The Battle of Coral Sea is called the modern battle of 1942. It was the first battle in World War II, where the ships didn't even catch a glimpse of eachother.
During the first week of 1942, American spy planes observed a huge force of Japanese ships in the Coral Sea. An air battle was already waged due to the interception of Japanese planes by American forces. This battle was resumed on May 7th, in the Coral Sea.
The American carriers Yorktown and Lexington were under orders to intercept the Japanese fleet. Under orders, 93 torpedo-bombers took off and spotted the 4th Japanese fleet. Fierce fighting erupted, and the Americans managed to sink seven major vessels. The Japanese carrier Ryukyi, four cruisers and two destroyers. Three cruisers, three destroyers, and a carrier were also damaged.
The Americans lost the Lexington, one destroyer, and one tanker. The Americans and Japanese withdrew from Coral Sea at the same time, but even though it was a double retreat, the Americans were starting to slow down the Japanese expansion.
In only a time of six months, the Japanese now controlled 3,000 miles of ocean. They also controlled millions of square miles of land, with millions of people under their control. The Japan also recently occupied Attu and Kiska, which could pose a threat for a land invasion in Alaska or North America.
The Japanese now controlled the following: The Philippines, Burma, Dutch East Indies, and Singapore. The Battle of Coral Sea was the only thing close to a victory over Japan. Somebody had to stop them... but who?
