During World War II, Japan was involved in several major battles, including the Battle of Midway in 1942, where they faced a significant defeat that shifted the balance of power in the Pacific. The Battle of Guadalcanal (1942-1943) was another critical confrontation, marking the first major Allied offensive against Japanese forces. Additionally, Japan participated in the Battle of Iwo Jima (1945) and the Battle of Okinawa (1945), both of which were pivotal in the Allies' island-hopping campaign leading to Japan's eventual surrender.
The major battle after the Battle of Antietam was the Battle of Fredericksburg, fought from December 11 to December 15, 1862. This battle saw the Union Army, led by General Ambrose Burnside, facing off against Confederate forces under General Robert E. Lee. The Union suffered significant losses due to poorly coordinated assaults against well-entrenched Confederate positions, resulting in a decisive Confederate victory. This battle further solidified Lee's reputation as a formidable military leader.
