Could anyone provide me with some info on hand grenades used in the period ca. 1790-1820? I have seen a couple mentions of grenades in use during the Napoleonic era (primarily in naval warfare), but I don't know anything serious about them. I'd be especially interested to know details on the materials and variations used. For example, were all grenades in this period made of iron, or is there any evidence of other materials (e.g. pottery, glass, etc.) used to construct them? What about different variations on grenades (e.g. smoke bombs, incendiary devices, etc.)? Also, if there's been any literature written on hand grenades during the 18th and early 19th century, I'm up for recommendations!
