When Maharaj Singh reentered the Doaba region, Gurmukh Singh helped him contact many influential local men needed for a projected raid on government treasury at Bajvara, near Hoshiarpur. Gurmukh Singh was not present when Bhai Maharaj Singh , along with 20 of his followers, was captured on the night of 28-29 December 1849, but was recognized and arrested from among the crowd that gathered near the civil jail at Jalandhar where the prisoners were later brought to be confined.
