I don’t know what “Sledgehammer” was” but” Rutter” was cancelled because of the weather and the fact that once “Rutter” set sail they had been seen by the Germans and surprise was lost. Mountbatten was a Grandson of Queen Victoria who reasoned and stated so that the Germans knew about “Rutter” and that they would not expect that someone would be so stupid to attack in the same place at a later date. “Rutter” was renamed “Jubilee” and went ahead . Montgomery and Roberts(commander of the Canadian 2nd division) both objected but Mountbatten pushed ahead anyway without getting the required authorization from the joint chiefs of staff.
Mountbatten had an estate in Ireland and he chose to ignore security advice not to sail his boat . He did anyway , the IRA had planted a bomb on board and his death brought attention to the IRA cause.
His titles etc , as if some how his poo isn’t poo ,
Admiral of the Fleet The Right Honourable The Earl Mountbatten of Burma, KG, GCB, OM, GCSI, GCIE, GCVO, DSO, PC
According to David Eisenhower's glossary, SLEDGEHAMMER was a "Contingency plan for a cross-Channel invasion of Europe in the fall of 1942 in the event that the threatened collapse of Russia made it necessary to open a diversionary front in Western Europe."
I see that you're a Canadian and a WWII history buff. So, just out of curiosity, can you please summarize the role of Canadian units in WWII? I know that your First Army played significant part in the invasion of Normandy and then continued eastward and northward into the Netherlands and Germany until the time of the German surrender, on the northern flank of the Allied advance. I'd assume that Canadians might have been on the Italian front as well. Any other geographic locations?
