First of all it brought to an end a miserable losing steak stretching back eight matches. Secondly, it proved that Halifax do have the bottle and the stomach for a fight.
And, perhaps most importantly of all, it went some way to repairing some of the confidence that has taken such a battering this season.
And the good news is that Halifax thoroughly deserved their success against a Westcombe Park side missing some of their regular first team players.
Indeed, the margin of victory was just reward for a mammoth effort in testing conditions.
Another factor to throw into the mix was the shortage of bodies. Westcombe Park were able to name a full complement of seven replacements allowed in the EDF Energy National Trophy competition, while Halifax only had 18 players on duty in total - injuries and unavailabilities hitting them particularly hard.
A torturous journey to Orpington was made worse by the weather conditions which included incessant driving rain and a strong, swirling wind.
It was vital that Halifax established a half-time lead, no matter how slender, as they were forced to contend with the worst of the conditions in that opening period.
And it was mission accomplished - the 8-3 advantage providing the platform for Halifax's superior pack to totally dominate after the interval.
It was refreshing to see the Halifax forwards establish such a dominance having themselves been bullied on occasions this season.
It was always going to be a war of attrition given the conditions and both sides set about the task with commendable enthusiasm while young referee Richard Kelly also acquitted himself well given that the elements would make for a gruelling encounter.
Needless to say both sides made handling errors as keeping hold of the ball proved pretty difficult.
It took until the midway point of the first half for Halifax to register the first points their wholehearted approach merited, the forwards again moving forward with some aplomb from a scrum and recalled No 8 Richard Brown plunging over.
Joe Knowles teed up the first of a host of difficult conversions which drifted wide on a gust of wind.
The hosts cut the lead within minutes. Dominic Moon was penalised for a high tackle and Park stand off Paul Trendall hammered the straight kick between the uprights.
Halifax were forced to show their defensive mettle as Westcombe Park looked to seize the initiative and Oli Marns produced an excellent try-saving tackle before the hosts infringed and the visitors were able to clear their lines.
But nerves were calmed right on half time when Westcombe Park gave away a penalty and Knowles found his range to hammer over a kick from some distance.
An inspired substitution saw Jonathan McMillan give way to fellow front row forward George Jenkins at the start of the second period and within four minutes, a superb drive by the visiting pack propelled the Rotherham loan man over the line. Knowles was again successful with the kick.
It was just the start that Halifax needed and the players visibly grew in confidence.
They were snappy, stubborn and resiliant, attributes that have been evident this season but not always at the same time.
The tactic may have been repetitive but it was effective. Tom Eaton found touch and Halifax collected the lineout and drove for the line, Brown grabbing his second try and Knowles converting.
Then it was hooker Will Kay's turn to profit, plunging over in his last action before being replaced by Rob Townsend, Knowles seeing his conversion attempt blown wide of the posts again.
Craig Aikman decided it was time the backs showed their class but nobody was able to profit from one of his trademark bursts.
It was back to driving tactics, which enabled Matt Harrison to ground the ball, Knowles this time using the breeze well to send his conversion across the face of the posts and letting the elements suck it back in for an excellent kick.
Park had nothing to offer at this stage and a thoroughly agreeable, if very wet, afternoon was completed right on the whistle when Aikman broke again and this time no home player had either the wit or the will to chase him. He had the simplest of jobs to plant the ball down, Knowles rounding things off with his fourth conversion of the afternoon.

STAR MAN
With all due respect to the Halifax backs, this was a day when the forwards needed to step up to the plate.
And to a man they did.
Even though Tom Eaton's tactical kicking set up a number of Halifax tries and Joe Knowles's place kicking was immense in terrible conditions, they could have no complaints about the destination of this week's points.
Richard Brown set about his afternoon's work like a man who perhaps felt he had something to prove.
Not always a fixture in Rhys Morgan's starting line up, Brown threw himself into the fray with a dogged determination that not only brought him two well-worked forwards tries, but also placed him in the thick of the action as Halifax worked on dominating the opposition up front.
Gareth Lewis doesn't take much persuading to take up the mantle and his phenomenal workrate was to the fore again.
He scrabbled and scratched around, put himself in the faces of the opposition and was always handily placed to put in a telling tackle.
Matt Harrison is having a superb first season at Halifax and he continued to show why he is held in such high regard with another all action display - this time from the second row.
His physical presence was a key ingredient in the success, shoring up and driving on the Halifax forwards and also piling in for another well-worked try.
Brown earns three points in the season long competition with Lewis picking up two and Harrison one.
