Which medieval weapons were easier to learn, and which ones were more difficult?
A long spear / pike in a band is probably the simplest weapon we can use properly. Pointy bit towards the enemy, stay close to your friend, and whatever you do, do not run or we will all die.
The Welsh longbow is very heavy. It takes years of hard practice and we can still tell the skeletal structure of the archer today because of the defects it has in the skeletal system – like this good chapter.
The weight of his bow was 200lb. That’s like picking up a big man, especially with your arms. Modern bows are probably 50lb and often have the help of machines to reduce that further.
