The first time it happened, the date was November 18, 1999.

On that day, Dartmouth ended the Harvard women's hockey team's 33-game winning-streak, spoiling its home opener on the night the 1998-1999 championship banner was raised to the rafters of the Bright Hockey Center.

A few months later, in March, it would happen for the third time, this time in the ECAC tournament. A month before, the Big Green had defeated the Crimson in Hanover, its second win over Harvard during the season.

The Crimson needed to defeat the Big Green in their ECAC semifinal match-up to advance to the tournament finals in hope of securing a bid for the AWCHA national championship tournament, but this was not to be.

Harvard fell in overtime, 3-2.

So not once, or twice, but three times in the same season the Big Green had overcome the Crimson. At this point, the rivalry was clear.

The rivalry will be renewed at 2 p.m on Saturday at Hanover when No. 5 Harvard (2-2, 2-0 ECAC) faces off against No. 1 Dartmouth (5-0, 5-0 ECAC). The Crimson will be looking to regain its status as the team to beat in the ECAC.

"We didn't do what we needed to do [last season]," Crimson senior defenseman Julie Rando said. "We left it in the hands of others and it didn't go our way."
