicily, and the remoter coasts of Gaul, which was a tedious business, and, at that season of the year, subject to great uncertainty. It appeared likewise of dangerous consequence, to suffer a veteran army, and the two Spains, one of which was wholly devoted to Pompey, to strengthen themselves in his rival's interest; to let them grow powerful by levies of horse and foot, and leave Gaul and Italy open to their attacks in his absence.
