So the two handed sword is indeed a daunting foe for a housebreaker, but the shorter Gladius & Shield is more useful in tight confines.
Or there is the little two foot long child's baseball bat, a truly lethal weapon.
For intruders, I'd prefer the hatchet I have on the shelf above my bed (yes, it's in a sheath bolted to the shelf. Yes a cat once,
once, knocked it down onto my pillow right next to my head, hence the bolt).
I don't have a shield*, and if I have to take someone in the hall to my bedroom, I wouldn't want a shield, it's cramped enough as it is in there.
* I mean, I don't have a
real shield. I have some boffer shields which are foam and canvas on a frame, in a duffle, in a closet, stored... I guess if the attacker had a knife or bat it might help. A second hatchet or maybe a baton would be better for me, though I do have a cane beside my door, but it's collapsible. And I've never really liked using shields†, my actual combat training was with bare hands and polearms... so... my hatchet-fu isn't exactly topform either.
† With a shield I tend to forget to use it actively, it just mostly hangs around. I have used small bucklers, and I do well(ish) with them, but again, I'd rather just have an off-hand weapon. I'm far more active with paired weapons than sword and board. But you want to see actual skill? Give me a duelling glaive, quarter/bo staff, or naginata. I've trained with those and half-assed kept up on my katas (until I blew out my knee last thanksgiving).
