Jerry & Jim;
The words on my post were not mine. This was taken off of the internet. Here is more that I found.
Operation Jubilee
Almost all concerned believed that a raid on Dieppe was now out of the question; however, though
Montgomery wanted it cancelled indefinitely, Mountbatten did not. He began reorganising the raid from
11 July as
Operation Jubilee. Despite not receiving Combined Chiefs of Staff authorisation, Mountbatten instructed his staff to proceed in late July. This lack of top-level go-ahead resulted in certain dislocations in the planning. For example, the failure to inform the
Joint Intelligence Committee or the
Inter-Service Security Board meant none of the intelligence agencies were involved, consequently the operation was mounted on information that was months out of date.
