Dressage rider Lee Pearson joined the elite band of Paralympians with 10 gold medals as Great Britain won the London 2012 dressage team test with a world record score on Sunday.
When the results were combined after four days of team and individual championship tests at Greenwich Park, Britain, with a score of 468.817, took their fifth consecutive team gold.
They have been unbeaten in the Paralympic team competition since equestrian events were introduced in Atlanta 1996 -- and they have also never lost in a world or European championship.
Germany, with 440.970 points, took silver, and Ireland, appearing in their first Paralympic equestrian competition, won bronze with 428.313.
Sophie Christiansen, riding Janeiro 6, won her Grade Ia individual test, helping the team -- comprising her, Pearson, Sophie Wells and Deb Criddle -- to take the team gold by a landslide margin.
Pearson, already the most successful paralympic equestrian, completed his individual and team performances on Saturday.
The flamboyant 38-year-old, who won a clean sweep of three medals at each of the last three Games, was surprisingly edged into the silver position by Australia's Joann Formosa in the Grade Ib individual championship test dressage.
He has the chance to take his gold medal tally to 11 in the freestyle event on Monday.
That would make him joint second with wheelchair racer Tanni Grey-Thompson and swimmer David Roberts in the list of British Paralympic gold medal winners.
Swimmer Mike Kenny is Britain's most successful Paralympic athlete ever, winning 16 golds between 1976 and 1988.
Pearson said: "We are all really, really proud.
"I know the scores suggest there was a big gap between gold and silver, but this has been the best team effort I have known on any team. We fought very, very hard.
"I think this is the strongest team we've have ever had, but I also think it has been the toughest gold to get."
