William Brown's autobiography is a unique historical document, since he is the only memoirist to have come to light from the ranks of the 45th (1st Nottinghamshire) Regiment of Foot for the period of the Peninsula War – a regiment that was one of Wellington's longest-serving and most valiant in that turbulent era, a proud member of Sir Thomas Picton's ‘Fighting' Third Division. William was born in Kilmarnock in 1788, the son of a poor cobbler, but seems to have been given a good education since the narrative is clear and lively, with many learned literary references. Like many young men, William Brown originally volunteered into the militia, Britain's second-line army intended for home defence only. And like a goodly percentage of these young men, he found that the life more-or-less agreed with him, and willingly took the bounty on offer to volunteer into the regular army a few weeks after Wellington's victory at Talavera.
