Thither came the two legions of Luceria and such recruits as Pompeius had been able hastily to collect in the deserted Apulia, as well as the troops raised by the consuls and other commissioners in Campania and conducted in all haste to Brundisium; thither too resorted a number of political fugitives, including the most respected of the senators accompanied by their families.

The embarkation began; but the vessels at hand did not suffice to transport all at once the whole multitude, which still amounted to 25,000 persons.

No course remained but to divide the army.

The larger half went first (4 March); with the smaller division of some 10,000 men Pompeius awaited at Brundisium the return of the fleet; for, however desirable the possession of Brundisium might be for an eventual attempt to reoccupy Italy, they did not presume to hold the place permanently against Caesar.

Meanwhile Caesar arrived before Brundisium; the siege began.
