Senior attackman Lawson DeVries began the Crimson barrage with a goal off an assist from fellow senior attackman Geoff Watson 3:45 into the second frame.
Then, 10 minutes later, junior midfielder Roger Buttles gave the Crimson the lead by tickling twine with a blistering shot past Dartmouth goalie Patrick McClammer to make it 2-1.
After that point, Harvard never trailed again.
To close out the second quarter, Wich accepted a pass from Watson with 30 seconds left and blasted a rocket past McClammer to push the score to 3-1 in Harvard's favor.
The offensive momentum for Harvard stalled in the third quarter, however, as Dartmouth came out firing. The Big Green capitalized on crucial Crimson miscues and tied the game at 3-3 on goals from attackers Scott Roslyn and Ryan Beible.
Harvard, facing the possibility of another close loss, rallied to stretch the lead to 5-3 on goals from Primm and junior attackman Dana Sprong.
"One positive of this season has been our will to win regardless of our standing," Primm said. "After the close losses to Notre Dame and UMass, we could have easily thrown in the towel, but instead [we] maintained our focus with Dartmouth."
