Port Vale manager Micky Adams was delighted with the way his side soaked up second-half Colchester pressure to claim a 2-0 win.
Adams' team threw away a two-goal lead against Swindon on Saturday, but his players dug in to keep a rare clean sheet as Colchester piled on the pressure.
Young centre-backs Jack Grimmer and Joe Davis impressed, while skipper Doug Loft struck a goal in each half of Tuesday night's League One clash at Vale Park to leave Adams thrilled.
The Vale boss said: "I'm happy with the performance in general and very pleased with the result. My players showed a lot of character to make sure we saw the game out.
"After Saturday, we worked on things in training and I thought that work paid off. We made mistakes individually, collectively and tactically against Swindon, but we put that right.
"We were particularly good in the first half. In the second half people might think we sat back a bit, but that is understandable after what happened at the weekend.
"I thought the second goal calmed us down and the clean sheet is testament to how well we've done. We rode our luck a bit but Colchester's keeper did as well. We always carried a threat going forward.
"We had good partnerships all over the pitch and Jack and Joe were excellent. I've played Doug Loft at left-back and in every position in midfield. He plays anywhere and scores goals."
