After the outbreak of war with Japan the squadron was redeployed to Burma. At this point it was made up predominantly of personnel from other Commonwealth countries, particularly personnel from the Royal Australian Air Force (RAAF), and was commanded by a Rhodesian, Wing Commander Reginald Stidolph, DFC. It arrived in Burma on 7 January 1942 and immediately participated in the first allied bombing attack on Bangkok. A second raid was undertaken on 24 January. The squadron suffered heavy casualties while attacking Japanese columns in Burma and the survivors withdrew to Calcutta in March. From Assam, No. 113 bombed Japanese communications and airfields. At least 16 RAAF personnel were killed in action with the squadron as a Blenheim unit in Burma and India.
