Unlike the Japanese, who killed their own wounded, Slim went out of his way to ensure good medical care for his wounded and to evacuate via the air his wounded to hospitals in India. Slim knew his men would fight better if they knew that they would receive the best possible medical care under the conditions if they were wounded. On 8 August 1944, Slim was promoted to lieutenant general, and, on 28 September 1944, he was appointed a Knight Commander of the Order of the Bath (KCB). In December 1944, during a ceremony at Imphal in front of the Scottish, Gurkha and Punjabi regiments, Slim and three of his corps commanders (Christison, Scoones and Stopford) were knighted by the viceroy Lord Wavell and invested with honours. Slim was presented with his insignia as KCB, and the others with their KBEs. Slim was also mentioned in despatches. By the end of 1944, the majority of the men serving in the British 14th Army were in fact not British as of the 12 divisions that made up the British 14th Army, 2 were British, 7 were Indian and 3 came from Britain's African colonies. In addition, there were six Chinese divisions, two regiments from the U.S. Army and various tribal militias made up of Shan, Chin, Naga, Kachin and Karen peoples raised by the OSS and the SOE fighting on the Allied side in Burma, requiring Slim to play the role of the diplomat as much as a general to hold these disparate forces made up of so many different peoples together.
