An eyewitness account of events during the Armed Police mutiny part way down this page:Could be Aden 1967 in crater where a number of soldiers from 1 RNF and 1 A&SH were ambushed and killed by the Arab National Police. A number of soldiers from the RCT returning from a range day in a bedford RL were ambushed as they were passing the Police lines. There was stand off for a few days until Mad Mitch and the Argyles went into retake Crater with bayonets fixed and pipes playing.
I think there were over 30 dead. The dead bodies of the soldiers from patrols ambushed were abandoned when the British withdraw. After the bodies were retrieved after Mad Mitch's reoccupation there was allegations that some of the bodies had been mutilated by the locals.
