'Bullfrog' was a British unrealised plan to retake Akyab island in the Arakan western coastal region of Japanese-occupied Burma by means of an amphibious landing using two brigades of Major General F. W. Festing’s Indian 36^th Division and three brigades of Major General J. M. L. Grover’s British 2^nd Division (October 1943/January 1944).

As a result of the decisions taken at the 'Quadrant' conference in Quebec during August 1943, General Sir Claude Auchinleck, the commander-in-chief in India, decided to consider two alternative amphibious assaults, namely 'Buccaneer' to retake the Andaman islands group, and 'Bullfrog' to retake Akyab island. Success in either of these operations would yield handsome strategic advantages, but Auchinleck prepared 'Bullfrog' as this would remove the Japanese threat to Chittagong and also provide an area on which bases could be built for bombers which could be used to interdict the Japanese lines of communication from Rangoon to central and northern Burma.

The threefold object of the offensive was therefore, firstly, to remove the threat posed to Chittagong by Japanese forces operating from Akyab, secondly, to trap significant elements of Lieutenant General Tadashi Hanaya’s Japanese 55^th Division for destruction by the later stages of the land advance of Lieutenant General A. F. P. Christison’s Indian XV Corps in 'Cudgel' and, thirdly, to provide the Allied forces with advanced bases from which their growing air strength could interdict the Japanese lines of communication deep in southern Burma and so materially improve the chances of the Allied land campaigns in central and northern Burma.

The plan was cancelled in January 1943 for lack of the required landing craft, the required lift being 50,000 men, leaving 'Cudgel' to be fought on its own.
