In May 1943, promoted to acting Brigadier, Kindersley was appointed Commanding officer of the 6th Airlanding Brigade.

[1] It was on his recommendation that Major John Howard and D Company 2nd Oxfordshire and Buckinghamshire Light Infantry (the 52nd) were selected to lead the coup de main operation at Pegasus Bridge and Horsa Bridge before the Allied invasion of the Normandy beaches began.

He was one of the figures who, as both a Bank of England director and a financier with private interests, was suspected of having taken advantage of advance warning of a change in Bank Rate to sell gilt-edged securities ahead of the public announcement of the rate change.

Although subjected to intensive and aggressive questioning by the Solicitor General Reginald Manningham-Buller during the proceedings, he was fully exonerated in Lord Justice Parker's subsequent report in what journalists at the time suspected of a whitewash.

[3] Kindersley was chairman of the Officers Association from 1946 to 1956, Honorary Colonel of 10th Parachute Battalion from 1947 to 1952 and High Sheriff of the County of London in 1951.

When sent by night to support the advance to the railway line west of St. Python, his platoon captured an obstinately defended machinegun post.
