This is a recording from 02 August 1890 made by one of the surviving trumpeters (Landfrey) of the famous British Light Brigade that charged the Russian batteries at the Battle of Balaclava in October of 1854 in the Crimean War. He sounds the bugle call that was sounded that day, using a bugle from the battle of Waterloo in 1815.
It gave me chills. I don't know how it will affect you.
