Chris Powell was delighted to claim Huddersfield's scalp, ensuring Charlton took control of League One's promotion race.
The Yorkshire club arrived at The Valley looking to extend their record-breaking unbeaten league run to 44 matches. But first-half goals from Yann Kermorgant and Hogan Ephraim moved the Addicks seven points clear at the top of the table with a 2-0 victory.
"For us to be the ones who stopped their record is pleasing and everyone will remember us as the ones who did it. But there are plenty of games still to go. We have done nothing yet," said manager Powell.
"It was a good advert for League One. They settled quicker than us but as the game went on we grew in confidence. It was a big occasion. I tried to play it down with the squad but it was a big game for a lot of them and they came through well. But we've done nothing yet."
Kermorgant was stretchered off at the end but Powell insisted the striker will be soon be back in action.
He added: "He's okay, it was a twist and it's not too serious."
