6,000 Iraqi troops with 30 artillery pieces departed Baghdad, Iraq on an ostensibly training exercise before dawn. At first light, they reached a plateau overlooking the RAF airbase at Habbaniya 45 miles west of Baghdad. British Ambassador Kinahan Cornwallis warned British civilians to leave Baghdad; 230 of them would soon flee to Habbaniya while 350 and 150 would seek shelter in the British Embassy and the American Legation, respectively.
