Brigadier-General Keswith was an English officer during World War I, stationed in France. Glory-seeking Lucian Rupert Davenport reported to Keswith, who mocked him for being a chemist. Other soldiers reporting to Keswith included Colonel Bullsworth, Major Thompson, and an unnamed private.
Keswith was tall and thin, with a bottlebrush mustache, and wore thick glasses. He operated out of a tent that he used as an office, with a desk made from a barn door and a crate.
