By 18 May, Junck's force had been whittled down to 8 Messerschmitt Bf 110s, 4 Heinkel He 111s, and 2 Junkers Ju 52s. This represented a roughly 30 percent loss of his original force. With few replacements available, no spares, poor fuel and aggressive attacks by the British, this rate of attrition did not bode well for Fliegerführer Irak.
