Sortie 106G/1138 was flown in the aftermath of a series of heavy storms which damaged the artificial harbour at Vierville, Normandy. This harbour, codenamed 'Mulberry A', was constructed of prefabricated sections which had been towed across the English Channel after D-Day and assembled to form breakwaters, unloading piers and floating pontoon roadways. These extensive temporary structures were vital to the Allied logistic effort in the absence of a deep-water port and played a major part in supporting the ongoing battle for Normandy.
