Clive Allen's side played their part in a cracking match at Leyton Orient but ended up on the wrong end of a narrow defeat to Portsmouth.
Goals from Charlie Daniels (pictured) and Adel Taarabt gave us a half-time lead before we were pegged back after the break to leave us contemplating a second successive Barclays Reserve League South defeat.
It was entertaining from the start as the visitors created the best of the early openings, but both Gael Nlundulu and Djimi Traore failed to covert free headers.
Once we had weathered the early storm, we started to become the better team and a spell of pressure mid-way through the half led to our opener.
Hossam Ghaly had glanced a header wide from David Hutton's corner shortly before hitting the post with a well-taken left-foot shot on the half-hour mark.
A moment later, we were in-front when Taarabt's quickly-taken free-kick was drilled into the bottom right-hand corner from the edge of the box by Daniels.
But the lead did not last long as Pompey nicely worked a free-kick to Richard Duffy on the right who crossed for the unmarked Tom Kilbey to nod home on 34 minutes
From that point until the break, a half-time lead was anyone's for the taking, and it was us who got our noses in-front.
We had a scare on 40 minutes when Andre Blackman's fierce shot hit the bar, but three minutes later, Taarabt's effort from the edge of the box took a deflection off a defender to send it past the wrong-footed Jamie Ashdown.
At the other end, we had Cesar Sanchez to thank for keeping our first half lead intact when the Spaniard tipped Jerome Thomas' shot round the post in the last action before the break.
But despite starting the second half brightly with good chances falling to Daniels and Hutton, Pompey were the more clinical in-front of goal and it paid off for them
Saying that, Cesar did his utmost to keep out what turned out to be the equaliser on 65 minutes with a fantastic double-save from Kilbey after Little's cross, but Nlundulu eventually slammed home the rebound.
And five minutes later, the Kilbey and Duffy combination worked wonders for the visitors again as the latter's cross was headed home by the striker to give Pompey the lead for the first time.
We had opportunities in the last 10 minutes but Taarabt hit the bar after being released by Daniels in the box, and the latter's cross also just evaded Alex Olsen with the goal gaping as our chance of taking a point when begging.
