Jamestown Line

The Jamestown Line was a series of defensive positions occupied by United Nations forces in the Korean War.

[1] As a consequence, major UN ground operations from late spring—under the direction of Lieutenant General Matthew Ridgway—were primarily conducted to recapture or establish durable defensive lines, including the Wyoming, Missouri, Kansas and Jamestown Lines.

[2] The Jamestown Line stretched from the Imjin River near Munsan-ni then arched northeast 35 miles (56 km) in the strategically important sector of front from the Kimpo peninsula on the Yellow Sea coast to a point east of Kumhwa.

[3] The line was subsequently established during the UN counteroffensive between May and November 1951, just north of the 38th Parallel (38°N) during Operation Commando (1951).

[4] Held by the US I Corps, this sector was just 30 miles (48 km) from the South Korean capital, Seoul.
