Source-derived summary

The Battle of Ongjin Peninsula (Korean: 옹진반도 전투; Hanja: 甕津半島 戰鬪) was a series of battles that occurred in Ongjin Peninsula between 25 and 26 June 1950 and was a part of the Operation Pokpung (North Korea) and Operation Western Region (South Korea) that marked the beginning of the Korean War. On 25 June, the Korean People's Army (KPA) 3rd 38-Guard Brigade, reinforced with the 1st Infantry Regiment of the 6th Infantry Division, launched a surprise attack on the Republic of Korea Army (ROKA) 17th Infantry Regiment in Ongjin Peninsula, modern-day Ongjin and Kangryong. The battle ended on 26 June with a KPA victory, but many ROKA troops were able to escape from the peninsula.

Prelude

Ongjin Peninsula lies at the westernmost point of the 38th parallel. It is surrounded by the sea and can only be accessed by land through North Korean territory. Pupo, located at the southernmost point of the peninsula, was the only major supply line for the ROKA. To ensure a safe evacuation, securing Pupo was of utmost importance. The distance between Pupo and Incheon is 90 km by sea, and, at the time, it took 9 hours for a ferry to travel one way.

There are strategic mountains at the centre of the peninsula that can be used to observe the entire peninsula and be used for military encampments. Prior to the battle, the two opposing forces had already had three clashes near these mountains in 1949.

North Korea

Between 10 and 23 June 1950, the KPA completed its deployment for full-scale war in the western region under the guise of military training.

Editorial analysis

Why this record matters

The phrase “1950 part of the Operation Pokpoong in Korean War” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Sep 16, 2026. The linked authority identifier is Q26757. Authority coordinates are 41.766, 129.816. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1950 and 1949.

Critical limits

Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Compare institutional narratives with records created by participants and affected communities. Dates and formal titles are useful anchors, but not substitutes for context.
