The queen's granddaughter Zara Phillips added to the family silver on Tuesday, helping team Britain to a second-place finish behind Germany in Olympic equestrian eventing. Princes William and Harry and William's wife Kate were in the stands to cheer on their cousin as she competed in the show jumping final portion of the three-discipline event. Phillips' mother, Princess Anne, watched as well - and then presented her daughter and the rest of the winners with their medals at the ceremony before horses and riders took a thunderous group victory lap around the Greenwich Park stadium. After racing through the treacherous cross-country course without any penalties the day before, Phillips knocked down a rail on the second jump Tuesday. Teammate Nicola Wilson knocked down one as well, dashing Britain's chances for gold.
