As I recall from a book I read in a British History graduate course, the British engaged in over 200 battles.
I'm not qualified to argue with a History graduate but that doesn't seem very many. Depends on the criteria & what you consider a battle I suppose.
Exactly what the author did - picked only certain battles to talk about in his book. Had something to do with the creation of awards/medals.
Interesting enough, I was just looking at http://www.britishbattles.com/ before I answered H's thread.
Oh, History was my minor


Still, I think British History rocks!
