The Japanese arrived at Jinju on 20 July 1593 with 90,000 troops with reinforcements from Japan. 
The Japanese began on 21 July 1593. First they destroyed the edges of the dikes surrounding Jinju to drain the moat, then they advanced on the fortress with bamboo shields. The Koreans fired on them and repelled the attack.
On 23 July the Japanese tried again with siege towers, but they were destroyed by cannon fire.
On 25 July the Japanese were able to successfully mine a section of the outer wall under mobile shelters.
On 27 July the Japanese attacked the weakened area of the wall, and with the aid of a rainstorm, was able to dislodge its foundations. The fortress was quickly taken.
Like after most Japanese victories in largely populated areas, there was a massacre. The Japanese report more than 20,000 heads being taken, more than all the combatants on the Korean side, while Korean records state 60,000 were killed, essentially the entire population. The Japanese then retreated to Busan.
