The highest ranking officer was a Capt. In Aug 50 he heard a radio broadcast made by a Major

PWs dressed in fatigues. They were fed three times a day with insufficient rations of bread, sugar, cooked rice and given cigarettes.

PW heard that there were from 400 to 700 US PWs in middle of Aug 1950. PW believes that the PENJANG PW Camp may be moved further inland because of intense bombing.

1. 105th Tank Div

Organized at PYONGYANG in Apr and May 47 and was called a tank regiment. Later became the 105th Tank Brig. As soon as the war started, this unit advanced to SEOUL and was designated as the 105th Tank Div.

Organised at SEOUL as soon as NK captured SEOUL.

This unit was called the 3 (00th Unit. Mission was to guard and protect all factory and government property in KYONGIDO area.

This Brig was guarding the 38th parallel before the war. As soon as the war started, it was designated as the 9th Div and moved to TAEGU area. Approx strength when it became the 9th Div was 10,000.

Weapons: 36 (76mm & 122mm) guns in 9th Div, unknown number of recoilless 76mm guns.

Composed of 3 Inf Regts and 1 Arty Regt. 3 Inf Bns and 1 Mortar Co in each regiment. The Arty Regt in each Div received its designation from the division designation. (EX: 107 Div. 107 Arty Regt).

The following were directly attached to the, 9th Div Hq: Me■ Bn, Transportation Bn, Communication Bn, 76mm Recoilless Arty Bn and AT Arty Bn (45mm).

4. 2nd Div.

This unit was organized at CHINNAMPO and initially designated as the 4th Inf Brig. As soon as war started, the Brig advanced to SEOUL, became the 2nd Div.

PW observed the 38th parallel defenses near KAESONG. PW believes that, the 38th parallel is well fortified. Trenches were dug in the mountains and there are concrete pill boxes. There are barbed wire entanglements, mines are planted in front of the trenches.

The mountains at KAESONG, overlooking the road from SEOUL to PYONGYANG, and at YONPYONG, overlooking the road from SEOUL to WONDAN, and at PUPYONG and YANGYANG were well fortified.

The pill boxes and trenches weft constructed on the side of the mountains facing the road so that the road would be covered from any direction.

PW observed the following border security Unit near 38th parallel:

3rd Ind Brig (later became 9th Div) at CHUCHON

7th Ind Brig ( 〃 7th Div) at SIBYON RI

1st Ind Brig ( 〃 8th Div) at KANSONG

The 38th parallel line was divided into three sections. The west section included the area from CHANGHYON to YESONG river and was under the 3rd Ind Brig which had its Hq in SIBYON RI. The area from MANSEGYO RI to the east coast was under the 1st Ind Brig which had its hq in KANSONG.

These brigades advanced to South KOREA as soon as the war started and became divisions, and the vacant posts were taken over by three newly organized border security battalions.

PW believes that the NK troops in the southern front will fight until the end though they might not be able to put up a good fight because of their tremendous losses of weapons and personnel. PW also thinks that they will attempt to defend the 38 parallel.

PW believes this war to be a struggle between Communism and Democracy not a war between North and South KOREA.
