Warlord Games now has their British Rocketeer with horse available over in their webshop.
From the release:
Spread panic in the French lines with the addition of some Rocketeers to your British Napoleonic forces!
As well as using Bombarding Frames to launch rockets through the sky (see below), these missile were also fired along the ground, as depicted with this model.
Rocket Troops were at Quatre Bras and Waterloo (under the command of Captain Wingate) and, although Wellington viewed the rockets’ uncertain behaviour with considerable distaste, he was aware that their 2,000 metre range was acceptable and that they had a distinct demoralising effect on enemy troops receiving these formidable projectiles.
