Saints scored four tries as they beat the British Army 24-10 in the Mobbs Memorial match at Franklin’s Gardens on Wednesday evening.
Lewis Ludlam, Jordan Onojaife, Gareth Denman and Sion Bennett all dotted down in front of more than 3,000 supporters.
Flanker Ludlam started things off in the seventh minute as he profited from a strong Saints maul.
The Army then had a try disallowed, but registered a penalty to cut the gap to two points.
Saints conceded a try on 18 minutes, but, six minutes later, lofty lock Onojaife made the most of huge pressure on the Army line to score.
Saints scored again just before the break as prop Denman popped up to score out wide.
And there was to be only one try in the second half, with No.8 Bennett doing the business to put the game beyond the Army.
Saints: Furbank (Dingwall 44); Packman, Hutchinson, Williams (Emery 40), Collins (Strachan 58); Grayson, Duchesne; E Waller (Beesley 36), Fish (Rayment 66), Denman (Parkins 40); Moon (Cardall 58), Onojaife; Paterson (c) (Harrison 40), Ludlam, Bennett.
