Worth watching

If you can access the BBC i-player:

AJP Taylor on How Wars Begin

This is no-nonsense history.  Unlike modern BBC telly historians, there are no gimmicks - no dressing up, no striding about medieval castles, no half-baked reconstructions.  And all the better for it.

And if you really want to indulge yourself, you can watch England being thoroughly tanked by The Barbarians here or here.
