Over time, Campbell grew discontented with the Old Guard. The organisation was sworn to absolute secrecy of membership, and was divided into cells so that its leadership would be hard to identify. Campbell disagreed with this arrangement, asserting that the uncommunicative nature of its leadership to its members, mostly returned servicemen, was ill-fitting to their nature as soldiers. He believed that without clear authority and direction, the Old Guard would be unable to retain members. Unable to convince the committee to change its administrative strategy, he and John Scott left the Old Guard. A week after Campbell's resignation, he and others from the Old Guard agreed, in mid-February, to form a separate body which would be diametrically opposed to the Old Guard’s secrecy and what they considered its inaction.
