Britain doubled their medal haul in Paris after scooping two medals on the final day of the World Championships.
The men's 4x100m relay team took a silver medal behind the American favourites while Hayley Tullett grabbed a surprise bronze medal in the women's 1500m.
After a poor first changeover between Christian Malcolm and Darren Campbell in the sprint relay, Marlon Devonish tore into American Darvis Patton's lead.
Devonish gave anchor Dwain Chambers a healthy lead on Joshua Jackson but the American closed him down in the final metres to grab gold in 38.05 seconds. "It should have been gold but I will accept silver," said Chambers, who missed out on a medal in the individual 100m.
"My confidence is coming back and at least I have got something to take home with me because I didn't want to go home empty-handed like I did from the last World Championships and Olympics."
Campbell, who can come home with his head held high after also picking up a 100m bronze, limped off the track with cramp.
"We were so up for it and we were so eager to get the baton," said Campbell.
"But it bodes well for next year's Olympic Games."
Tullett doubled the celebrations for Britain in the next track event at the Stade de France, as she battled for bronze in the women's 1500m.
The 30-year-old went into the event knowing that she had an outside chance of a medal and she timed her run to perfection, accelerating down the home straight to clinch third place.

Tullett's time of three minutes 59.95 seconds smashed her personal best and saw her become just one of three British women to dip below the four-minute mark. "It was such a shock when I crossed the line I did not know how to react," said Tullett, who won Commonwealth silver in Manchester.
"I knew it was quite a wide-open final on paper and I wanted to achieve something and it was a case of eyes down and bloody run and keep going for the line."
It was not all good news for the British team as Steve Backley's bid for a global gold medal in the javelin fell well short of the mark in Paris.
The 34-year-old could only finish in ninth place with his best throw of 80.13m and now only has one shot left at an elusive gold on the world stage at the Olympics next year. "I felt good in my mind and was up for it from an emotional point of view, but my body did not react in the way I wanted it to," said four-time European champion Backley.
"It's incredibly frustrating and it hurts that I've put all this time and effort in only to throw less.
"But there is a fire in my belly now for next year and I'll be fired up for Athens."
The quartet of Ian Mackie, Sean Baldock, Chris Rawlinson and Daniel Caines put in a gutsy performance in the men's 4x400m relay and finished back in fifth place.
In the women's event, Lee McConnell, Jenny Meadows, Catherine Murphy and Natasha Danvers struggled against a high-class field and crossed the line in seventh place.
In the first event of the day, the women's marathon, Jo Lodge battled her way through the field to finish in 39th place.
