Prelude
The battle occurred after North Korea began a sustained campaign to redraw the maritime boundary line – known as the Northern Limit Line (NLL) – between the two Koreas. On 6 June 1999, North Korea's state-controlled Korean Central News Agency (KCNA) claimed that the "sea boundary line" had been violated by South Korean warships that had illegally trespassed in the North's territorial waters. The following day, three North Korean patrol boats and thirteen fishing boats belonging to the North Korean Navy (KPN) crossed the NLL off Yeonpyeong. The South Korean Navy (ROKN) responded by sending five fast boats and four patrol ships in a bid to prevent the North Koreans from crossing the NLL. On 8 June, seven North Korean patrol boats and seventeen fishing vessels repeatedly crossed the NLL between 05:55 and 23:20 local time. Twelve South Korean fast boats and four patrol ships were deployed and South Korean fishing boats were ordered to leave the area. The South Korean military issued a directive ordering a "bold response" to North Korean provocations, while stressing the need to uphold the rules of engagement. The first physical confrontation occurred on 9 June, when six North Korean patrol boats and five fishing boats crossed the NLL again. As on the previous day, the South Koreans deployed twelve patrol boats and four patrol ships. At 06:35, a North Korean patrol boat collided with a South Korean fast boat, causing minor damage. The South Korean Ministry of National Defense issued a statement calling on the North Koreans to desist. Further clashes occurred the following day when South Korean fast boats confronted four North Korean patrol boats that were accompanying a group of twenty fishing boats. The South Korean government decided at this point to use force to oppose further crossings of the NLL.Main clash
The battle began on the morning of 15 June. The North Koreans had twenty fishing boats south of the NLL, which were joined at 08:45 by four patrol boats. The patrol boats began attempting to "bump" South Korean fast boats. At 09:04 they were reinforced by three North Korean torpedo boats which joined in the "bumping offensive". The South Koreans again outmanoeuvred the North Koreans and began ramming them, hitting six North Korean vessels in theAftermath
The North Koreans retreated to their side of the NLL by 11:00 and ceased crossing the line. Although military tensions on the Korean peninsula escalated for a while as a result of the battle, no further conflict resulted at that time. Despite the severe losses suffered by its navy, the North Korean government claimed victory; KCNA asserted that "more than ten enemy battleships were either burned or severely damaged and they had no alternative but to flee, taking many dead bodies and remnants with them." Minor incidents and incursions concerning fishing in the area have since continued, including another naval skirmish in 2002 known as the " Second Battle of Yeonpyeong" and another in 2009 known as the " Battle of Daecheong". In November 2010, North Korea attacked Yeonpyeong itself.Notes
