After the Berlin Olympics, Bowden-Smith, now a
lieutenant colonel, became Commanding Officer of the 16th/5th Lancers at
Secunderabad in India, but when the regiment began to convert to a light tank regiment, he returned to the UK in 1938 to take up a newly created post of Superintendent of the Army Equitation Centre and Remount Depot at Weedon. When
World War II broke out, Bowden-Smith was Inspector of Remounts, becoming Inspector of Cavalry in 1940. On 6 September 1941, Bowden-Smith was appointed Brigadier commanding
125th Infantry Brigade in
42nd (East Lancashire) Infantry Division. The division was scheduled to become an armoured division, and 125th Brigade officially became
10th Armoured Brigade on 1 November 1941. Based at
Barnard Castle, the brigade consisted of three battalions of the
Lancashire Fusiliers (1/5th, 1/6th and 9th), which became
108th,
109th and
143rd Regiment Royal Armoured Corps respectively. As an armoured brigade in the cruiser role, 10th also had a motor infantry battalion (13th
Highland Light Infantry) under command. However, 10th Armoured Brigade left
42nd Armoured Division in May 1942, the motor battalion was withdrawn, and on 25 July the brigade was redesignated 10th Tank Brigade. The role of a tank brigade was infantry support, so the brigade moved to the '
Dukeries' area of Nottinghamshire, where RAC units trained with infantry tanks. Bowden-Smith had his HQ at
Carlton-in-Lindrick with the regiments dispersed to
Thoresby Hall,
Welbeck Abbey and
Rufford Abbey. On 17 October 1942 the brigade was placed under the command of
48th (South Midland) Division. This was a reserve formation, and 10th Tank Brigade was given the role of holding and training reinforcements for other tank units. The brigade maintained Lancashire Fusilier traditions, marking Gallipoli Day on 25 April and celebrating
Minden Day on 1 August 'in traditional style. Each unit held a ceremonial parade and march past'. When rumours began to circulate in August 1943 that 10th Tank Brigade was scheduled for disbandment, Members of Parliament for the Lancashire towns complained about the loss of their TA battalions. but shortly afterwards the impending disbandment was confirmed and the brigade came under direct
War Office control. Bowden-Smith left on 6 October 1943, and the Brigade HQ and regiments disbanded in November. Bowden-Smith was now posted to
Delhi to join the staff of the new
South East Asia Command (SEAC) under Admiral
Lord Louis Mountbatten. He served on SEAC staff until 1946 when he retired. ==Later life==
