well, a bear or gorilla is going to hit that shield hard enough to shatter every bone in your arm/shoulder, so not a great deal of help there
And if you stand still to let it hit you, you deserve it!!

You're not using the shield to make an impenetrable brick wall, here. The impact might turn the shield, or you might deflect it, but you don't stand there to try and take it full on.
A beer or a gorilla is not going to stand there and knock at your shield while you choose your moment to attack back, they will knock you over.
If you're going to just stand there and let it hit you, you're doing it wrong.
As I explained, it is a barrier. A movable barrier.
With all due respect, this is also why I would assume anyone choosing a particular medieval weapon would do so either because they know how to use it properly, or because that hypothetical choice would come with the knowledge of its use included.
Used properly you can stop blows before they reach full force, deflect blows, choke up opponents, distract, attack, control and direct them... even non-human ones, as I often prove with my dog and a cushion.
a shield is useless when your flat on your back.
Even laid over you, it is still a barrier your enemy must get past to reach you and a weapon you can use to attack.
The whole thread is about fighting it in a life or death situation, i think for this argument we can assume it wont run away after a backhand
It's life or death for you. It is still an animal and will behave like one. Hit it hard enough or well enough and it will run screaming like a little girl.
But if you don't like that reality then hit it once and rock it's brain. Then as fast as you can hit it again and again and again and again and again and again and again and again and again and again and again and again and relentlessly bash it's head senseless, whereupon you may thrust it in its gut and make a Skywalker Sleeping Bag out of it.
If you're THAT desperate and the thing has murder in it's eyes, then you have to be more violent than it.
You have to Prison Rush it, basically, at which point weapon of choice isn't desperately important anyway.
Just because you can get lucky with a fatal 1 ina million hit, doesnt mean it is clever to choose something that does little damage
It's a lot more common that one in a million.
You clearly have no idea how much damage even a blunted metal training sword can do.
You clearly have no idea how much damage even an untrained person can do, especially when stressed.
You clearly have no idea how much damage a person can do by accident.
It's also very easy to use a sword in basic attacks. Swordspersons just know how to use them a lot better.
Firing can mean the act of discharging any weapon, fire does not necessarily need to be involved.
The grammatically correct term is shoot, not fire.
I doubt you've ever parted a cake in half, but have always cut it... You don't assimilate a book, you read it... you don't drive a bike or pilot it, you ride it.... same thing here.
As much as a hobbiest archer may like to believe, a 75lb drawn arrow is not going to do any significant damage without hitting the right spot.
Depends on the arrow and especially the point. Hunting broadheads of certain types would rip that bear hide wide open and a maille bodkin would punch a nice deep hole.
Incidentally, a well-published 1990 experiment with a 68lb longbow shooting a 2.5oz arrow, and a 740lb cranequin crossbow shooting a 1.25oz bolt... measured both weapons shooting their projectiles at around 135fps.
So same speed, but the longbow arrow is heavier as well, so carries more penetration. An 80lb warbow would put an arrow a good 9" through plate armour, so a 75lb one wouldn't be far off that. But then, there's a wealth of articles and YouTubes on the whole thing already, so don't just take my word for it.
Due to the thickness of hide and flesh, using a bow to kill these big things would be wishful thinking.
So they're thicker and tougher than plate steel, are they?
Physics called - He says you're wrong.
The article i quoted earlier in the thread recommends Crossbow with minimum draw of 200lb.
See comparison above between 68lb longbow and 740lb crossbow. Nuff said!
I will take 1 or 2 steel plate, hole-punchingly powerful crossbow bolts over a few 70lb shortbow shots when shooting to kill.
I'll take as many plate bodkin, maille bodkin and other such proven hole-punchingly powerful longbow arrows as I can shoot in the time I have available... which is more arrows with heavier punching weight, hence the whole reasoning of more wounds on the target = more death.
You might get lucky and hit one eye. In that same time I can hit an eye and a liver and a lung and a heart and maybe even another eye. I can likely afford a miss or two, as well.
Get wedged in between ribs or other bones and a big strong target flailing around and that weapon becomes useless to you
It's a sharp cone. It doesn't get wedged.
And if you do manage to get it between the ribs, great - Twist it around and cause more pain and more damage.
