Nearly 100 Chelsea fans bedded down in sleeping bags in the east stand at Stamford Bridge to raise money for the next-door neighbours.
The Big Stamford Bridge Sleep Out – held on Saturday 25 March – will help veterans' charity the Stoll Foundation, based alongside the stadium in Fulham Road.
Players including World Cup winner Enzo Hernandez backed the event, signing a shirt for the raffle, while members of the club's development squad turned up to wish everyone well.
Ex-stars Kerry Dixon, Pat Nevin and John Bumstead sent messages of support to the outdoor sleepers, who were limited to sleeping bag, pillow and sheet of cardboard.
Organiser Mark Meehan, from the Chelsea Supporters' Trust, was among those bedding down. "It's now in its fourth year, and it goes from strength to strength," he said. "Saturday was a special evening, demonstrating what happens when Chelsea supporters come together."
On the Sunday morning, the club provided them with breakfast.
Boost for Stoll in Fulham
Stoll supports military veterans after they leave the armed forces, working to give them a roof over their head rather than sleeping rough.
The first sleep out was staged in 2019. Last year, Chelsea fans raised more than £22,000 for the charity. They are still adding up the total for this year, and you can contribute here.
Jill Taylor from Stoll said: "The money raised makes a real difference to the support we are able to offer our veterans."
