Lieutenant Commander Edward Henry O’Hare
(March 13, 1914 – November 26, 1943

On June 7, 1942, the Battle of Midway—one of the most decisive
U.S. victories in its war against Japan—came to an end. In the
four-day sea and air battle, the outnumbered U.S. Pacific Fleet
succeeded in destroying four Japanese aircraft carriers with the
loss of only one of its own, the Yorktown, thus reversing the tide
against the previously invincible Japanese navy.

On June 4, 1942, the Battle of Midway—one of the most decisive
U.S. victories against Japan during World War II—began. During
the four-day sea-and-air battle, the outnumbered U.S. Pacific
Fleet succeeded in destroying four Japanese aircraft carriers
while losing only one of its own, the Yorktown, to the previously invincible Japanese navy.

On May 3, 1942, during World War II, the first modern naval
engagement in history, the Battle of the Coral Sea, began. A
Japanese invasion force succeeds in occupying Tulagi of
the Solomon Islands in an expansion of Japan’s defensive
perimeter.

The United States, having broken Japan’s secret war code
and forewarned of an impending invasion of Tulagi and Port
Moresby, attempted to intercept the Japanese armada. Four
days of battles between Japanese and American aircraft
carriers resulted in 70 Japanese and 66 American warplanes
destroyed.

Aboard the USS Missouri in Tokyo Bay, Japan formally surrendered to the
Allies (above) bringing an end to World War II.

By the summer of 1945, the defeat of Japan was a foregone conclusion. The Japanese navy and air force were destroyed. The Allied naval blockade of
Japan and intensive bombing of Japanese cities had left the country and
its economy devastated. At the end of June, the Americans captured
Okinawa, a Japanese island from which the Allies could launch an invasion
of the main Japanese home islands. U.S. General Douglas MacArthur was
put in charge of the invasion, which was code-named “Operation Olympic”
and set for November 1945.
