One Medieval weapon I know little about is
The Bow and Arrow. I found an interesting read here at ~
https://en.wikipedia.org/wiki/English_longbow
The report opens with Quote" The English longbow was a powerful medieval type of longbow (a tall bow for archery) about 6 ft (1.8 m) long used by the English and Welsh for hunting and as a weapon in medieval warfare. English use of longbows was effective against the French during the Hundred Years' War, particularly at the start of the war in the battles of Sluys (1340), Crécy (1346), and Poitiers (1356), and perhaps most famously at the Battle of Agincourt (1415).
They were less successful after this, with longbowmen having their lines broken at the Battle of Verneuil (1424), and being completely routed at the Battle of Patay (1429) when they were charged before they had set up their defensive position." Unquote.
It is an excellent report on The English Longbow...which to some is a bit of a misnomer since it tends to be associated with Welsh Bowmen... but interestingly if the Bow was Yew it presumeably came from France in ships carrying another fine French product...Port !
but I would not suppose it could be called a French Bow
The above reference on Range says Quote"
The range of the medieval weapon is not accurately known, with much depending on both the power of the bow and the type of arrow. It has been suggested that a flight arrow of a professional archer of Edward III's time would reach 400 yd (370 m) but the longest mark shot at on the London practice ground of Finsbury Fields in the 16th century was 345 yd (315 m).
In 1542, Henry VIII set a minimum practice range for adults using flight arrows of 220 yd (200 m); ranges below this had to be shot with heavy arrows. Modern experiments broadly concur with these historical ranges. A 667 N (150 lbf) Mary Rose replica longbow was able to shoot a 53.6 g (1.89 oz) arrow 328 m (359 yd) and a 95.9 g (3.38 oz) a distance of 249.9 m (273.3 yd). In 2012, Joe Gibbs shot a 2.25 oz (64 g) livery arrow 292 yd (267 m) with a 170 lbf yew bow. The effective combat range of longbowmen was generally lower than what could be achieved on the practice range as sustained shooting was tiring and the rigors of campaigning would sap soldiers' strength.
Writing 30 years after the Mary Rose sank, Barnabe Rich estimated that if 1000 English archers were mustered then after one week only 100 of them would be able to shoot farther than 200 paces, while 200 would not be able to shoot farther than 180 paces".Unquote
In a contemporary account it goes on to describe viz
by Gerald of Wales commenting on the power of the Welsh longbow in the 12th century: One of the men of arms was struck by an arrow shot at him by a Welshman. It went right through his thigh, high up, where it was protected inside and outside the leg by his iron chausses, and then through the skirt of his leather tunic; next it penetrated that part of the saddle which is called the alva or seat; and finally it lodged in his horse, driving so deep that it killed the animal.
