Suggesting split 

This article is really about two different campaigns, fought in some of the same locations, but a few years apart and by slightly different countries:
1 the "Blitzkreigs" of 1939-40
2 the "Second Front" of 1944-45. 

The "Interlude" section is somewhat relevant to both — as an afterword to the first part and a preamble to the second.

I suggest splitting it into:

Western front (1939-40)
Western front (1944-45)

Apart from anything else, it seem odd to me that we don't have overview articles about either of the above subjects. What do others think? Regards,  | Talk
