On reaching Basra, the troops of Ali camped outside the city. It was a large army, and the camp was spread over several miles. The pro-Alid people of Basra who had evacuated the city on its cooperation by the confederates also joined the camp. Some other tribes in the neighborhood of Basra also joined the camp. Ali instructed his men to remain at peace. According to his instructions war was not to be resorted to, until all possibilities of peace had been exhausted.
