The Crusaders got off to a terrific start at Longmead Stadium in Kent thanks to a wonderful early performance from Jeremiah Gyebi.
Jake Evans sent a pass into the area in the ninth minute, where Jeremiah Gyebi powered a header home.
After Hungerford's early goal, they lost control of the game. Jack Wood scored two goals in the space of seven minutes.
The first was a good finish inside the box, the second a tap in gift at the back post.
It only took the home side another ten minutes to get a third, this time Joe Turner taking advantage of some sloppy defending.
Right on the stroke of half time Jordan Greenidge who had had a hand in two goals already proved too strong for Hungerford’s defence and made it four.
In the 77th minute Jones put a ball in the box and Jake Evans powered home. Tonbirdge seemed somewhat stunned to concede and a minute later Jake Evans again took advantage of some sloppy play this time by Tonbridge to make it 4-3.
