S5E4: Turning Around a Defeated Army: Field Marshall William Slim, with Dr Robert Lyman MBE

Voted Britain’s ‘greatest general’ by the National Army Museum in 2011, ‘Uncle Bill’ Slim led the XIVth Army from defeat to victory. Dr Robert Lyman tells us about Slim’s strategic leadership.

Field Marshal William Slim (1891–1970) is famous for transforming troops who had retreated almost 1,000 miles through Burma pursued by the Japanese Army into a force that emerged from the Second World War victorious. Whether in defeat – where his leadership ensured his forces maintained their order and discipline – or in the campaign that led to their victory, his men loved him, giving him the affectionate title ‘Uncle Bill’. To have achieved this is all the more remarkable given the diversity of forces under his command. A master of combined and joint warfare, his forces included African, American, British, Chinese, Gurkha and Indian troops, and his ability to integrate air into his campaign predates – but acts as an exemplar for – the relationships needed for the air-land battle.

Admiral Lord Louis Mountbatten stated about our subject that: “Whenever leadership is spoken of or written about, tribute is regularly paid to his supreme qualities as the finest leader of fighting men in the Second World War”. Our guest, Dr Robert Lyman MBE, agrees with this; he is a former officer in the British Army and a renowned author. His books include a biography of William Slim – Slim, Master of War (Constable & Robinson, 2004); a record of the Battle of Kohima (Kohima, 1944, published by Osprey Press, 2010); and, with General Lord Richard Dannatt, Victory to Defeat (Osprey, 2023). Dr Lyman is also a Fellow of the Royal Historical Society.
