JAPANESE DIVE BOMBER PLUNGING TOWARD THE SEA, downed by antiaircraft fire from a Navy carrier during the Battle of the Philippine Sea, which started on 19 June. Aircraft in the foreground are Grumman Avengers (TBF-1 torpedo bombers). A Japanese naval force approaching the Marianas caused U.S. ships at Saipan, except for those unloading the most necessary supplies, to withdraw to the east. Troops ashore were left without naval gunfire, air support, or sufficient supplies.
