What were the major battles of WW2?Please describe the battles.

In addition to the turning points that I mentioned in answer to
your other question, here are some major battles:

• The
  Battle of Britain. This was an air battle over a number of months. In this battle, the German
  Luftwaffe tried to destroy the RAF and/or defeat the British by bombing their cities.
  


• Guadalcanal. This was a major battle between Japan and the US to
  control this strategically important island.


• Saipan, Iwo Jima,
  and Okinawa. These were huge battles that happened as the US fought its way towards the Japanese
  mainland.


• D-Day. The invasion of the European continent in June of
  1944 was a major battle and opened a western front that threatened Germany. The success of the
  landings essentially doomed Germany.
