He formed a group called Barlindgjengen (the "Yew Gang"), originally consisting of men from Jar in Bærum.
The mission took place on 31 August 1944, and consisted of blowing up 3,000 litres of gasoline stored at Bygdøy's primary school.
They brought 8 kilograms (18 lb) of plastic explosives, but three of the five were to serve as guards, scattered along the route the saboteurs took to Bygdøy School.
No sabotage damage was dealt, and Aks 13000 nearly lost one saboteur—the first injury sustained during the squad's short history—but the injured saboteur, Reidar Smith, was treated by physician Per Giertsen.
Enge and Røed later returned, hurled six one-kilo loads of plastic over the fence at Vestheim School and managed to blow up seventeen tanks of gasoline.
[6] Enge had to guard a team of seven timbermen who worked in the area, so he did not participate in the actual placing of the explosives.
[8] Enge, who had taken the examen artium in 1942 before joining the resistance movement, took higher education in the United States after the war.
