Russ Wilcox could not hide his delight after guiding Scunthorpe United to promotion despite a 2-0 defeat at Exeter City.
The Iron saw their 28-match unbeaten run ended by Exeter, who guaranteed survival with the win, but Fleetwood Town's draw with Southend meant Scunthorpe cannot be caught in the race for promotion.
Craig Woodman opened the scoring with a stunning 25-yard strike and Jimmy Keohane wrapped up the win with his long-range shot squirming through the body of goalkeeper Sam Slocombe.
"We are all delighted," Wilcox said. "I don't want to touch on the game too much because that was really disappointing but the bigger picture is we have got the club back up to League One at the first attempt.
"It is an outstanding achievement from everyone at the football club - it has been a team effort. Our 28-match unbeaten run is ended but the main thing is that we are promoted.
"The main ingredient has been hard work and quality within the group. The group have been outstanding; it has been a remarkable group effort.
"Huge credit to Exeter - in the two games against us this season, we look at them and say how are they looking for Football League survival? They should have been at the same end of table as us but obviously they have not been consistent."
Exeter first-team coach Rob Edwards addressed the media post-match and while he was happy that the Grecians ensured their survival, he said they should never have been in the situation to begin with.
"It was a relief, we have been looking at the league table for a long time and we have been getting closer and closer to it," Edwards said. "It is a great relief to everyone and what a great performance at just the right time.
"The players are frustrated with where we are in the league with the group of players that we have got, the staff know we can all do better, so we will take it from there.
"We have shown flashes of what we can do, but we haven't always played with that intensity and drive. It was a fantastic performance and the players were really on top of their game and determined. We didn't look like conceding and we were together.
"We scored two fantastic goals - with a left foot like that, Craig should be shooting more often and Jimmy showed just what he can do as well. We had chances to win by more as well.
"A lot of people here care about this club, it has been a tough time for everyone and it was last chance for us. We said after Monday it wasn't good enough and the players must do better and they did."
