Tuesday's 3-1 victory at Charlton was by some distance Pompey's best away win of the season - and arguably the most important for a number of reasons.
The fact that this was a game in hand against a bottom end rival, following measly back-to-back defeats cements this as a critical result in the context of Pompey's fight for at least another campaign in English football's second tier.
As the final whistle blew, the players' reaction told you just what an incredibly significant night it was.
Sensational full-time scenes for the 2,500 travelling faithful and the drive home felt like an absolute breeze.
It could easily have been a wholly different story had Nicolas Schmid's outstretched leg not prevented Harry Clarke within the first minute of the game.
What followed was the best 55 minutes we've had on our travels for quite some time.
Three goals all different in nature, fortuitous for the first, pressure penalty for the second and a memorable Terry Devlin special for the third.
The Northern Ireland international is almost a guarantee for player of the season for me.
Ebou Adams has brought a completely fresh face to Pompey's midfield and we had the most we've seen so far from the mercurial Gustavo Caballero.
It almost felt like we got a little giddy at 3-0 and went on to do things we might not otherwise have done had the game been a stalemate.
An hour in, perhaps the neutral would have had Pompey favourites to secure the points, yet those that bleed blue could not relax, knowing full well we've all read similar scripts many times before.
Nathan Jones was quoted post-match saying the away side wanted it more than his players. That will be music to every Pompey fan's ears around the world.
A point from either Millwall or Wrexham and John Mousinho's side will have had a good week on the road.
Anything more than that and relegation concerns might just start to abate for now.
