Okay, so the other comment about this show may be partially right: this is pretty bad; but it sure doesn't represent the best of British tv in the 70s. Perhaps the writer was confusing it with some of his own, homegrown tv: like the Dukes of Hazzard, which was foisted on UK audiences at about the same time as this was airing.
Turpin had its moments - oh and it was nothing to do with Napoleon or the 1800s, either (hence the reason you didn't see any Frenchmen...); it was set nearly a century earlier and Turpin was returning home from the War of the Spanish Succession - same enemy, of course, but then, some things don't change. I believe the series was replaced in the schedules (in the UK) by Robin of Sherwood - that's the one without the American accent.
