 Because of his health, Octavian remained in camp while his lieutenants assumed a position on the left flank opposite Brutus.In the resulting first battle of Philippi, Antony defeated Cassius and captured his camp while Brutus overran Octavian's troops and penetrated into the Triumvirs' camp but was unable to capture the sick Octavian.The battle was a tactical draw but due to poor communications Cassius believed the battle was a complete defeat and committed suicide to prevent being captured.
