Not many wars in the 19th century?! You're kidding, right? War of 1812, Franco-Prussian War, US Civil War, Mexican War of Independence, American Indian Wars, Mexican-American War, Texas War of Independence, Spanish-American War, and I'm sure there were quite a few more. Typical English arrogance, you figure just cause a War didn't involve "Great" Britain, it didn't happen.
Just for the record, the guy who said that about there not being many wars in the 19th Century, is actually Polish, not English. And you missed many of the Asian continent orientated wars out on your little list there... just so you know.
