The Author wrote numerous letters home from the campaigns that he fought with Wellington in the Peninsular when he was commanding his Regiment. He was therefore in a senior position and privy to secrets of the war. He is often caustic regarding his superiors including The Iron Duke himself. He packs his letters with interesting descriptions of the life and his surroundings. Once Waterloo was won and Napoleon defeated and captive, Bingham was selected to accompany him on his journey on HMS Northumberland to final exile at St Helena.. There he remained with his captive until relieved by another officer(Sir Pine-Coffin) in 1818. The diary for this period is full of fascinating descriptions of the deposed Emperor and the habits of him and his staff.
