== Listing order == 

 When I created this article, I replicated the order given in my source, which was also more or less the order the actual riders rode in, and seems to represent some kind of rough order of precedence. This has been changed to an apparently random order with no discussion. For instance, riding immediately side by side with George V were his uncle the Duke of Connaught and his cousin the Kaiser. Now the Kaiser is listed after all the foreign kings and Connaught somewhere towards the bottom of the list. On what grounds?
