On November 11th 1918, the Great War, the War to End All Wars - now known as World War I - came to, sort of, its official end. The description of being the war to end war was originally believed to be true. Now, of course, it isn't.
The armistice was signed in a railway carriage of Marshal Foch's train in the Forest of Compiègne where Foch, Admiral Sir Rosslyn Wemyss and General Weygand accepted the surrender of the Central Powers.
The true, official end to the war did not happen to the signing of the Treaty of Versailles in 1919, some seven months later. The actual end of the war for the participating countries depended on the country, and the belligerent, in question. In the UK, it stretched until 1924.
