Overnight, Iraqi troops withdrew from the plateau overlooking RAF Habbaniya after suffering 1,000 casualties, largely by RAF aircraft, abandoning large amounts of weapons and supplies. They were pursued by the British King's Own Royal Regiment, which caught up with the Iraqi troops at Sinn El Dhibban, taking 433 prisoners at the cost of 7 British troops killed and 14 wounded. To the south, the 21st Infantry Brigade of the Indian 10th Division arrived by sea at Basra. Meanwhile, Vichy France and Germany signed the Paris Protocol, which gave permission for German troops to march through Syria for Iraq to reinforce the Iraqis; in return, Germany lowered the tribute that France had to pay Germany from 20 million to 15 million Reichsmarks daily. German Luftwaffe Colonel Werner Junck was ordered to establish Fliegerführer Irak with 12 Bf 110 fighters and 12 He 111 bombers.
