According to Wikipedia, ''On 1 November 1919, two days after the French take-over of Maraş, S�t�� İmam Incident, termed after the defender of three Turkish women who were being harassed and molested in the street by French Armenian Legion auxiliaries, sowed the seeds of tension in the city. S�t�� İmam shot one of the molesters in the skirmish and had to go into hiding. The incident triggered a series of events that led the Turkish majority of Maraş to rise against the occupation forces and culminated in the wholescale urban warfare two months after the incident.''
Elsewhere it is related that, with the whole Turkish population against them, the French were seriously outnumbered, and were running short of ammunition.
