On this day in 2015, Ross Hannah scored two goals in three minutes as Town earned a comfortable win over Aldershot.
Hannah latched on to Craig Disley's through ball and lifted the ball over Phil Smith to put the Mariners ahead.
The striker lobbed Smith for his second shortly after, and Jon-Paul Pittman extended the lead to three by firing in from 12 yards out after the break.
Jordan Roberts's powerful free-kick cut the deficit late on, but the Shots were unable to threaten the Mariners thereafter.
Town were already assured of a play-off spot before the game, and would now face Eastleigh for a place in the play-off final.
