November and December 1916, was a time of change in some leadership positions in World War I. The death of Franz Joseph I, emperor of Austria, topped the list, but the British and French had some significant changes as well.
On Nov. 25, David Beatty replaced John Jellicoe as commander of the Grand Fleet, while Jellicoe became First Sea Lord. Although under Jellicoe’s command, the British had gained a victory at Jutland, Jellicoe was criticized for the cautious way he handled the fleet and his failure to gain a dramatic victory over the Germans.
He would eventually be forced out of a leadership role in the war due to his failure to successfully counter the German U-boat threat.
