All eyes were on the host nation to follow up Wednesday's gold in the women's pairs, and Denmark, champions at the Beijing Games four years ago.

But the South Africa four - James Thompson, Matthew Brittain, John Smith and Sizwe Ndlovu - gate-crashed their party in gripping fashion.

Seemingly out of contention in the first 1500m they exploded in the closing quarter to overhaul the Danes and then Britain to rewrite their country's and the Games' rowing history.

Denmark took control from the start, with Britain, featuring Northern Ireland brothers Richard and Peter Chambers, looking dangerous in lane three.

The British four started to press Denmark, for whom Eskildi Ebbesen was seeking a fourth Olympic title.

But the big guns had no answer to South African's finishing surge, the winning crew falling over themselves in jubilation after crossing the line in front of a capacity crowd at Eton Dorney.

World champions Australia came in fourth.

"That was brutal, we were fighting, fighting, fighting," said Richard Chambers.

Teammate Rob Williams added: "It's a tough event, we wanted to win gold, so silver's not fantastic, but it is a medal at our home Olympics..."

In other finals action the all-conquering United States team, unbeaten in the past four years, added women's eight gold to their Beijing and world championship titles.

The USA comfortably held off Canada in silver with the Netherlands filling the bronze position.

New Zealand world champions Nathan Cohen and Joseph Sullivan won gold in the men's double sculls.

The Kiwi pair overhauled Italy's Alessio Sartori and Romano Battisti late on, with long time leaders Luka Spik and Iztok Cop of Slovenia taking bronze.
