3/6/18. In British Generals in the War of 1812 Wesley Turner takes a fresh look at five British Generals - Sir George Prevost, Isaac Brock, Roger Sheaffe, Baron Francis de Rottenburg, and Gordon Drummond - who held the highest civil and military command in the Canadas. He considers their formative experiences in the British Army and on active service in European and West Indian theatres and evaluates their roles in the context of North American conditions, which were very different from those of Europe.
