Dartford's survival hopes have been dealt a blow with Luton recalling striker Alex Wall.
The former Maidenhead forward netted six times in 11 games as the Darts lost only twice with him in their side.
Apart from the Bulls, the Darts were the side in the relegation fight having made the fewest transfers from January up to when the window shut last week.
The Bulls saw no incoming deals, and three players depart - Eric Odhiambo at the expiry of his short term deal, Josh O'Keefe being sold, and Micah Evans' loan expiring.
Dartford brought six players in, extended the loans of four more, and released three. Aldershot brought ten players in, Southport 11, Chester 13, and Tamworth a whopping 18 new faces while shipping a further 13 players out.
