With Cavan McDonald and Keiran Morrisey providing support for County`s early forward moves, things looked bright , as Saajid Elhassan and Michael Gaskell caused Marine real problems.
Indeed it got even brighter when Jack Hodgkinson pulled a considerable rabbit from his hat by lashing a snorter home from distance to give the blues the lead on 20 minutes.
Elhassan meanwhile continued to shine, hitting the bar with one shot that deserved better 5 minutes later.
Chris Scott had struck the foot of a post earlier, thus with Marine having to work hard to keep County out another goal did not look long off.
But when it came it was Marine`s as a mix up at the back saw the Marine 7 take advantage and equalise.
That was a shock and County seemed to carry the after effects into the second half as Marine came at them with renewed vigour, but Festus Arthur and his fellow defenders seemed to have weathered the storm when another defensive error , 70 minutes in, gifted Marine what turned out to be the winner.
County, driven on by the hugely impressive Elhassan, piled it on in the last 20 minutes , the diminutive number 10 again seeing a shot thud against the bar with the keeper beaten.
Yes….County clearly wanted it, but it was too late and Marine held out heroically to take the win.
