The Imjin War was an invasion of Korea by the Japanese between 1592-1598. Although the Koreans were initially no match for the Japanese armies, the Japanese were eventually driven out thanks to Chinese military assistance and several decisive naval battles.
At the beginning of the war, the Koreans had virtually no firearms. The Japanese, on the other hand, had large numbers of them, and had trained their musketeers to perfection in their own civil wars. As a result, we have a lot of accounts of battles between the two weapons. The results are consistent with what happened elsewhere in the world: the bow was handily outperformed. Like the English, the Korean’s experience with firearms caused them to slowly but completely phase bows out of their armies and replace them with muskets. For a great write-up of this transition, see “A Korean Military Revolution?: Parallel Military Innovations in East Asia and Europe” by Tonio Andrade, Hyeok Hweon Kang, and Kirsten Cooper.
To start with, here are some exerpts from Choi Byonghyon’s translation of “The Book of Corrections”. The Book of Corrections was a collection of memoirs from a Korean minister, Yu Songnyong.
At last, our envoys left for Japan in April 1590 [March 1590 lunar] with Yoshitoshi and others. At the moment of their departure, Yoshitoshi presented His Majesty with two peacocks, a spear, and a sword as a gift. His Majesty ordered the peacocks to be freed in the islands of the Bay of Namyang and the musket to be kept in the armory. This was the first time that Korea came to possess a musket.*
*At first, King Sonjo and his officials and military commanders did not realize the importance of muskets, the major weapon of the Japanese army. That is why the king simply ordered the musket presented by the Japanese envoy to be put away in the state armory. A few years later, however, King Sonjo’s view of the new weapon radically changed. When Minister Kim Ungnam said that bows were superior to muskets in power, the king tried to correct him with this comment: ‘The power of muskets is five times greater than arrows’.
The officer rode on a horse, and two soldiers from the post station walked by him slowly, holding the bridle of the horse. Hiding in ambush under the bridge, Japanese soldiers with muskets shot down the officer from his horse and cut off his head and ran off with it. Upon seeing this, our soldiers lost all their fighting spirit.
After a short while a number of enemy soldiers suddenly emerged and started attacking us with ten or more muskets. The ones hit by the bullets were killed instantly. Yi immediately ordered the archers to counterattack using their bows, but their arrows fell far short of their target.
Han Kukham, the provincial army commander of North Hamgyong province, led the soldiers of the Six Garrisons and met the enemy at the Haejongch’ang warehouse. Our soldiers of the northern province being skilled at archery and horsemanship, and its flat and wide ground good for riding horses, those who were on horseback discharged arrows at the enemy, attacking them by turn from the left and right. Unable to withstand our attack, the enemy retreated to the inside of the warehouse.
By that time, it was already dark. The general opinion was that our troops should rest for the night and continue their attack on the following day, waiting for the enemy to come out. However, Han Kukham would not listen and commanded his army to surround the enemy. Using stacks of grain from the warehouse for their cover, the enemy defended themselves from flying arrows and rocks and simultaneously fired their muskets at our forces. Our troops surrounded the enemy standing close together like the teeth of a comb or stacks of firewood. Therefore, when the enemy muskets were fired, they never failed to hit their targets and, furthermore, knocked down three or four men at a time. So our army at last collapsed.
Six or seven of the enemy took their position at the edge of the river and discharged their muskets toward our fortress. The sound of their muskets was terribly loud and intimidating, and the bullets crossed the river to fall down in the fortress. Some of the longest shots, flying over a distance of more than a thousand paces, fell on the roof tiles of Taedonggwan Hall. Some of them even drove as deep as several inches into the wooden columns of the battlements.
The enemy soldiers with red uniforms approached and saw a small group of our people sitting at Yon’gwangjong Pavilion. They mistook us for our military commanders and, crawling over a sand hill, fired their muskets, hitting two among us. However, because of the long distance, the two were not hurt seriously. I ordered Officer Kang Saik to retaliate with p’yongjon arrows*, protecting themselves with a shield. As his arrows flew all the way to the sandy beaches on the other side of the river, the enemy was surprised and eventually retreated.
* A small arrow so sharp and fast that it was able to easily penetrate armor and helmets.
At midnight of the same day [1592.7.19 lunar], Zhao set out from Sunan and launched an attack on P’yongyang. There was heavy rain, and no guards were seen on the walls of the fortress. The Ming army entered through Ch’ilsongmun Gate, but the roads inside the walls were so narrow and circuitous that it was hard for them to pass through while riding their horses. The enemy soldiers concealed themselves and viciously discharged their firearms at their opponents. The showering bullets hit General Shi Ru and killed him, as well as many of his soldiers along with their horses. Zhao Chengxun finally ordered a retreated, but the Japanese did not chase them speedily. However, some of the soldiers who were in the rear, especially those who were stuck in the mud, were all caught and killed by the Japanese.
The last one is interesting because the Japanese were able to overcome the Chinese soldiers despite the heavy rain.
I will add a few more incidents from the Imjin War in a future post.

[…] the natives with their muskets. Contrast with this post where rain did disable the muskets, and this post where Japanese musketeers were able to do good execution despite a heavy rain. Bad weather it seems […]
On Japanese muskets and rain, I’ve read that the Japanese developed a box made from light wood that could cover the fuse and the lock, protecting it from dampness and rain.
