Nottingham Forest secured promotion back to the Championship on a dramatic final day of the season.
Forest's win, combined with Doncaster's defeat at Cheltenham, saw the Reds take the second automatic promotion spot.
Julian Bennett's powerful strike and a cool Kris Commons finish put Forest in charge but Marcus Stewart teed up Jaime Peters to make it 2-1 at the break.
Lewis McGugan's fine free-kick restored the two-goal lead and Forest held on despite Andy Kirk's header.
However Forest were still pinning their hopes on Cheltenham taking at least a point from promotion rivals Doncaster.
And the Robins did their bit, beating Rovers 2-1 to ensure their League One survival and send the Reds up.
Forest threatened to have the game wrapped up by half-time after making a blistering start.
McGugan had already sent a rapsing 25-yard effort narrowly wide before Bennett put Forest ahead.
The left-back won possession and unleashed a fierce 20-yard shot which flew past Glovers keeper Steve Mildenhall.
And it was soon 2-0 when Commons slipped the ball through Mildenhall's legs after being put in the clear by Brett Ormerod.
But Yeovil hit back and a powerful run by Peters saw him finish from close range after a neat pass from veteran striker Stewart.
606: DEBATE
McGugan's stunning free-kick saw Forest stretch their lead to 3-1 and Wes Morgan almost added a fourth but his header was cleared off the line.
Yeovil responded once again and Marvin Williams went close before Kirk ensured a nervy last 15 minutes when he headed in following corner.
By this stage Forest fans were aware that Doncaster had levelled against Cheltenham at Whaddon Road.
But the Robins grabbed a late winner and Forest held on to seal their promotion and spark wild scenes of celebration as supporters filled the City Ground pitch on the final whistle.
