The goals of the allied powers in this battle was to defend and set up an ambush to cripple the Japanese fleet. This was made possible because code breakers broke the code of the Japanese communication, and had intercepted a message depicting an attack on midway, and what ships would be there.
The Japanese were going with a 3 pointed attack; Aircraft coming from the NW, a battleship behind the carries, giving most of the heavy firepower, and then forces coming from the S.W. and were not expecting naval forces until later.
