After this the brigade continued to advance, moving through Ruddenburg and Greven before carrying out an attack on Osnabruck, which No. 3 Commando led, on 4 April 1945. The next day, they crossed the Weser River in assault boats and under the cover of darkness carried out a flanking manoeuvre on the Germans occupying the town of Leese. As other elements from the brigade attacked from the east, No. 3 Commando, now under the command of Peter Bartholomew after Komrower had been posted to the Commando Training Depot, carried out a follow-up operation to the north. The operation was an attack on a factory that had been producing V-2 rockets and after No. 3 Commando had captured it with the support of a number of tanks, a search found a number of these weapons, along with about 100 scientists who had been working in the factory.
