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.

In this episode we discuss Admiral Katsu Kaishū’s transformation of the modern Japanese navy into a force that defeated the Russians in 1905.

For 200 years, Japan was largely isolated from the world. By the 19th century, as countries in Europe and North America were expanding into its neighbourhood, Japan’s military capability had atrophied. In response, the Tokugawa Shogunate created a navy in 1853 and Katsu became a naval officer. Trained by the Dutch, he became an expert in Western gunnery and commanded the Kanrin Maru on the first deployment of a Japanese warship to a Western port. There he could observe how a Western navy worked – ideas he brought back to Japan as the basis for the modern Japanese Navy.

By 1867, under the Meiji government, he was responsible for overseeing the Navy’s transition from sail to steam technology. He introduced profound changes to the Navy’s organisation, strategy and tactics, including shore-based defences, harbours, shipyards and human resource systems that allowed access to the talent needed by a more technological service. Ultimately, the foundations he laid helped the Japanese defeat the Russian Navy at the battle of Tsushima in 1905.

Commander Dr Hiroyuki Kanazawa, our first guest for this episode, serves in the Japanese Maritime Self-Defense Force, and his PhD examines the Japanese Navy in the Late Tokugawa Period (1853–1868). Dr Haruo Tohmatsu, our other participant, is Professor of Diplomatic and War History at the National Defense Academy. His PhD in Politics and International Relations is from the University of Oxford. He has published numerous works in English, including Pearl Harbor (London: Cassell, 2001) and World War Zero: The Russo-Japanese War in Global Perspective, vol. 2 (Leiden: Brill, 2006).

Lieutenant General George Flynn describes how his friend and former boss General Gray, the 29th Commandant, transformed the US Marine Corps’ warfighting, ethos and capabilities.

General Alfred Mason Gray Jnr (1928–2024) was not the most obvious choice to lead the US Marine Corps when he became its 29th Commandant in 1987, but he succeeded in transforming the Corps into one of the world’s premier fighting forces. He moved the Corps’ culture and ethos towards one that prioritised manoeuvre warfare, in which all Marines became warfighters first and foremost. His changes included new processes and equipment, but were primarily focused on the human – a conceptual transformation as much as it was a transformation of capabilities. He embraced the indirect approach from Basil Liddell Hart (Season 2 Episode 10) and John Boyd (Season 1 Episode 7), as well as William Lind’s thinking on dislocating adversary decision-making that was so effective in the 1991 Gulf War, yet he situated these inside the Marine Corps’ traditions and values.

Lieutenant General George Flynn (retd) served in the US Marine Corps for 38 years, including as General Gray’s aide in 1989–1991, as Chief of Staff at Special Operations Command and as Deputy Commander Multinational Corps Iraq, and created the Joint Force Development Directorate at the Joint Chiefs of Staff. Now on the Board of Regents at the Potomac Institute, he is also a member of the Council on Foreign Relations.
