Image: IWM (Q 728) General Beauvoir De Lisle, GOC 29th Division, in conversation with another General; Mailly-Maillet, 29 June 1916. The British had great success with little bush wars and Colonial scraps during the previous twenty years, but nothing prepared them for an enemy that could hit them in the commercial running of their Empire. The Germans began to fray the million little trade agreements, but it was America, in World War II, that finished it. Roosevelt cut the Empire apart not because of any moral, or high ideal, but simply to open doors for American business.
