British Artillery officer Alexander Cavalié Mercer is most famous in history circles for his detailed account of his experiences leading up to and including the Battle of Waterloo in 1815. Fewer know him as an amateur artist, but Mercer often composed what he called "souvenirs," paintings and sketches of his postings in Europe and North America. While posted in Halifax, Mercer painted nearly 80 watercolours of the area between 1838 and 1842.
