Danny Woodards, Eliot Richards and John-Joe O'Toole were on target for the Pirates as they cruised past a below-par Fleetwood.
Ward said: "We knew it was possible to win the game, we told the boys they could do that and they have.
"You never come to a place like this, against a team in the top six or seven and expect a comfortable afternoon. And it wasn't a comfortable afternoon, it was just good finishing and a lot of hard work. We had a lot of defending to do as well.
"The front players will get the credit but with 35 or 40 minutes to go the back four had to win the game for us and shut them out and they did.
"It was a result for front-foot football. If we had stayed off and let them play they are a good side. But we got amongst them and caused them trouble."
