In March 1912, he signed on amateur terms for Southampton of the Southern League, making his debut in a 1–0 victory over Plymouth Argyle on 30 March. On his debut, he laid on the game's only goal for Percy Prince. The local daily paper, The Echo, reported that "Dawe was decidedly plucky to 'get in it'." Dawe always took the field wearing spectacles and one of his lenses was broken during his debut game.
