Japanese Expansion - WW2 Timeline (December 1941 - August 1942)

Not to be out-done by the Germans in Europe, the Empire of Japan enacted their own brand of Blitzkrieg when taking over the Pacific and portions of Asia.

The Empire of Japan knew it had to act fast and in number to complete the sphere of influence its authorities envisioned throughout the Pacific and in Southeast Asia. This meant a rapid and mobile military force with calculating and resource-minded objectives that would help keep air, land, and sea forces humming along like a well-oiled machine.

Carrier warfare was nothing new to the world by the time of World War 2 though tactics and technology regarding its operational use evolved much since the days of The Great War. Aircraft carriers would become the new king of the sea by the end of it all, supplanting the mighty battleship at the top of the pecking order. The surprise attack by the Japanese Navy against the American fleet at Pearl Harbor reaped some initial, albeit limited, results as U.S. Naval activity out of Hawaii was temporarily disrupted. The greatest flaw in the Japanese attack was the American carriers being out at sea, saving these very important battlefield pieces for future use.

On a similar note, the British Royal Navy - now charged with policing the waters making up the Indian Ocean and surrounding regions - were at the mercy of the powerful air arm of the Imperial Japanese Navy. With a limited set of warships in the theater, the Royal Navy did what they could against the calculated assaults of the Empire only to be handed subsequent defeats themselves.

With the battered United States Navy still regrouping and the stretched British Royal Navy reeling, Japanese forces now moved on the islands that made up former European colonies through amphibious assaults forcing the Allies into retreat, surrender, or destruction. At any rate, carrier warfare had proven its worth as both sides began to showcase their floating islands throughout the many campaigns of the Pacific Theater.

The Japanese reach in the Pacific and Asia was at its apex by the end of 1942 as the Allies finally mobilized to take the offensive through an island hopping strategy. Japanese expansion had engulfed tiny Wake Island, the Philippines, Malaya, Burma, the Dutch East Indies, parts of New Guinea, the Caroline Islands, the Gilbert Islands, the Marshall Islands, the Marianas Islands, and some of the Solomon Island chain.

If the Allies were going to act, it would have to be sooner rather than later.
