Anton Muttukumaru

After returning from England, in 1934 he joined the Ceylon Defence Force, a part-time reserve force raised by the British to defend the island. Muttukumaru was commissioned as a second lieutenant in the Ceylon Light Infantry (CLI) on 11 September 1934. In 1939 he was mobilised with the rest of the CDF at the outset of World War II. During this time, he would go on to command the CLI Guard at the South East Asia Command headquarters in Kandy and was promoted captain on 29 November 1940 and major in 1942. On 1 November 1943 he was promoted lieutenant colonel and appointed commanding officer, 2nd Battalion CLI, in which appointment he continued to serve until the general demobilisation which took place after the end of the war in January 1947. He led Ceylon's contingent in the London victory parade in 1946.[2]

Following the war, Muttukumaru worked once again as a lawyer representing the Attorney General, in a variety of cases but soon gave up law to function as Officer in Charge, Administration in the Ceylon Defence Force Headquarters, where he assisted in the initial plans for the formation of a new Ceylon Army, including the drafting of the Army Act.[2]

When the Ceylon Army was formed in 1949, he was one of three lieutenant colonels commissioned into the regular force with the serial no O/50001. There he served as the Chief of Staff to Brigadier the Earl of Caithness. During this time he attended the Senior Officers' School, where he was taught by Field Marshal Montgomery and befriended future Israeli Defence Minister, Brigadier Moshe Dayan. He led the Ceylon contingent of soldiers to London on ceremonial duties for the funeral of George VI in 1952, and for the Queen's coronation. There his men mounted guard at Buckingham Palace. He was subsequently attached to the British Army in West Germany, serving at the Headquarters of the British Army of the Rhine.[2]

On 1 January 1954, he was promoted to the rank of colonel and took over as commanding officer of the 1 Battalion, Ceylon Light Infantry and Officer Commanding Troops, Panagoda. Under his command the battalion undertook its first live fire exercise Ex TYRO. On 19 July 1954, he was appointed aide-de-camp to the Queen. On 8 February 1955, he relinquished command of the Ceylon Light Infantry.

On 9 February 1955, he was promoted to the rank of Brigadier and appointed first Ceylonese Army Commander. This took place while he was at attending the Imperial Defence College, Colonel Wijeyekoon who was the chief of staff, served as acting army commander until his return in 1956 when he assumed command of the army. On 1 January 1958, he was promoted to the rank of Major General, becoming the first army officer to hold the rank. During his time as commander, the army grew in size and was deployed on several occasions to curb civil unrest and riots. He elevated the Army Recruit Training Depot at Diyatalawa to the Army Training Centre, raised a new infantry battalion, Ceylon Sinha Regiment, promoted all commanding officer to the rank of lieutenant colonel after elevating all regular units to regimental strength; established the Headquarters of the Ceylon Volunteer Force and initiated the concept of regional commands. In 1959, he decided to retire so that younger officers could have their chance to command, even though Prime Minister Solomon Bandaranaike asked him to stay on.[2][3]
