Both schools had to contend with extremely challenging conditions in Belfast, with the final played in a driving rain, with a cold wind whipping around the stadium.
Despite the 2.30pm kickoff, the rain fell so heavily that the game had to be played under the floodlights.
The opening exchanges saw both sides opting to keep the ball in tight with their respective packs, although both backlines did attempt to make use of the big Kingspan pitch by kicking into space, and raining down box kicks.
Wallace High School eventually broke the deadlock after an attritional opening period, with the first try of the final coming in the 18th minute.
A series of strong carries by the pack drew the Lisburn school to within a few inches of the line, and it was loosehead prop Daniel Macklin-Copeland who drove over from close range to send them 5-0 clear.
Inside centre Quinn Armstrong slotted his conversion, and Wallace's 7-0 lead looked decisive in a game where points would be hard to come by, largely due to the awful weather.
Towards the end of the opening half, Wallace extended their advantage and scored what would prove to be the final points of the game.
The backs showed great hands and managed to string together a few slick passes which carved open the Campbell defence.
It once again put Wallace close to the Campbell line, and it was Macklin-Copeland who again showed great strength and composure to power over for his second try just before the break.
The second half saw Wallace embedded in their own territory for the majority of the period, as they had to deal with relentless waves of Campbell attack.
Wallace defended well, and had moments on the front foot through the impressive carries of tighthead prop Rio McDonagh - but the Belfast school kept Wallace largely confined to their own half.
Despite keeping Wallace under pressure for long periods, Campbell were unable to make a decisive breakthrough.
On two occasions they managed to charge down kicks from the Wallace defence, but one chance ended with a knock-on, and the other saw Wallace scramble to clear away the danger.
Despite the clock ticking away, Campbell kept hunting a try to narrow the lead, and found themselves camped in the Wallace 22 in the last moments of the game.
However, Wallace continued their resolute defence to the very end, and hung on to claim victory and secure the 2022 Danske Bank Schools' U16 Cup.
