Hmmm - I wasn't really close, but I was close enough for them to engage on fire-at-will. I'd assumed this meant they were close enough to be pretty effective, but I'll do as you suggest and use them at closer range next time. (Actually, I still have the save-game, I may be able to re-fight this battle.)
