A late goal from Claudia Walker was enough to see Blues win their first Continental Cup group game.
Ward made eight changes to the matchday squad, including seven to the starting XI and was pleased with the players that stepped in.
She said: “All of the players that stepped in did well, I am really happy that they managed to get minutes under their belts ahead of our league games.
“Blackburn is a tough place to go, we knew it would be, we found a way to win the game and that’s the most important thing.
“We had a lion share of the possession and dominated large periods of the game. Overall, I couldn’t fault anyone.”
New signing Daniela Kosinska made her debut and kept a clean sheet and Ward was impressed with how she played.
She said: “It was a big ask of her to come into an environment that she wasn’t used to.
“Credit to her because she settled quickly with the girls and obviously a clean sheet is always what goalkeepers want.”
Claudia Walker was on the scoresheet again and Ward believes the goals are coming because of the hard work that she puts in.
She said: “We have done a lot of work with Claudia recently around using her body because she is a strong player, so we are happy that the goal came from her being aggressive.
“She’s getting better and better and is a real breath of fresh air at the moment.”
Ahead of Sunday’s clash with Reading, Ward knows that it will pose a different threat to what Blackburn did.
“They are a good side that sometimes go under the radar because of the bigger clubs,” said Ward. “We know it will be tough, but every game will be tough, but we just have to apply ourselves in the right way.
Carla Ward's side are back in league action with a visit to Reading on Sunday 11 October (2pm kick-off).
