Imjin War

Raising a righteous army On the 13th day, 4th month of 1592, Japanese forces appeared off the coast of Busan, marking the outbreak of the Imjin War. The following day, they captured Busanjin Fortress and then attacked and Dongnae Fortress. Japanese forces under the command of Katō Kiyomasa reached Yeongcheon on the 23rd day, 4th month of 1592 and occupied several fortresses in Andong, Sinnyŏng, and surrounding areas. In early the 5th month of 1592, together with his kinsman Chŏng Taein , he raised a righteous army; approximately sixty men, including Cho Hŭiik , Yi Pŏn , and Chŏng Ch'ŏlli , responded to the call. The group acclaimed Chŏng Taeim as commander of the righteous army, appointing Cho Sŏng and Cho Tŏkki as deputy commanders.

Chŏng Taeim dispatched Yi Pŏn to Kim Yunguk , the magistrate of Yeongcheon who had taken refuge at Myogaksa temple , to request cooperation, and sent Chŏng Ch'ŏlli to Pak Chin, Army Commander of Left Gyeongsang Province, to report the formation of the righteous army. In response, Pak Chin appointed Chŏng Taeim as ambush commander. Thereafter, through Yi Pŏn and others, he persuaded refugees to enlist and recruited approximately 900 righteous soldiers. Chŏng Taeim's forces commenced active operations in early the 5th month of 1592, beginning with the repulse of Japanese troops at Taedong .

Early battles On the 5th day, 7th month of 1592, Chŏng Taeim received intelligence that approximately 300 Japanese troops under the command of a general identified as Mayang had appeared along key routes in the area and were committing acts of plunder in places such as Wach'on . In response, he stationed Chŏng Ch'ŏlli and others in ambush on the slopes of Sŏnghwangdang Beacon Station to monitor enemy movements. He also dispersed his main forces to strategic points along the northern routes and at Tangjisan mountain in preparation for a surprise attack. On the 11th day, 7th month of 1592, when the Japanese troops reached Tangjisan mountain, Chŏng Taeim launched a sudden assault with his concealed forces. The Japanese, taken by surprise, were routed. In this engagement, Chŏng Taeim killed the Japanese commander Mayang and captured spoils of war.

On the 14th day, 7th month of 1592, at Pagyŏn , a key transportation point in Sinnyŏng, Chŏng Taeim joined forces with Kwŏn Ŭngsu, Chŏng Sea, and Hong Ch'ŏlloe to confront another Japanese detachment. At the time, approximately one hundred Japanese soldiers, disguised in Joseon attire and impersonating secret royal inspectors, were moving toward Yeongcheon while committing acts of plunder. The allied righteous forces lay in ambush at Kŏrimwŏn and Yŏŭmdong and launched a surprise attack. The defeated Japanese troops dispersed and retreated toward and Hayang. Chŏng Taeim, together with Chŏng Sea, pursued those fleeing toward Hayang and once again defeated them in the vicinity of Wach'on. In this battle, the allied righteous army killed more than thirty Japanese soldiers and captured long swords, spears, and horses.

Siege of Yeongcheon Following the Battle of Pagyŏn, the Yeongcheon righteous army leaders Chŏng Taeim and Chŏng Sea sought to attack the Japanese forces stationed at Yeongcheon and recapture the fortress. After severing the Japanese lines of communication, the righteous forces developed a plan for the recapture of Yeongcheon Fortress. They requested reinforcements from neighboring counties and assembled their troops at Ch'up'yŏng , the southern plain outside the fortress. Chŏng Taeim joined the allied forces from the northern sector with local militia, encamping at Ch'up'yŏng on the 23rd day, 7th month of 1592, where he conducted military training.

On the 24th day, 7th month of 1592, the allied righteous army at Ch'up'yŏng established a formal military command structure and consolidated approximately 4,000 troops into a unified formation as the Ch'angŭijŏngyonggun . The force was divided into three divisions. Chŏng Taeim was appointed commander of the Center Division, while Kwon Ŭngsu, who had been appointed commander of the righteous army by Kim Sŏngil, assumed command as supreme commander. The righteous army leaders also swore an oath of alliance, pledging to retake Yeongcheon Fortress.

As commander of the Center Division, Chŏng Taeim proclaimed strict military regulations. He publicly announced four capital prohibitions: executing anyone who spread disorder within the ranks, retreated upon sighting the enemy, disobeyed a commander's orders, or abandoned formation during battle. From the 25th day, 7th month of 1592, the allied righteous forces began full-scale preparations for the assault on Yeongcheon Fortress. They adopted fire attack as their principal tactic, procuring brushwood and gunpowder for this purpose, and manufacturing scaling ladders and shields for siege operations. In addition, they deployed a selected detachment of approximately 400 troops to attack Japanese soldiers drawing water outside the fortress, thereby disrupting the water supply within the fortress.

On the 26th day, 7th month of 1592, full-scale combat commenced. Japanese forces sallied out in an attempt at a counterattack but, after engagement, were forced to retreat into the fortress. That night, a monk of Bulguksa who had been held captive by the Japanese escaped and returned to the righteous army camp, reporting that the Japanese planned a general offensive on the following day, the 27th day, 7th month of 1592. In response, Chŏng Taeim, together with Chŏng Sea, proposed dividing the forces into two contingents to meet the anticipated assault. Accordingly, the army was reorganized into units composed of Yeongcheon natives and troops from outside the region, with Chŏng Taeim assuming command of the Yeongcheon contingent. He concentrated scaling ladders at the East and West Gates and assigned a selected detachment of 500 men under Chŏng Ch'ŏlli to be stationed at Mahyŏnsan mountain .

On the 27th day, 7th month of 1592, the allied righteous army launched its final assault on Yeongcheon Fortress. Because the Yeongcheon-born troops under Chŏng Taeim were familiar with the fortress terrain, they attacked the southeastern cliffs, which were difficult to access. In particular, Chŏng focused his attack on the Yŏngyangnamnu Pavilion at the South Gate. The Japanese command responded by opening the gate and sallying forth, while troops inside the fortress provided covering fire with arquebuses. Chŏng Taeim personally urged on his officers and led the charge. After intense close combat, the Japanese forces retreated into the fortress, and Chŏng's troops entered through the South Gate. During this engagement, Chŏng Taeim pursued and beheaded Pŏphwa , the Japanese commande under Fukushima Masanori, who leapt into the Namch'ŏn stream . Following their entry, hand-to-hand fighting ensued within the fortress. When a northwesterly wind arose, the righteous army executed the prearranged fire attack, and many Japanese soldiers were killed in the ensuing blaze and combat. As a result, Yeongcheon Fortress was recaptured.

Siege of Gyeongju After the recapture of Yeongcheon Fortress, the Righteous Army and government forces set Gyeongju Fortress as their next objective. Pak Chin concentrated his troops at Angang, and on the 19th day, 8th month of 1592, Chŏng Taeim joined him there with his forces. At approximately 11 p.m. on the 20th day, 8th month of 1592, after completing a military inspection, the Joseon army advanced toward Gyeongju with Kwŏn Ŭngsu in the vanguard. Arriving at Gyeongju Fortress at dawn on the 21st day, 8th month of 1592, Pak Chin established his command headquarters at Kŭmjangdae Pavilion and ordered that the fortress be encircled from the east, west, and north.

In the initial phase of the battle, the Joseon forces held the advantage. However, Japanese reinforcements that had been lying in ambush at Baengnyulsa Temple and at the local Confucian school joined the fighting, reversing the tide and placing the Joseon army in danger of encirclement. When Japanese troops inside the fortress subsequently sallied out to counterattack, the Joseon forces retreated under pursuit. Chŏng Taeim escaped through the East Gate and withdrew in the direction of Bunhwangsa Temple.

Thereafter, operations to retake Gyeongju Fortress were reorganized under the leadership of Pak Ŭijang, who had been entrusted with command by Pak Chin. On the 7th day, 9th month of 1592, the Joseon army launched a renewed assault on the fortress, with Chŏng Taeim participating in coordination with Pak Ŭijang. An offensive employing (time-fused explosive shells) was carried out, and on the 8th day, 9th month of 1592, the fortress was finally recaptured.

Twenty men attended the gathering, including Sŏ Chaegyŏm and Ch'oe Tongbo of Daegu and Kim T'aehŏ of Miryang, and they took a blood oath, smearing blood on their lips. Chŏng composed an oath poem pledging loyalty together with other Righteous Army leaders. In the spring of 1593, Chŏng was appointed Magistrate of , where the post had been vacant, and in the 4th month he led government troops in battle at Dongnae. On the 4th day, 5th month of 1593, he was promoted to the rank of General for Planning Strategies and appointed Vice Director at the Office of Military Training .

On the 8th day, 6th month of 1593, Chŏng joined forces with Kwŏn Ŭngsu, Army Commander of the Left Gyeongsang Province, and Yi Suil, Naval Commander of the Left Gyeongsang Province, participating as a reconnaissance commander in the Battle of T'aehwajin in Ulsan. He led five successive engagements, during which more than fifty Japanese soldiers were killed and the enemy was driven back to Ulsan Fortress. On the 18th day, 7th month of 1593, he was promoted to the rank of Grand Master for Moral Instruction and appointed Magistrate of Yecheon.
