Match ends, Charlton Athletic 3, Huddersfield Town 0.
Huddersfield manager Chris Powell endured a miserable return to Charlton as Tony Watt hit a brace as the Addicks stormed to three points.
Powell played more than 200 times for the London side and was manager for three years between 2011 and 2014.
They fell behind in the first half as Icelandic winger Johan Gudmundsson struck in a free-kick from 25-yards.
Scottish striker Watt netted twice in the second half, calmly slotting in his first, before firing home the second.
The victory allowed Guy Luzon's side to leapfrog their opponents into 12th place, while the Terriers drop down to 14th.
The visitors had the ball in the net in the first half, but striker Ishmael Miller was penalised for hauling down home goalkeeper Stephen Henderson.
The deadlock was broken midway through the first half as dead-ball specialist Gudmundsson curled in a free-kick past visiting keeper Alex Smithies.
Miller had a chance to level the scores soon after, but dragged a shot wide from the edge of the area.
Huddersfield were punished for that missed chance in the second half as Igor Vetokele found Watt, who steadied himself before firing home.
The Terriers' Murray Wallace hit a low drive that was kept out by Henderson, before Watt found room to break forward and wrap up all three points.
Charlton manager Guy Luzon:
"My target when I'm coach is to bring results and the way we bring the results.
"It was very important for us that today with a full stadium that the fans and the people around the club would go home with a good feeling. It's also very important the way we play.
"When I win ugly it's okay but I like to win beautiful. I believe, if you play ugly football, in the long-term you will not bring results.
"Tony is a player that in the summer I fought a lot to sign him at Standard Liege and I'm happy that me and him are together at Charlton now."
Huddersfield manager Chris Powell:
"We were second best. We were beaten by the better team and we just couldn't get going over the course of the game. We didn't deserve anything.
"My relationship with Charlton supporters and the way they are, I wouldn't think anything less of them.
"It was beyond what any supporters would do to the opposition manager. But I am not surprised with how they were.
"It was very touching and emotional for me but I am quite embarrassed as well. They have moved on and we have moved on, but it was a great moment for me in my long career and it's something that I won't forget."
