Two second half goal were enough to give the home side the points in a game in which they rarely looked troubled.
The Scholars were forced into making a number of changes due to injuries and unavailability of several players and struggled to make an impact on a game coming after three long away trips in a week.
With James Budden back at the heart of the defence alongside manager Lee o'Leary the visitors looked fairly comfortable at the back whilst not creating much in the way of threat on the Horsham goal.
The Hornets took the lead in the 70th minute as centre half Joe Shelley was left unmarked from a corner to head home a simple effort to put the home side in front.
The points were sealed right on time as the Bar defence failed to deal with a long clearance from Bentley in the Hornets goal, Greg Cundle running on to score in an empty net.
