During September–October 1956, as plans began to mature for the invasion of the Sinai Peninsula, Dayan ordered a series of large-scale cross-border raids. On the night of 25 September, following a number of incidents including the machine-gunning of large gathering at Ramat Rachel in which four Israelis were killed, and the murder of a girl southwest of Jerusalem, the 890th Battalion attacked the Husan police station and nearby Arab Legion positions close to the armistice lines. Thirty-seven Legionnaires and National Guardsmen were killed as well as two civilians. Nine or ten paratroopers were killed, several in a road accident after the attack.
