A highly motivated and near full strength Calne side smashed their way through a Marlborough side riding high on the back of a recent good run.
Calne scooped eight tries, seven conversions and a penalty in their 57 point haul.
Calne skipper Andrew Donegan bagged 32 points including a first half hat-trick despite sustaining an inadvertent knock in the opening play, following post match hospital treatment Donegan is suspected of fracturing two ribs.
Donegan's first-half haul of 22 points was set up by the most impressive forward performance of the season.
In stark contrast to last week's battering by Swindon College, Calne's pack was able to shove Marlborough back in the scrums.
Donegan's first try came from a rare push over scrum, the scrum half beat No.8 Damon Murphy to the ball once the forwards had claimed their scalp.
His second was similarly opportunist.
Marlborough miss-controlled a defensive five-metre scrum, allowing Donegan to pounce on the loose ball.
The third was again from the base of the scrum. He picked up and set off toward the posts, cutting through three defenders on his way.
As expected Marlborough had no intention of rolling over.
And they were rewarded on the stroke of half time with an unconverted score from a cleverly worked cross-field kick.
The second half saw the arrival of the irrepressible Ian Smart.
Making his return from retirement, Smart waved his motivational magic wand and had the boys fired up and full of belief prior to kick-off.
Guthrie Holiday collected the first try of the second half.
His pace and arching line left defenders bemused.
Neil Watkins was next, having earlier swapped positions with Murphy the new No. 8 picked up, from the base, and bullied his way over for the score.
Paul Jenkins set up former Chippenham teammate Watkins for his second try. The outside half drew the back row before laying off the inside ball for Watkins to run in.
Having missed out on two scoring opportunities, Murphy was not to be out done.
He added his name to the score sheet by finishing off another fine phase of forward play. Centre, Holiday collected his second to round off another fine performance from the 18-year-old.
