Operation Minden was an offensive undertaken by United Nations Command (UN) forces during the Korean War between 8–12 September 1951, as part of a general advance to extend the Wyoming Line, the UN Main line of resistance. Operation Minden was the precursor to the much larger Operation Commando, which established the Jamestown Line.

Background

By the autumn of 1951, US

Chorwon. However, the curvature of the Imjin River, north of the small town of Choksong, meant that there was a salient extending southwards into the line.^[1]

As part of an overall strategy to seize territory in order to strengthen his army's defensive position US

General James Cassels; the 28th British Commonwealth Brigade, the 29th British Commonwealth Brigade and the 25th Canadian Infantry Brigade.^[1]

Operation

The 28th British Commonwealth Brigade, including the 1st Battalions of the King's Shropshire Light Infantry and King's Own Scottish Borderers as well as 3rd Battalion, Royal Australian Regiment (3RAR), crossed the Imjin River and established a bridgehead on 8 September.^[3] Corresponding moves were made by flanking South Korean and United States units.^[4]

The initial movement of the 28th Brigade was met with little resistance, with the exception of some minor skirmishing on the 3RAR front, during which three prisoners were captured.^[3] With the bridgehead secure, two bridges were quickly erected by I Corps engineers, with one bridge situated at the river crossing of the northerly road from Choksong.^[1]

The 29th Infantry Brigade and the 25th Canadian Infantry Brigade moved out of the bridgehead on 11 September. The 29th advanced to the northwest, while the Canadians moved off to the north. The 28th Brigade remained in reserve, guarding the newly constructed bridge. Like the 8 September crossing of the Imjin River, the movement of the 29th Brigade met with little resistance, although there were light casualties (12 killed) due to artillery fire.^[3] The Canadians completed their movements with no casualties.^[4] The operation concluded on 12 September, with the front line now running across the arc of the Imjin River, and firmly established nearly five kilometres north of the river.^[2]

Aftermath

There was some further adjustment of the line which was not completed until 14 September.

Royal 22^e Régiment, mounted offensive operations in order to seize some hills held by the Chinese, during which three Canadian soldiers were killed and ten wounded.^[1] The new front line was now much closer to the Chinese outposts than previously, necessitating regular patrols. Around 1,500 civilians also had to be evacuated from the area.^[3]

The successful implementation of Operation Minden led to the more large scale Operation Commando, which involved a substantial part of I Corps. Operation Commando was launched in October 1951 and resulted in the establishment of the Jamestown Line.^[4]
