I'm guessing that the report of Winston shooting rabbits at Blenheim on October 7, 1898 may be in error. The Battle of Omdurman, in the Sudan, took place on September 2, 1898. Churchill rode with the 21st Lancers in that battle. He would have had to hurry to get down the Nile, take ship to England, and arrive in time for the bunny hunt.
