Originally published in 1837 in two volumes, this is the 1845 edition which combines both into one handy volume.
It is the account of Norbert Landsheit, late sergeant in the York Hussars and 20th Light Dragoons, who saw service in the Peninsular War. He related his military life to the Rev. George R. Gleig, whom he met whilst an inmate at Chelsea Hospital in London, where the Gleig was rector at the time.
Landsheit had an amazingly long career, and his memoir provides a fascinating insight into the experiences of a German soldier within the British Army.
