History of the Harquebus
Harquebus:
The Tanegashima/Hinawajū is a Matchlock rifle, Introduced to Japan in 1543 through the Portuguese. The gun itself resembles an early American musket. When Japan tried to copy the locksmith gun, an issue arose surrounding the barrel and the fitting of the bises bolt tightly. This put a delay on the ability of Japanese forces to utilize the weapon. The situation was solved when the Portuguese ship returned, and the smith taught the Japanese the technique needed to mass produce their guns. The Tanegashima is very heavy, awkward, and large compared to that of the modern bows at the time. They had other issues along with reduced agility while wielding one, like getting jammed in rainy or muddy conditions. Along with these issues, the bow and arrow could shoot far faster than the Tanegashima, with almost 15 arrows to one bullet. There was a 5 step process to shoot the weapon, first gunpowder was placed at the bottom of the barrel, next a bullet was jammed in, with more gunpowder was added to the pan (matchlock firing system), and finally the trigger is pulled, igniting the powder and shooting the bullet. The maximum range was around 80-100 meters, and towards the end of that range, the bullets would do little against body armor.
