The Federal Prosecutor has been examining numerous detailed new leads to a hitherto undiscovered agent network of the former Soviet secret service, the KGB, in Germany. The researchers in Karlsruhe are primarily concentrating on Moscow sources who were taken on by the successors to the KGB and have probably been reactivated since the end of the Cold War.
The basis for the research is extensive information on agents which a Russian defector smuggled into London from the Moscow secret service. After intensive analysis, the British secret service passed all information on KGB connections in Germany to the BfV in Cologne in early 1996.40
In July 1997 another leak from Mitrokhin’s archive occurred in Austria. Press reports quoted a KGB document giving directions for locating a secret arms dump of mines, explosives and detonators, codenamed GROT, hidden in a dead letter-box near Salzburg in 1963, which had been intended for use in sabotage operations:
Leave the town of Salzburg by the Schallmoser Haupstrasse leading to Highway No. 158. At a distance of 8 km from the town limit, in the direction of Bad Ischl-Graz, there is a large stone bridge across a narrow valley. Before reaching this bridge, leave the federal highway by turning right on to a local road which follows the valley in the direction of Ebenau; then go on 200 meters to the end of the metal parapet, which stands on the left-hand side of the road. On reaching the end of the parapet, turn left at once and follow a village road leading in the opposite direction. The DLB is located about 50 meters (60 paces) from the turn-off point leading from the main road on to the village road…41
Though the Austrian press did not mention it, the document came from Mitrokhin’s archive, which also revealed that in 1964 road repair works had covered the entrance to the DLB, raised the ground level, and changed the layout of the surrounding area. The KGB had decided not to try to recover and relocate the GROT arms dump. Attempts by the Austrian authorities to find the dump in 1997 also failed.42 Mitrokhin’s notes reveal that similar KGB arms and radio caches, some of them booby-trapped, are scattered around much of Europe and North America.43
The press leak which came closest to revealing the existence of Mitrokhin’s archive was a further article in the German weekly
