Guadalcanal. However, it was a six month long battle...with many US losses, then finally a US win. Contrary to popular belief; Guadalcanal wasn't simply a land fight...it was a series of NAVAL battles, in which the US Navy suffered about the same, if not more losses than the Japanese Navy did. Had the USN lost the naval battle, the US Marines on the island would have starved and ran out of ammunition, ultimately losing the ground war on Guadalcanal. As it was, the Japanese ARMY starved and ran of ammunition...and ultimately lost the ground war. However, instead of being wiped out or surrendering (which wasn't going to happen)...they evacuated the island(s), and were transported to other garrisons to continue the war. They were transported by high speed warships (destroyers) under cover of darkness.
