The Omaha Beach Mulberry was abandoned after it was damaged by a storm on 19–22 June, however this loss was mitigated as the amount of supplies landed directly over the beach was far in excess of expectations.[21] Although Cherbourg was captured on 27 June, the port had been destroyed and required rebuilding, resulting in it receiving only a trickle of supplies by the end of July.[22]
In early July, an alternative to capturing Brittany was proposed: moving eastward to surround and defeat German forces west of the Seine, with supplies coming from captured ports on the Seine. Although the planners could see the advantages of the scheme, they insisted that US logistics depended on the Brittany ports and the Seine ports could not replace them. Therefore, both General Eisenhower and General Montgomery continued to stress the necessity of capturing the Brittany ports, recognizing that without them Allied logistics would be inadequate.[23]
The capture of the Quiberon Bay area was deemed important enough that consideration was given to a combined airborne and amphibious operation, Operation Hands Up to capture the area but, as the operation was deemed risky, it was agreed that it would only be attempted in the event that the advance into Brittany was delayed into September.[24]
