Problem: Sahara:

Problem: Pacific War:

After the Allied setbacks in 1943, the South East Asia command prepared to launch offensives into Burma on several fronts. In the first months of 1944, the Chinese and American troops of the Northern Combat Area Command (NCAC), commanded by the American Joseph Stilwell, began extending the Ledo Road from India into northern Burma, while the XV Corps began an advance along the coast in the Arakan Province. In February 1944 the Japanese mounted a local counter-attack in the Arakan. After early Japanese success, this counter-attack was defeated when the Indian divisions of XV Corps stood firm, relying on aircraft to drop supplies to isolated forward units until reserve divisions could relieve them.
