from - Stephan Hunter (author) Wikipedia page
His first fantasy novel, For the Crown and the Dragon, was published in 1994, and introduced a young officer, Taliesin, fighting for the Queen of England in a Napoleonic-period alternative reality, where the wars of Europe were being fought with sorcery and steampunk weapons (airships, clockwork machine guns, and steam-driven trucks called kettle-blacks). The book reviewer Andrew Darlington used Hunt's novel to coin the phrase "Flintlock Fantasy" to describe the sub-genre of fantasy set in a Regency or Napoleonic-era period
