Over time, the group's operations evolved into more elaborate acts of defiance targeting specific German collaborators, such as the Fuchs Construction Company. This construction company was a well-known German collaborator in Aalborg. In February 1942, the group decided to target this company, as they saw it as a symbol of the Danish government's compliance to German occupation. Located at the Aalborg airport, the company's headquarters were separated from the terminals and runways, so the boys decided to show resistance by setting it on fire. Meeting outside the
Aalborg Monastery, the boys planned the act of sabotage in the nighttime. Once they arrived at the airport, they made it through inspections without raising suspicion. They were able to make their way to the site of the construction company, continuing through the countryside. After a few miles of walking, they arrived to where the Aalborg hangars were located, and where they found wooden decoys of animals, placed by the Germans to create a false impression to those flying overhead that they were travelling over farmlands rather than an area of significant military presence. The airport was important to the Germans, as it served as a place for refueling during the invasion and
occupation of Norway. Although there was a manned guard outside the main entrance of the airport, the Fuchs office was left unguarded, as it was off to the side from the airport. The boys present, Eigil, Helge, Børge, and Knud, then cut through the wired fence and then smashed through the windows with a stick. They were then able to go through the windows, finding them inside of the Fuchs office. Here they came across rows of desks, one of which supported a pile of cards that read "You have been visited by a member of the Nazi party." Overlooking all of these desks was a large photo of Adolf Hitler, which the boys then removed from the wall and smashed over a desk, causing glass to go everywhere. The boys then took turns dancing on the portrait in order to further deface it. Then gathering all the drawings, receipts, and business cards they could find, on top of the smashed portrait, placing a pillow on top of the pile and setting it ablaze. After lighting and tossing the match, the boys ran for their bikes. Although the building did not burn down entirely, this was their first large-scale sabotage. In a Churchill Club meeting following this attack, Eigil, Helge, and Børge told the rest of the group what they had done. The other boys in the group stressed that they felt as though they had made a mistake by not taking credit for the act of sabotage, as the Germans could then diminish it to an attack by common criminals rather than Danish patriots. So, the group took a sledgehammer to a levelling machine they had stolen from the office, wrecking it before writing a message on it, reading "Get out of our country, you stinking Nazis." A few nights later, they rode their bikes back to the site of the fire, to return the ruined machine with the message and their signature in order to take credit. == Symbol ==
