Operation Hands Up was an Allied plan in World War II to seize the Quiberon Bay area in southern Brittany. Two purposes have been suggested for the operation. Firstly, as a part of Operation Chastity, to enable the area to be developed as a deep-water port for supplying allied armies, supplementing the routes through Normandy, following the anticipated break-out from Normandy. Secondly, as an entry point for further armies shipped directly from the United States to support the break-out and possibly out-flank the German 7th Army.
