Welsh swimmer David Roberts continued Team GB's pool heroics as he took the S7 400m freestyle for his third Paralympic gold in Athens.
The 24-year-old from Swansea clocked four minutes 56.11 seconds for victory.
Roberts, who also triumphed in the 4x100m freestyle relay and the 100m freestyle, was winning Team GB's 11th swimming gold of the Games.
There were silvers for Sarah Bailey and Maggie McEleny, while James Crisp and Claire Cashmore claimed bronze medals.
Roberts, who has cerebral palsy, was five seconds clear of silver medallist Rong Tian of China and his win marks a stunning comeback from life-threatening surgery.
The Welshman was keen to savour success after finishing second four years ago.
"I was determined that wasn't going to happen tonight," said Roberts, who left team-mate Andrew Lindsay trailing in fifth.
"I'm really pleased - we had a race plan to go out and take it hard.
"I felt I could control the race, which was nice. It's a lovely feeling to be able to do that."
Bailey was winning her 16th Paralympic medal when she finished second in the SM10 200m individual medley.
Maggie McEleny also won silver, in the SB3 50m breaststroke.
Claire Cashmore was pleased with her bronze in the SM9 200m individual medley, won by South African Natalie du Toit.
Du Toit took her third gold in Athens with a new world record of 2:32.19, having already shaved 11.5 seconds off the previous record in her heat
But 2000 champion James Crisp was disappointed with his third in the men's event.
"I'm gutted. It's just not good enough," said the student from Nottingham.
Giles Long (SM8, sixth) and Anthony Stephens (SM5, fifth) missed out on 200m individual medley medals.
