Jessica-Jane Applegate won ParalympicsGB's third swimming gold medal in the pool while James Clegg claimed the first of a family double as he took bronze before his family immediately dashed off to see his sister Libby win silver in the athletics.
There was a bronze medal too for 16-year-old Hannah Russell who has now paid two visits to the podium from two races on her Paralympic debut.
The 16-year-old swam a controlled S14 200 metres freestyle which saw her move through the field to turn third with 50m to go. She then drew on every last reserve down the final length to overhaul her rivals and was pulling away as she touched in two minutes 12.63 seconds, a personal best by almost two seconds and a Paralympic and British record.
The City of Norwich swimmer said: "I am ecstatic, I really didn't think I could do something like that. At the last turn I could see how far ahead they were and I knew I had to give everything I had, it was my last race so I knew it didn't matter if I collapsed at the bottom of the pool, it's fine."
Applegate only underwent emergency surgery on her left foot a month ago which put her participation in doubt. She was, though, determined to compete at the Aquatics Centre.
She said: "I just tried as hard as I could just to get here. I wasn't even going to be here probably but I am. I was in pain. It was my last race, it didn't matter what happened after that. I just had to break through that pain barrier and make sure I could finish the race."
Victory means Applegate stands shoulder to shoulder with Ellie Simmonds and Jonathan Fox on top of the podium, and of the former she said: "She is such an inspiration, she is such a lovely person to be with."
Clegg had qualified third for the S12 100m butterfly and he came from fifth at the halfway point to snatch bronze in 1:00.00 with just 0.17secs separating third to fifth. The 18-year-old was clearly stunned, saying: "I guess it will sink in later on or some other time later on in the year. I am really happy with that swim."
There was disappointment though for Rhiannon Henry who was fourth in the S13 100m freestyle after being touched at the finish.
A blistering anchor leg by Robert Welbourn could not haul the British quartet into the medals in the 4x100 (34pts) freestyle relay. Daniel Pepper and Ben Procter were seventh and eighth respectively in the S14 200m freestyle.
