Invasion of Hawaii (Days of Infamy)

The Invasion of Hawaii began on December 7, 1941 when the Japanese bombed Pearl Harbor. By December 14, they captured the island of Oahu. The largest and deadliest battle throughout the invasion was the Battle of Pearl Harbor, where Japanese forces attempted to take the Naval Base from the remaining American soldiers there.

By January 6 1942, Japanese forces would have pushed the American forces off the island of Hawaii, the largest island in the Hawaiian Islands. Most fighting was over by mid-January.

Background
The possibility of a war between the United States and Japan had been known since the 1920s, but tensions began to grow seriously after Japan's 1931 invasion of China. Japan stopped their expansions into China after this, but both countries knew war was inevitable. After the Japanese invaded French Indochina in 1940 did tensions grow again. President Roosevelt moved the American Pacific Fleet from San Diego to Pearl Harbor, Hawaii in early 1941 and also ordered for a military buildup in the Pacific in case Japan made another move against American interests.

After the Japanese expansion in Indochina, the U.S ceased oil exports to Japan. This was seen as an act of war, and started making plans to invade the oil-rich Dutch East Indies. The Japanese knew that an invasion of the Dutch East Indies would lead to a war between Japan and the western nations, the United States included. This would lead to the Japanese planning for a strike directly at the American Pacific Fleet in Hawaii. The Japanese knew that just a strike at the fleet wouldn't be enough to damage the overall United States military in the Pacific and would just give the American people a reason to fight, so they started planning for an entire invasion of Hawaii, and eventually, the continental United States

The Japanese Task Force left their port, under strict radio silence, on November 26, 1941.

Attack on Pearl Harbor
Around 7:25 AM Hawaiian Time, a U.S army radar picked up on an incoming fleet of aircraft. In OTL it was believed to be scheduled incoming B-17 bombers, but in this ALT, the massive size of the fleet makes the radar operators realize that a massive aircraft fleet is coming to bomb Pearl Harbor, and alert the naval base. Due to this, much more aircraft and anti-air guns are ready, and much more sailors are, at the very least, are awake.

At 7:48 AM Hawaiian Time, Japanese planes bombed Pearl Harbor. The first wave, compromised of 183 planes, began attacking their targets. Some american planes were able to take off in time and had engaged in dogfights against the Japanese in the skies.

The Second Wave, compromised of 171 planes,
