Just two minutes in, Pilgrim fired past James Warrington and into the bottom corner of the goal to leave Slough supporters contemplating the words 'after the Lord Mayor's show' following Tuesday night's FA Cup win at Gosport - but Slough were soon back on level terms just three minutes later.
Dan Burnell, in a rich vein of goalscoring form at present and the recipient of the September player of the month award before the game, drove forward with the ball and unleashed a left-footed rocket from 25 yards which flew into the top corner, leaving Ryan Pryce with no chance.
After Fleet's promising start, Slough were now in the ascendancy and applied pressure which almost resulted in the home side taking the lead. Ed Smith, also highly influential as Burnell's strike partner of late, did well to hold up play and was unlucky not to be able to lay the ball off to a team-mate on the edge of the box.
Burnell, clearly in confident mood, tried another audacious effort from distance but this time sent the shot well wide, and later was unlucky not to latch on to a clever defence-splitting ball through from David Deeney, Pryce getting down quickly to claim the ball.
An unmarked Smith put a header wide after excellent work from Dom Rhone our wide on the left, but Slough found the second goal their play had deserved on 32 minutes. Burnell was again the scorer, heading Jake Parsons' corner into the net after beating Pryce to the ball.
Parsons, unable to play in the Rebels' fantastic FA Cup run, looked a real threat and was influential in the build-up play which saw Adam Logie played in with a sight of goal, but he poked well wide from the edge of the box.
In the second half, rain disrupted the flow of the game somewhat, but Slough wrapped the game up against a Fleet side which offered little on 57 minutes - Smith scoring a third with a neat finish high past Pryce after good work from Parsons.
Pryce made another double save from Burnell and then Smith after spilling the initial shot, with Slough looking much more likely to add to their lead.
Fleet, including 16-year-old Jack White in attack, battled gamely but the best they had to offer was a flicked effort from Garath Byres which Warrington claimed comfortably, and in the final minute captain Patrick Cox's attempted header at goal came off his shoulder and safely into Warrington's hands.
Slough travel to Leighton Town on Tuesday for another important league game before Saturday's trip to Mansfield.
