Michael Jamieson continued Britain's fine tradition in the breaststroke when he claimed a silver over 200 metres which saw the Scot produce the fourth fastest swim in this event in history.
Jemma Lowe was sixth in the 200m butterfly final and the women's 4x200m freestyle relay were a creditable sixth but it was Jamieson who enjoyed the spotlight. The 23-year-old enjoyed a shoot-out down the final length with Daniel Gyurta which drove the Hungarian to set a new world record of two minutes 07.28 seconds, Jamieson just 0.15secs adrift.
He said: "I knew I had a bit left after last night, I ran out of pool space a bit at the end there but I'm absolutely delighted with the silver. This result tonight is what I have prepared for for I don't know how many years."
Jamieson added: "It's only in really the last 18 months it's become a target and not just a pipe dream. I think that's probably why I was quite calm before the race, there weren't too many nerves just excitement. I think that is because I had gone over it so many times in my head, I'd prepared for it in every way I could really."
Bath team-mate Andrew Willis was eighth in 2:09.44 despite having qualified third in an English record of 2:08.47. "I would have liked to have gone quicker but it was just a great experience to have been in the race," Willis said. "Michael deserves it, I'm really happy for him. He's capable of great things and we've seen that today."
Lowe's 200m butterfly final came immediately after Jamieson's medal ceremony. The crowd were still on a high as the Swansea ITC swimmer walked out to the blocks and gave her a raucous welcome. The 22-year-old had just squeezed into the final in eighth but she gave it a real go, turning third at halfway and battling down the final length to touch in 2:06.80.
She said: "I am still a little bit disappointed that I didn't get my dream but I'm also happy that I made a final at my second Olympic Games. I've definitely got hopes for Brazil (2016 Olympics), I still feel quite young, so I've still got a lot to give, and see what the future brings."
The women's 4x200m freestyle relay came away with a respectable fifth place in 7:52.37, with the United States winning in an Olympic record time of 7:42.92. The quartet comprised Caitlin McClatchey, Rebecca Turner and Jo Jackson, with Eleanor Faulkner replaced by Hannah Miley.
Fran Halsall was similarly inspired by Jamieson as she qualified for Thursday night's 100m freestyle final. She said: "It's been fantastic and it really gives you a buzz, and having MJ in before me I was like, 'MJ can do it, I've got to keep it going for the team'."
Amy Smith, though, was 14th in 54.28 so missed out on the final. James Goddard qualified for the final of the 200m individual medley. The Stockport ITC swimmer was joint seventh fastest in 1:58.49, although team-mate Joe Roebuck missed out in 11th.
