He had given command of the cavalry to Labienus, the former commander of Caesar's favorite X legion. He deployed the rest of the army on his left together with his auxiliary troops. Pompey's plan was to allow Caesar's infantry to advance, have his cavalry attack and push back the numerically inferior Julian horses, and then attack Caesar's infantry from behind. Pompey had disclosed his battle plans to companions days before the battle, and Caesar became aware of them. This is the Surprise Principal, Pompey thought that he would be able to out maneuver Caesar’s army but Caesar found out about beforehand giving him the advantage. Caesar also deployed in three lines. He arrayed his men 6 men deep. He rested his left on the marshland of the river and he positioned all his cavalry on the right, against Pompey's squadrons. Behind them he hid light troops, carrying javelins and other weapons, in anticipation of Pompey's cavalry. Caesar himself commanded his cavalry. He also had 2,000 legionaries as reserves. He posted the notorious tenth legion on his right under Sulla, with the understrength eighth and possibly the ninth on his left under Antonius. In the center he designated Domitius as the commanding officer. According to his accounts, he had 80 cohorts on the battlefield, about 22,000
