of the people and the organisation of the IRA". Staff officer Percival attended the Staff College, Camberley from 1923 to 1924, which had Major-General Edmund Ironside as its Commandant, where he was taught by J. F. C. Fuller, who was one of the few sympathetic reviewers of his book, The War in Malaya, twenty-five years later. He impressed his instructors, who picked him out as one of eight students for accelerated promotion, and his fellow students who admired his cricketing skills. Following an appointment as major with the Cheshire Regiment, he spent four years with the Nigeria Regiment of the Royal West African Frontier Force in West Africa as a staff officer. He was given brevet promotion to lieutenant-colonel in 1929. In 1930, Percival spent a year studying at the Royal Naval College, Greenwich. From 1931 to 1932, Percival was a General Staff Officer Grade 2, an instructor at the Staff College. The college's commandant was by now Major-General Sir John Dill, who became Percival's mentor over the next decade, helping to ensure his protégé's advancement. Dill regarded Percival as a promising officer and wrote that "he has an outstanding ability, wide military knowledge, good judgment and is a very quick and accurate worker" but added "he has not altogether an impressive presence and one may therefore fail, at first meeting him, to appreciate his sterling worth". With Dill's support, Percival was appointed to command the 2nd Battalion, the Cheshire Regiment from 1932 to 1936, initially in Malta. In 1935, he attended the Imperial Defence College in London. Percival was made a full colonel in March 1936, and until 1938 he was General Staff Officer Grade 1 in Malaya, the Chief of Staff to General Dobbie, the General Officer Commanding in Malaya. During this time, he recognised that Singapore was no longer an isolated fortress. He considered the possibility of the Japanese landing in Thailand to "burgle Malaya by the backdoor and conducted an appraisal of the possibility of an attack being launched on Singapore from the North, which was supplied to the War Office, and which Percival subsequently felt was similar to the plan followed by the Japanese in 1941. He also supported Dobbie's unexecuted plan for the construction of fixed defences in Southern Johore. In March 1938, Percival returned to Britain and was (temporarily) promoted to brigadier on the General Staff, Aldershot Command. Second World War Percival was
