The last major engagement of Becker's unit was Operation Bluecoat, another British offensive drive where Becker's weakened unit was committed to slow the progression of the 11th Armoured Division south of Saint-Martin-des-Besaces. On 1 August 1944 while in Le Tourneur Becker was injured in the left thigh by schrapnel from an artillery round.(ref Das Bundesarchiv, Aug. 2019) Those assault guns of Becker's battalion that survived this engagement were destroyed in the Falaise Gap. Becker and some of his men managed to escape the encirclement and retreated across northern France and into Belgium.
