Good idea. Here's one such encounter:

Of course, the Brits did have some supporting arms - artillery, naval bombardment, light tanks etc - but not in sufficient numbers to avoid the infantry doing most of the work.

Diversionary tactics, attacking at night, overwhelming weakly defended spots, covering fire etc all played a role, although in the end a lot of it seemed to come down to grit and determination (symbolised by the fixed bayonets).
