Appian of Alexandria Civil Wars 2.6.43

[43] To Afranius and some of the other officers it now seemed best to abandon Spain to Caesar, provided they could go unharmed to Pompey. Petreius opposed this and ran through the camp killing those of Caesar’s men whom he found holding communication with his own. He even slew with his own hand one of his officers who tried to restrain him. Moved by these acts of severity on the part of Petreius, the minds of the soldiers were still more attracted to the clemency of Caesar. Soon afterward Caesar managed to cut off the enemy’s access to water, and Petreius was compelled by necessity to come with Afranius to a conference with Caesar between the two armies. Here it was agreed that they should abandon Spain to Caesar, and that he should conduct them unharmed to the other side of the river Varus ¹ and allow them to proceed thence to Pompey. Arrived at this stream, Caesar called a meeting of all those who were from Rome or Italy and addressed them as follows: My enemies (for by still using this term I shall make my meaning clearer to you), I did not destroy those of you who surrendered to me when you had been sent to seize my camp, nor the rest of your army when I had cut you off from water, although Petreius had previously slaughtered those of my men who were intercepted on the other side of the river Sicoris. If there is any gratitude among you for these favors tell them to all of Pompey’s soldiers. After speaking thus he dismissed them uninjured, and he appointed Quintus Cassius governor of Spain. So much for the operations of Caesar. ²
