Over the next weeks, Afranius attempted unsuccessfully to deal with the Caesarian harassment. Several siegeworks were begun by both Caesarian and Republican troops. Caesar states that during this time, the adversaries were so close that they could talk to each other. The republican troops were convinced to surrender, with even Afranius' own son attempting to negotiate a surrender. Soon after this, several Caesarian troops were found to have wandered into the Republican camp. Afranius and Petreius ordered their execution. At the same time, several Republican troops had been seen wandering about in Caesar's camp. Caesar ordered these men treated with respect and sent back to Afranius.
