Polly Dugmore put on wetsuit late at night after a herd of 10-week-old animals escaped their field on to a beach
A herd of calves were saved from drowning when a vet engaged in a midnight marathon swimming race against the tide to guide them to safety.
The 10-week-old animals broke out of Bodrugan Barton farm in Cornwall and became stranded on rocks at Colona beach in the early hours of last Thursday morning with the tide rising.
