The war in the Aleutions is also an interesting topic. The Japanese held Attu and Kiska. We invaded Attu over the beach, 7th Inf. Div and 4th Inf. Regiment. Winter combat in May of 1943, included hand to hand, bayonets and human wave suicide attacks. Just like the fighting in the South Pacific. The weather was as bad an enemy as the Japanese. We also invaded Kiska, but it had been evacuated under the cover of weather. The AL Can was to be a Main Supply Route for that front should it have happened.
