Field Marshal William Joseph Slim, 1st Viscount Slim (6 August 1891 – 14 December 1970), usually known as Bill Slim,"No one called him William" . was a British military commander and the 13th governor-general of Australia from 1953 to 1960.
Slim saw active service in both the First and Second World Wars and was wounded in action three times. During the Second World War he led the Fourteenth Army, the so-called "forgotten army" in the Burma campaign. After the war he became the first British officer who had served in the Indian Army to be appointed Chief of the Imperial General Staff.
In the early 1930s, Slim also wrote novels, short stories, and other publications under the pen name Anthony Mills.
Early years William Slim was born at 72 Belmont Road, St Andrews, Bristol, the son of John Slim by his marriage to Charlotte Tucker, and was baptised there at St Bonaventure's Roman Catholic church, Bishopston. He was brought up first in Bristol, attending St Bonaventure's Primary School, then St Brendan's College, before moving to Birmingham in his teens. In Birmingham, he attended St Philip's Grammar School, Edgbaston, and King Edward's School, Birmingham.
After leaving school, his father's failure in business as a wholesale ironmonger meant that the family could afford to send only one son, Slim's older brother, to the University of Birmingham, so between 1910 and 1914 Slim taught in a primary school and worked as a clerk in Stewarts & Lloyds, a metal-tube maker.
First World War Despite having no other connection to the university, in 1912 Slim joined the Birmingham University Officers' Training Corps, and he was thus able to be commissioned as a temporary second lieutenant into the Royal Warwickshire Regiment on 22 August 1914, on the outbreak of the First World War; in later life, as a result of his modest social origins and his unpretentious manner, he was sometimes wrongly supposed to have risen from the ranks. He was badly wounded at Gallipoli. On return to England, he was granted a regular commission as a second lieutenant in the West India Regiment.
In October 1916, he rejoined the Royal Warwickshire Regiment in Mesopotamia. On 4 March 1917, he was promoted to lieutenant (with seniority back-dated to October 1915). He was wounded a second time in 1917. Having been previously given the temporary rank of captain, he was awarded the Military Cross on 7 February 1918 for actions in Mesopotamia.
Evacuated to India, he was given the temporary rank of major in the 6th Gurkha Rifles on 2 November 1918. He was formally promoted to captain and transferred to the Indian Army on 22 May 1919.
Interwar career Slim became battalion adjutant with the 6th Gurkha Rifles in 1921.
On 1 January 1926, he married Aileen Robertson, daughter of Rev John Anderson Robertson (d.1941) minister of Cramond near Edinburgh. They had one son and one daughter. Later that year Slim was sent to the Staff College, Quetta. On 5 June 1929, he was appointed a General Staff Officer, Second Grade.
On 1 January 1930, he was given the brevet rank of major, with formal promotion to this rank made on 19 May 1933. His performance at Staff College resulted in his appointment first to Army Headquarters India in Delhi and then to Staff College, Camberley, in England (as a General Staff Officer, Second Grade), where he taught from 1934 to 1937. During this period, he also wrote novels, short stories, and other publications under the pen name of Anthony Mills, in order to further his literary interests, as well as to supplement his then modest army salary.
He attended the Imperial Defence College in 1937. The following year he was promoted to lieutenant colonel and given command of the 2nd Battalion, 7th Gurkha Rifles. In 1939 he was briefly given the temporary rank of brigadier as commander of his battalion. On 8 June 1939, he was promoted to colonel (again with temporary rank of brigadier) and appointed head of the Senior Officers' School, Belgaum in India.
Second World War East African Campaign On the outbreak of the Second World War, Slim was given command of the 10th Indian Infantry Brigade of the 5th Indian Infantry Division and was sent to Sudan. He took part in the East African campaign to liberate Ethiopia from the Italians. Slim was wounded again in Eritrea. On 21 January 1941, he was hit when his vehicle was strafed by Fiat CR.42 fightersLewin 1999 p.68 during the advance on Agordat.
Middle East Recovering from his wounds but still unfit for active service, Slim was temporarily employed on the General Staff at GHQ in Delhi. He was involved in the planning for potential operations in Iraq where trouble was expected. By early May 1941 Slim had been appointed Brigadier General Staff (chief staff officer) to Edward Quinan the commander designate for operations in Iraq, arriving in Basra on 7 May. Not long afterwards, Major-General Fraser, commanding the 10th Indian Infantry Division, fell ill and was relieved of his command, and Slim was promoted to take his place on 15 May 1941 with the acting rank of major-general.
He led the Indian 10th Infantry Division as part of Iraqforce during the Anglo-Iraqi War, the Syria–Lebanon campaign (where the division advanced up the river Euphrates to capture Deir ez-Zor), and the invasion of Persia. He was twice mentioned in dispatches during 1941.
Burma campaign
In March 1942, Slim was given command of Burma Corps, also known as BurCorps, consisting of the 17th Indian Infantry Division and 1st Burma Division. Slim was made acting lieutenant general on 8 May 1942. The corps was under attack in Burma by the Japanese and, heavily outclassed by the more mobile and flexible Japanese, was soon forced to withdraw to India. On 28 October 1942, Slim was appointed a Commander of the Order of the British Empire (CBE).
Slim then took over XV Corps under the command of the Eastern Army. His command covered the coastal approaches from Burma to India, east of Chittagong. He had a series of disputes with Noel Irwin, commander of Eastern Army and, as a result, Irwin (although an army commander) took personal control of the initial advance by XV Corps into the Arakan Peninsula. The operations ended in disaster, during which Slim was restored to command of XV Corps, albeit too late to salvage the situation. Generals Irwin and Slim blamed each other for the result, but in the end Irwin was removed from his command, and Slim was promoted to command the new Fourteenth Army—formed from IV Corps (United Kingdom) (Imphal), XV Corps (Arakan) and XXXIII Corps (reserve) – later joined by XXXIV Corps. On 14 January 1943, Slim was appointed a Companion of the Distinguished Service Order (DSO) for his actions in the Middle East during 1941. The American historians Alan Millet and Williamson Murray described Slim as:
Slim quickly got on with the task of training his new army to take the fight to the enemy. His basic premise was that off-road mobility was paramount: much heavy equipment was exchanged for mule- or air-transported equipment, and motor transport was kept to a minimum and restricted to vehicles that could cope with some of the worst combat terrain on Earth. The new doctrine dictated that if the Japanese had cut the lines of communication, then they too were surrounded. All units were to form defensive 'boxes', to be resupplied by air and assisted by integrated close air support and armour. The boxes were designed as an effective response to the tactics of infiltration practised by the Japanese in the war. Slim also supported increased offensive patrolling and night training, to encourage his soldiers to lose both their fear of the jungle and their belief that Japanese soldiers were better jungle fighters. He also instructed them to hold their positions once outflanked.
The Chin Hills formed a natural defensive barrier into Burma, which Slim would have preferred to outflank by an amphibious operation by landing further down the coast of Burma, but demands of the war in Europe meant the necessary landing craft were not available, forcing Slim to devise plans for advancing into Burma overland through the Chin hills. At the same time, the Japanese 15th Army, which formed the main striking force of the Burma Area Army, had grown from four divisions at the beginning of 1943 to eight divisions by the end of 1943 as the Japanese made preparations for invading India, which increased the difficulties of an overland advance into Burma. By 1943, the Burma Railway, which cost the lives of thousands of prisoners of war who built it, was finished; this allowed the Japanese to reinforce the Burma Area Army, and made invading India possible.
As Slim went about training his men for the rigours of jungle warfare, he clashed with Brigadier Orde Wingate, who took away some of Slim's best Gurkha, British and African units for his Chindit raiding group. Slim argued against the loss of his better units to Wingate, and maintained that though Wingate had a successful career in Palestine and Ethiopia he would discover that the Japanese were a considerably tougher foe than the Palestinians and the Italians that Wingate had hitherto been fighting. However, Slim did approve of Wingate's plans for aid to the hill tribes of Burma. The various hill peoples of Burma such as the Kachins, Karens, Chin, Nagas and the Shan collectively amounted to about 7 million of Burma's 17 million people, and unlike the Bamars, who had welcomed the Japanese as liberators, had stayed loyal to the British when the Japanese invaded. The hill peoples of Burma had suffered under Japanese rule, and were more than willing to wage guerrilla warfare against them. Slim approved of the plans of the SOE and OSS to provide arms and training to the hill tribes as a way to tie down Japanese forces that would otherwise be deployed against him.
At the start of 1944, Slim held the substantive rank of colonel with a war substantive rank of major-general and the acting, then upgraded to temporary, rank of lieutenant-general. In January 1944, when the Second Arakan Offensive was met by a Japanese counter-offensive, the Indian 7th Infantry Division was quickly surrounded along with parts of the Indian 5th Infantry Division and the 81st (West Africa) Division. The 7th Indian Division's defence was based largely on the "Admin Box" formed initially from drivers, cooks and suppliers. They were supplied by air, thus negating the importance of their lost supply lines. The Japanese forces were able to halt the offensive into Arakan but were unable to decisively defeat the allied forces or advance beyond the surrounded formations.
In early 1944, the Japanese Prime Minister, General Hideki Tojo, approved of plans for victory in Asia, calling for two operations, Operation U-Go as the invasion of India was code-named and Operation Ichi-Go which was intended to defeat China once and for all. The two operations in India and China were closely linked given that American supplies for China were flown over "the Hump" of the Himalayas and the Japanese wanted to take the Indian province of Assam in part to close the American air bases in India that sustained China at the same time that they were launching Operation Ichi-Go, the biggest Japanese offensive of all time, involving 2 million men. The Japanese knew that they lacked the logistics to invade India, and the plans for U-Go were based on the assumption that the British Fourteenth Army would just collapse, allowing the Japanese 15th Army to capture enough food to prevent its men from starving to death. Following the Japanese 15th Army into India was the Indian National Army commanded by Subhas Chandra Bose, an ardent nationalist. The Japanese believed that the mere presence of Bose in India would inspire the men of the Indian Army to mutiny and murder their British officers, and set off an anti-British revolution that would allow the Japanese 15th Army to take all of India.
