I ordered mine direct from Tabletop Gaming here:
https://www.tabletopgaming.co.uk/miniature-games/store/back-issues/miniature-wargames/miniature-wargames-august-2019-issue-436I think the scenarios are trying to be faithful to the battles. But battles are battles, so they are not far off generic Middle Ages combat with some special rules for the circumstances. There's no magic, but you'll need trolls for one of the two scenarios.
They hardly seem like must-haves, but they don't look like toss-offs either.
I have a lot of interest in historical gaming, too, though, so it seemed worth picking up the magazine anyway.
