Saturday 22nd May 2004 - a date forever etched in the memory of everyone associated with Millwall Football Club.
After a run which began with a low-key and narrow Third Round victory over Walsall at The Den, The Lions charged through non-League outfit Telford United, Burnley, Tranmere Rovers - after a replay - and Sunderland to take their place in the club's first-ever FA Cup Final.
Dennis Wise and Ray Wilkins' side reached the Millennium Stadium without having met a Premier League side, but they were now to meet perhaps the greatest of all - Manchester United.
Sir Alex Ferguson's side boasted names such as Roy Keane, Ryan Giggs, Paul Scholes, Ruud van Nistelrooy and more - including a young and upcoming Cristiano Ronaldo - and were held for the majority of the first-half, until the Portguese nodded The Red Devils into the lead.
The Dutch striker then blasted United into a two-goal advantage from the penalty spot before he doubled his tally minutes later, but throughout, Millwall's army of travelling fans made themselves heard on the world stage, drowning out celebrations from the red end in Cardiff.
It was a day to be remebered forever. Young, old, male, female - everyone came together to produce one of the proudest moments in Millwall's history.
Take a look at our gallery from the Millennium Stadium above.
