The Duguay-Trouin-class were the first major French warships built after World War I. They were excellent steamers and proved successful and seaworthy over a quarter century of service. All three achieved 33 knots (61 km/h; 38 mph) on trials and could easily maintain 30 knots (56 km/h; 35 mph) in service. Twenty-year-old Duguay-Trouin could still maintain 27.7 knots (51.3 km/h; 31.9 mph) at her post-war displacement of 10,900 tons.^[1] They were fast and economical, although with a limited range.^[2] The fate of these three ships after the French surrender illustrates the dichotomy within the French armed forces at the time: one ship was interned, then joined the Free French, another twice resisted Allied bombardment and was destroyed, and the third was disarmed at a French colonial port and subsequently sunk.
