An own goal from Daniel O'Shaughnessy would start the rout in the first half before goals from Kyle Bennett, Gareth Evans, Jamal Lowe and a Kal Naismith double was enough to start the party at a packed out PO4.
Now five years on, the Blues remain in League One with none of the members from that squad still in Danny Cowley’s side.
We take a look at the 18-man squad from that day and where they are now.
Read through to see where some of those forgotten names are.
17. Jamal Lowe
Lowe joined Pompey that January and netted the two goals which sealed promotion at Notts County. The winger would endure a successful two years with the Blues before moves to Wigan and Swansea followed. After a surprise move to Bournemouth last summer, the 27-year-old was recently promoted to the Premier League with the Cherries. Photo: Harry Murphy
18. Nicke Kabamba
Joining with Lowe, his Pompey career was a lot shorter lived than his former team-mates. He was late sent out on loan to Aldershot that summer before joining Havant and Waterlooville the following year. Spells at Hartlepool, Kilmarnock and Northampton would follow and is currently on loan at National League side Woking. Photo: Joe Pepler
