[Sidenote: May, B.C. 48.] Though still far outnumbered, Caesar was now in a condition to meet Pompey in the field, and desired nothing so much as a decisive action. Pompey would not give him the opportunity, and kept within his lines. To show the world, therefore, how matters stood between them, Caesar drew a line of strongly fortified posts round Pompey's camp and shut him in. Force him to surrender he could not, for the sea was open, and Pompey's fleet had entire command of it. But the moral effect on Italy of the news that Pompey was besieged might, it was hoped, force him out from his entrenchments. If Pompey could not venture to engage Caesar on his own chosen ground, and surrounded by his Eastern friends, his cause at home would be abandoned as lost. Nor was the active injury which Caesar was able to inflict inconsiderable. He turned the streams on which Pompey's camp depended for water. The horses and cattle died. Fever set in with other inconveniences. The labor of the siege was, of course, severe. The lines were many miles in length, and the difficulty of sending assistance to a point threatened by a sally was extremely great. The corn in the fields was still green, and supplies grew scanty. Meat Caesar's army had, but of wheat little or none; they were used to hardship, however, and bore it with admirable humor. They made cakes out of roots, ground into paste and mixed with milk; and thus, in spite of privation and severe work, they remained in good health, and deserters daily came into them. So the siege of Durazzo wore on, diversified with occasional encounters, which Caesar details with the minuteness of a scientific general writing for his profession, and with those admiring mentions of each individual act of courage which so intensely endeared him to his troops. Once an accidental opportunity offered itself for a successful storm, but Caesar was not on the spot. The officer in command shrank from responsibility; and, notwithstanding the seriousness of the consequences, Caesar said that the officer was right. [Sidenote: June, B.C. 48.] Pompey's army was not yet complete. Metellus Scipio had not arrived with the Syrian legions. Scipio had come leisurely through Asia Minor, plundering cities and temples and flaying the people with requisitions. He had now reached Macedonia, and Domitius Calvinus had been sent with a separate command to watch him. Caesar's own force, already too small for the business on hand, was thus further reduced, and at this moment there fell out one of those accidents which overtake at times the ablest commanders, and gave occasion for Caesar's observation, that Pompey knew not how to conquer.
