Nahki Wells struck at the double as Huddersfield Town finally ended their long wait for a home win.
But a match settled by a 57th-minute penalty will be remembered just as much for new loan signing Grant Holt’s impressive cameo performance.
The Wigan Athletic striker came off the bench in the 64th minute with his side already 2-1 to the good.
And the rugged frontman, who was playing Premier League football for Aston Villa last season, certainly made his mark to help Town clinch a first win under Chris Powell and a first at home in 12 attempts.
Millwall immediately looked unsettled by Holt’s powerful presence, so much so that they had four players booked as they became more stretched after his arrival.
And if he can have that effect in half an hour (there were more than five tense minutes added on) what can he do in a whole game?
The 33-year-old will clearly need time to get up to speed, having made only one substitute’s appearance for his parent club this season.
But his arrival, sealed in the final build-up to the match and not officially confirmed until his name appeared on the teamsheet, caused a buzz around the stadium.
And his entrance in place of injured skipper Lee Peltier gave Town that vital pick-me-up at a crucial point of the contest.
Powell’s substitutions were more effective than those of opposite number Ian Holloway, who made three changes in the 74th minute.
Sean Scannell came on for the impressive Jonathan Hogg in the 85th minute, combining with Holt to help keep the ball in the Millwall half.
And Murray Wallace replaced Wells in the first of the five minutes and 56 seconds which were added on.
That meant Town ended the way they had started, with three centre-backs on the field.
From the kick-off, it was Peltier, Lynch and the influential Mark Hudson.
With Tommy Smith and Jack Robinson pushing up as wing-backs, Town made good use of the extra man in midfield, where Conor Coady and Jacob Butterfield operated alongside the busy Hogg.
They were able to stifle much of Milllwall’s passing game.
And when the ball did get as far as lone frontman Ricardo Fuller, he was well dealt with.
While former Sheffield Wednesday centre-back Mark Beevers forced a save from Alex Smithies with a hooked shot from a second-half corner, Ed Upson was Millwall’s main threat.
He curled a shot against the bar after Town were unable to fully clear a corner in the first incident of any real note (this was a real slow burner of a match).
Then he rifled in his side’s equaliser from ex-Town loanee Scott McDonald’s pass just four minutes after Wells had made the most of Harry Bunn’s touch-on with a well-struck shot which gave keeper David Forde no chance.
Bunn’s performance (the 21-year-old won the oh-so-vital penalty which Wells despatched with aplomb) was another positive for Powell, the concession of an equaliser a negative.
At least Town showed the character and determination to fight back, and after conceding several late goals this season, it was good to see them shut up shop after going ahead for the second time to ensure a second Championship win of the season.
This long-awaited success should boost confidence ahead of the crunch grips to Wolves on Wednesday and Blackburn Rovers on Saturday.
Town, whose last home triumph came on March 1, when Barnsley were beaten 5-0, are out of the bottom three.
And while there is still an awful lot of work to do, this was a great starting point.
