Midway
In short
The Battle of Midway was a decisive naval conflict in the Pacific Ocean during the Second World War. It took place in June 1942 and significantly weakened the Japanese Imperial Navy.
In plain words
It was a massive sea battle where the United States defeated Japan. By sinking several important Japanese aircraft carriers, the US changed the course of the war in the Pacific.
A simple example
Imagine two large fleets meeting in the middle of the ocean to fight for control of the surrounding islands. The US used intelligence to surprise the Japanese fleet during this encounter.
Why it matters
This victory stopped Japanese expansion in the Pacific and shifted the momentum to the Allies. It proved that aircraft carriers, rather than battleships, were now the most important weapons at sea.
Easy to mix up
Do not confuse this battle with the Battle of the Coral Sea, which happened shortly before it.
