Aldershot's unbeaten run of eight games was brought to an end by Crawley Town.
The Shots came close to taking a first-half lead but Danny Hylton saw his low drive go inches wide.
Michael Doughty scored the vital goal, cutting in from the right to unleash a left-footed drive that went in off the far post.
The Red Devils had chances to double their advantage late on but substitute John Akinde failed to hit the target with two close-range efforts.
VIEWS FROM THE DRESSING ROOM
Aldershot manager Dean Holdsworth told BBC Surrey:
"We were up against a good side today and we gave a good account of ourselves.
"I'm not going to fault them too much because we've had a hell of a week. We've had a hell of a lot of football for the size of the squad.
"We've had a lot of emotions and sometimes that can drain you. Towards the end of the game we looked a little bit tired, we looked ready for a sparkle and we never got it."
Crawley Town manager Steve Evans told BBC Sussex:
"It just shows you what what Crawley Town can do with a half-reasonable squad to choose from.
"We were decimated for a couple of weeks, and the numpties and the nuggets up and down the country wrote us off. But we refused to listen to them and knew what was right and what was wrong.
"On another day some of our strikers might have got themselves a hat-trick as a substitute. We've beaten a good side today, you only need to look at their record."
