World War 1 supreme commander Gen. Foch visited Hotel Imperial in 1923 and signed the VIP guest book.

On 11 November 1918, Foch accepted the German request for an armistice. Foch advocated peace terms that would make Germany unable to pose a threat to France ever again. His words after the Treaty of Versailles, "This is not a peace. It is an armistice for twenty years" would prove prophetic; the Second World War started twenty years and sixty-five days later.
