The conditions were atrocious but it has to be said that Cambridge, in the second half, used the elements better than Halifax had in the first and that went some way to securing their victory.
Halifax went in at the break holding a narrow 11-5 lead - an advantage they deserved after a spirited and dogged display.
But they failed to get their hands on the ball in the second period as Cambridge kept things tight and pinned the home side back in their own half with a series of strong drives from their heavier pack and some tactical kicking designed to keep Halifax scurrying backwards to cover.
In fact Halifax's only real chance of the half came almost on the whistle when replacement winger Dave Hall set off on a thrilling run from almost under his own posts.
He found himself deep in enemy territory before making the fatal mistake of stepping inside instead of backing his pace, and he was brought to ground.
It was a pity because that score would have been enough to give Halifax a losing bonus point and take them into double figures for the season.
Every psychological barrier has to be broken down no matter how small and insignificant.
The players certainly started like they had something to prove following the heavy defeat at Manchester the previous week.
Despite the heavy conditions, which continued getting heavier until it reached the stage where there was standing water on the pitch, Halifax worked well as a cohesive unit, Danny McGee unfortunately knocking on when it looked as though he had breached the visitors' defences.
And when Cambridge did threaten there was some strong and well-organised defence ready to keep them out.
It took a charge down from an Iain Gordon kick for Cambridge to put their noses in front.
The visitors pounced and kept the ball alive through a number of phases that took them ever closer to the Halifax line.
When they were awarded a scrum just five yards out, powerful No 8 Thomas Powell emerged from the back and piled over, full back Luke Fielden seeing his conversion attempt blown off course.
Both sides were unable to play any kind of expansive rugby on a sticky pitch and with a greasy ball, yet both showed commendable endeavour.
And Joe Knowles backed that up with supreme confidence, opting for a shot at goal from a considerable distance after Cambridge had been penalised, his skill matching his ambition as the ball just fell the right side of the crossbar.
That gave everybody a lift with Ben Mitchell twice belying his small frame to produce crunching tackles that dumped the larger Cambridge victims firmly on their backsides.
Gordon then produced an excellent touchfinder that pushed play close to the Cambridge line and a period of intense pressure led to the visitors infringing and Knowles followed up his earlier penalty with another tremendous angled effort to edge Halifax ahead at 6-5.
Within minutes Knowles was in the thick of the action again, charging down an attempted clearance, re-gathering and outsprinting the cover for a fine unconverted try in the corner.
Halifax were well on top and putting Cambridge under pressure, forcing the visitors into errors that they just couldn't take advantage of.
However, an 11-5 interval lead was something to build on - only somehow Halifax contrived to lose the momentum.
Sadly the second half was a no-show as far as Halifax as an attacking force were concerned as they struggled to break a Cambridge stranglehold that they adopted almost from the whistle.
Fears were already mounting that a sterling home rearguard would crack when after 52 minutes, a huge drive saw Halifax feet struggle for purchase on the wet ground and flanker Glen Remnant rumbled over to leave Cambridge just one point behind at 11-10.
Not surprisingly the play was bitty and disjointed, but it was still Cambridge who looked the more likely to add to their score and they did just that when, following one of two minor flashpoints, the visitors were awarded a penalty in front of the sticks and Fielden made no mistake for a 13-11 lead.
Cambridge were then held up under the posts as Halifax failed to build any momentum and the final nail was hammered in when winger Paul Kendall stormed in at the corner, Fielden landing an excellent touchline kick.
By then the game was up, but it would have been nice for the home faithful to cheer a final try only for Hall's exciting dash to come up short.

STARMAN
With the re-introduction of Richard White into the second row, Richard Brown moved back to No 8 where he is more effective.
And he made sure coach Rhys Morgan will have a difficult decision to make about who plays there against Blackheath with Matt Harrison due back after his trip home to New Zealand.
Brown went looking for the ball at every possible opportunity and tried to drive it forward when he had possession of it. He threw himself into tackles and generally made a nuisance of himself while working his socks off for the Halifax cause.
Joe Knowles has been Halifax's top points scorer this season and he showed just why on Saturday.
Despite horrendous conditions for a goalkicker - driving wind and rain - he set his stall out with a long range penalty after Cambridge had gone ahead, added another supreme kick from the touchline then showed great awareness to charge down a clearing kick and run in for a fine try.
The hours of preparation and practice are definitely paying off.
Ben Mitchell likes to attack and there is no finer sight than to see the former Crossley Heath skipper tearing past opponents with effortless style.
But in the first half against Cambridge he produced two of the biggest hits that were worth the admission price alone.
Brown claims the three points on offer in the season long competition with Knowles two and Mitchell one.
