On this week's Mentioned in Dispatches podcast, Tim Halstead discusses the connections between London schools and the Territorial Force during the Great War. While the contribution of Public Schools to the Officer Corps is well known, this talk focuses on the less-explored role of Grammar Schools. Drawing on Rolls of Service from both school types in and around London, Halstead sheds light on their strong links to specific regiments and their wider wartime influence. This talk was part of the London Pride Conference held in June 2024.
