Explanation:
400 meters: the 400 meter dash is considered the toughest sprint you can do in track. This event is sprinting one full lap around the track, typically competing against a max amount of 5 other people. This is the last of the sprinting events. 800 meters: the 800 meter run is the shortest run someone can compete.
The answer is Battle of the Coral Sea.
The Battle of the Coral Sea denied the Japanese the opportunity to attack Australia.
The battle was fought between the 4-8th May 1942. It was part of the wider Pacific Theater of the second World War II.
The Japanese Navy plans to launch attacks on Australia were intercepted by US intelligence.
This led the US and the Royal Australian Navy to counter the Japanese Advance.
Tactically, the battle was won by the Japanese since they were able to sink more ships and cause more damage.
However, it was a strategic win for the allies as it was the first time that a major Japanese navy attack was stopped in between the ocean.
After this battle, the Japanese were not able to attack Australian territory throughout the war.
