Gibson wasn't happy with the Cougars' effort in the first half.
"In the first half we didn't come out hustling," Gibson said. "They won 50-50 balls and on a percentage they probably won 80-90 percent of them. Give them credit. They played hard and in the first half they jumped out on us 2-0.
"Sometimes we get down a goal or two and it's hard on us. We're limited on bodies and it's always hard to play a team that has more players that play this game year round."
George Washington outshot the Cougars 19-5 on the evening and built a 3-0 lead with 18:54 to play when senior Andrea Breeden netted a goal with an assist from freshman Hannah Ellis.
Capital finally got on the board with 17:43 left when senior Lauren Johnson slipped a shot past Patriots keeper Olivia Miller.
Miller finished with a pair of saves, while Newhouse stopped six shots.
The win improved GW's record to 3-1-1 in matches in which they've surrendered just one goal. Miller also has four shutouts this season.
"We played well defensively," Ragle said. "It just seems like we outshoot everyone and then we give up one chance and it ends up a goal. Whenever we screw up, we really screw up, but for the most part we played really sound defense.
With a pair of new starters on defense in senior Maddi Wymer and junior Rachel Mears, Ragle has been pleasantly surprised by his team's defensive play through 10 matches.
"I've been very surprised," Ragle said. "They work well as a unit and they communicate. They have some breakdowns every now and then ... they're human, but for the most part we've been pretty good back there and I've been proud of them.
"We're playing pretty good right now. We're 8-1-1, of course I'd like to be 10-0, but you can't have everything you want. As long as we keep improving we'll go right into sectionals and regionals and hopefully be down in Beckley again at the end of year."
