A lock of mane from Copenhagen, the horse that the Duke of Wellington rode into battle at Waterloo, was on sale at a fine arts auction in Cambridge yesterday. Copenhagen not only carried the Duke to victory against Napoleon in 1815, but was also ridden to the door of 10 Downing Street when Wellington became Prime Minister in 1828. Far from cuddly however, he reportedly tried to kick Wellington in the head as he gave him a post-battle pat. When he died at the grand age of 29 he was given a funeral with full military honours.
