During the first part of 1942 the British and Americans had many code names for possible plans of attack in Europe. These names were often used by different people for slightly different plans which made for constant redefinition each time the code word was used.         Acrobat – An advance in North Africa                                                                                             Bolero – Main invasion into France. This became ‘Overlord’.                                                         Gymnast – Landing in Vichy Northwest Africa, this became ‘Torch’.                                             Jupiter – Operations in Norway. This was important because the main way to supply Russia with much needed supplies was via the Arctic route. With Germany in control of northern Norway many supply convoys suffered VERY heavy losses.                                                           Round-Up – The invasion of Europe. This also eventually became part of ‘Overlord’.                 Sledgehammer – The attack on Brest or Cherbourg in 1942.                                                          And MANY more

Russia pressed VERY hard for some operation in western Europe in 1942 but the Allies did not feel that they could successfully accomplish this until 1943. And this eventually was pushed to 1944.
