The project was separate from the plans drawn up by Finnish chief of staff officers in the summer of 1944 for the transition to guerrilla warfare.
The SD's Finnish arm was led by Sturmbannführer (Major) Alarich Bross, the Abwehr's by Fregattenkapitän (Commander) Alexander Cellarius.
At the meeting, a resistance movement in accordance with the SD's plans was established under veteran organisation "Front Soldier League".
[3] According to the plan, the leadership of the organization would be in Tallinn, and the liaison committee in Finland would handle communications, transportation and safehouses with the support of the Germans.
The actual armed activity would be carried out by a regional resistance movement, for which the weapons would be obtained from the Germans and in connection with the possible disarmament of the Finnish army.
[3] However, the plan was conditional on German troops remaining in Estonia and northern Finland, which made it impossible to implement.
On 5 September 1944, the 20th Mountain Army Commander, Lothar Rendulic, proposed the establishment of a resistance operation at the German chief of staff.
Until the spring of 1945, the stations kept in touch with the German military intelligence service Sonderabteilung Lappland (Special Department Lapland).
Wilhelm Laqua, head of SD's Kirkenes office and commander of Einsatzkommando Finnland, founded Karesuvanto radio station that operated in October 1944.
[12] Weapons, radio equipment and money received from Germany and Sweden were hidden in Närpes, Vaasa, Helsinki and Hämeenlinna.
After the Germans left Southern Finland in the first week of September 1944, Sonderkommando Nord was established as the governing body of the Finnish resistance movement.
Contact with the Finns lasted at least until April 1945, although the leadership of the resistance movement was already disengaging from German control at that time.
[6] The base came from the German-occupied Kongsvinger fortress in Norway, where Finnish SS men had been trained as group leaders for a volunteer unit from Finland.
There was also a small group of about twenty volunteers from those Finnish women who had moved to Norway and Germany with German troops and were recruited to the same detachment for message training.
[15][16] In January 1945, Major Bross, his political advisers Aarne Runolinna and Cellarius traveled by submarine from Heringsdorf to the coast of Finland in front of Kristinestad to negotiate with the Finnish leadership of the resistance movement.
[17] On January 17, Johan Fabritius, the practical organizer of the movement, and Karl Jansson, a liaison officer and journalist, were transported to the ship.
The nominal leaders of the movement, Carl Lindh and Vilho Helanen, who were invited to the meeting, did not arrive to the chagrin of the Germans.
Bross suggested that a refugee government be established for Finland and that sabotage activities in the war reparations industry be started .
Seppo Heikkilä, who had received intelligence training from Germany and was the former commander of the Navy's Liinahamari patrol ship, took part.
Based on the reports, it would be decided when it would be time to send troops and material with special training from Germany to Finland.
Captain Lauri Törni and Lieutenant Solmu Korpela, who had arrived from Finland, also stayed on board, and had been recruited to train in Germany as trainers for the men of the resistance movement.
[18][19] The ship returned to Heringsdorf without difficulty, and Fabritius and Runolinna prepared a memorandum on the situation in Finland for the headquarters of Sonderkommando Nord.
[21] The resistance movement in Blacknäs, Vaasa, had three large fishing vessels at its disposal, which were well suited for the smuggling of refugees to Sweden.
[22] Through the safehouse routes, the resistance movement transported Finnish Nazis and fascists, officers and intelligence personnel, Estonian and East Karelian refugees and German citizens out of the country.
On the other hand, there were still fears of a Soviet occupation, and the focus of action was on plans to get as many patriotic-minded people as possible into the movement and smuggled into Sweden.
Eleven people were convicted in a treason trial, and the longest sentence, 7 years in prison, was given to Karl Sundholm, who helped Kyrre escape.
Lauri Törni and Seppo Heikkilä trained at Sonderkommando Nord received six years in prison, others shorter sentences.
