Rommel also used wireless to order another gun line quickly to be set up with artillery and several anti-aircraft guns much further back, which knocked out 24 tanks in a few minutes on the flat ground between Mercatel and Tilloy. Just after Junkers Ju 87 of I and VIII arrived and made on the retiring tanks by Rommel ordered Panzer-Regiment 25 to return and cut off the British tanks but south of Duisans it met French tanks covering the British right flank and only pushed through after a long and costly engagement. When the German tanks had broken through a British anti-tank gun line, between Duisans and Warlus, the British tanks had already returned; the British attack had turned into a disaster and only 28 of the 88 tanks committed returned to their start line. The 6th Panzer Division signalled that "a strong enemy force was making a breakthrough" which caused alarm . Kleist ordered the 6th Panzer Division and 8th Panzer Division eastwards to counter the Allied breakthrough. In the aftermath the Germans treated the Battle of Arras as a minor defeat for the Allies.
