Operation Jubilee and Operation Rutter in Dieppe World war two?

Question

why allies was unsuccessful about Operation Jubilee and Operation Rutter?

Answer 1

Operation RUTTER is renamed Operation JUBILEE.

Although the code-name of the operation was changed, the plan remained the same. Operation Jubilee was now set for August 19 under the command of a Canadian officer, General J.H. Roberts.

The operation called for the landing of units of the Second Canadian Division supported by British Commandos on three beaches along the French coast. Puys and Pourville, two minor beaches on the flank, were to be captured at 4:50 a.m. Half an hour later, two Canadian infantry battalions, the Essex Scottish Regiment and the Royal Hamilton Light Infantry, were to raid the main objective, Dieppe. An armoured unit, the Calgary Regiment, was to support the infantry on the main beach. In addition, British commandos were to land on the flanks and neutralize German artillery.

Although this would be a frontal assault on a fortified port, it was hoped that the surprise element would allow the Canadians time to overrun the German defenses.

Answer 2

It was unsuccessful because it was not a proper invasion but just a raid to test the German defences and find out whether it would be possible to capture a port in a surprise attack.
The biggest equipment failure was that of the armoured vehicles which were unable to move off the shingle beach.
Many Canadian soldiers died or were captured but important lessons were learnt for D-Day in 1944.
The Allies realised they would have to take their port facilities with them so the design and construction of the Mulberry floating Harbours was begun and they realised that a good firm sand beach was the best surface for landing heavy equipment and getting soldiers quickly into combat so they eventually chose the Normandy beaches for the invasion

Answer 3
