SECRET

70th COUNTER INTELLIGENCE CORPS DETACHMENT
APO 461, US Army

26 March 1945

RE: Discovery of Cache of Material and Existence of German Underground Resistance Movement Unit.

1. On 24 March 1945 at approximately 1430 in the city of Dudweiler, Agents of this detachment were approached by Richard Simon, already known as a reliable informant. Accompanying Simon was a person named Fritz Mucke, who told the following story: Mucke that morning had been asked by a Werhmacht Lieutenant in civilian clothes to meet him at a road block between Dudweiler and Saarbrucken at 1430. The two were then to attend a secret meeting of SS men to be held at an undisclosed point.

2. Mucke was instructed to attend the rendezvous as planned. Agents of this Detachment followed him and as he met the German Lieutenant (Wahlster) near a villa on the outskirts of Saarbrucken, apprehended them both. Wahlster was directed and forced to lead Agents of this Detachment to the meeting place. This was found to be an elaborate underground cave, formerly a civilian air raid shelter, the entrance of which had been demolished and for which two well camouflaged entrances had been constructed. The cave consisted of seven rooms equipped with medical supplies, water storage tanks, German Army rations, beds, cooking facilities, SS uniforms, civilian clothing, arms, munitions, and demolition material. Among the arms were three Sten guns, a Luger pistol, a German automatic rifle, and 10 Panzerfausts. Among the munitions were an estimated 350 rounds rifle ammunition, 250 rounds .9mm for Sten and Luger. Demolition material consisted of (estimated) 100-pound boxes of an unidentified substance.

3. The cave was well built into a hillside and had concrete floors, brick or heavily-timbered walls, and electric lights. After exploring the cave, Agents of this Detachment arranged for the placing of a guard and proceededwith the prisoner, Wahlster, to Merlebach, where his interrogation was undertaken immediately. Results of interrogation is the subject of a separate memorandum. Mucke and Simon were returned to Dudweiler by a detail of eight men from a Cannon Company of the 274th Regiment which, as a security measure against possible opposition in force, had accompanied Agents of this Detachment on the mission. It was contemplated that informants Mucke and Simon be interrogated further and that leads uncovered in their interrogations and that of Wahlster be fully developed.

AGENT'S NOTES:

(a) Men from the Cannon Company (274th Regt.) who were present on the mission took possession of all of the weapons (Stens, Luger, Automatic Rifle, and a portion of the ammunition uncovered. The contents of the cave were otherwise undisturbed. There were no evidences of bobby trapping.

(b) This is the first evidence of an underground movement in Germany coming to the attention of this Detachment. Investigation disclosed that membership of this movement consists of SS men, Hitler Jugend and former Wehrmacht, and that special training in sabotage had been given members. It is the opinion of this Detachment that similar "caves" or "cells" exist throughout the Saar.
