Play came to a halt in the gloom of a London evening at The Oval with England agonizingly close to victory, needing just 21 runs from four overs.
Set 227 in 44 overs after a sporting declaration from Australian skipper Michael Clarke in the unlikely bid to force a result, England's Kevin Pietersen and Jonathan Trott set England on course in the run chase with a rapid 77-run partnership. England was 206-5 when play was stopped after a dramatic day. The 447 runs scored on Sunday are comfortably the most ever scored on the last day of a test match. Pietersen set The Oval alight with 50 from 36 balls.
A day that started a half-hour late and which was heading toward a dull draw ended in a 3-0 Ashes series victory for the hosts. England was presented with the tiny pottery urn - said to contain the Ashes of English cricket - awarded to the winners of cricket's famous rivalry. The next defence will start in November in Brisbane, Australia.
Australia scored 492-9 declared in its first innings before the game was shortened by rain that prevented any play on Saturday's fourth day at The Oval.
"Fair play to Australia for pushing the game on," said captain Alastair Cook. "It made for a really good spectacle. I'm very proud of the way the lads have done it."
England resumed on the last day at 247-5 and added quick runs through Matt Prior (47) and Ian Bell (45) before it was dismissed for 377.
Clarke decided on a risky strategy of trying to tempt Cook into accepting a run rate challenge by thrashing 111-6 in 23 overs and declaring at tea, setting England 227.
Clarke may have been hoping for some more runs but Stuart Broad snatched four wickets to slow the Australian run rate as Clark threw caution to the wind.
In the last innings, Root fell for 11 with the score at 22 but Cook and Trott batted aggressively in a partnership of 64 before Cook was trapped lbw by James Faulkner. It was Faulkner's fifth wicket of the day — he took four wickets in England's first innings.
The teams now play a series of limited-overs internationals before Australia flies home in mid-September after three and a half months in England to prepare for another five-test Ashes series.
There's also a possibility England may be without coach Andy Flower, who has been credited with recent successes. He refused to comment on a newspaper report saying he planned to step down.
"We've got to enjoy the moment and not look too far ahead. We have to enjoy this evening," he said.
It's difficult to say which team will be more optimistic in Australia. The English have been the clear victors in the big moments during this series, but the Australians have run them closer than the 3-0 series scoreline suggests.
At Old Trafford, rain played a big part in foiling an Australian victory. The first test win for England was by just 14 runs. The second match at Lord's was a thumping 347-run win.
With those two wins, and the draw at Old Trafford, the Ashes were lost to Australia. Ian Bell, voted player of the series, was the difference in a low-scoring fourth match in Durham, showing that it was the batsmen who made the difference.
While Australia's bowlers, led by Peter Siddell and a Ryan Harris who managed to stay fit, were consistently dangerous and challenging, the batsmen were a major disappointment. Clarke managed a big innings of 187, but very few others impressed.
Usman Khawaja only managed 114 in six innings before he was dropped. Ed Cowan lasted just one game. Shane Watson scored 418 in 10 innings, including a century in the last test, but the Australians could not score runs when they really needed them.
The batting lineup became stronger as the tour wore on. David Warner had an astonishing tour. He was suspended after punching rival opener Root in a bar at the start, was banished to a tour in Zimbabwe but returned quickly as Australian form collapsed on England's seaming wickets, where reverse swing is commonplace. Warner introduced solidity to the batting, as did Chris Rogers.
English bowlers like James Anderson and Stuart Broad have mastered the art of reverse swing, but will not find conditions as friendly on the hard, dry wickets in places like Melbourne, Perth and Adelaide.
Broad is likely to face hostility on and off the field in Australia, whose coach Darren Lehmann described the England player's refusal to walk after clearly edging a ball to slip as "blatant cheating" in a light-hearted radio interview. Lehmann was fined about $3,000 for the comments. The decision on Broad was just one of the glaring umpiring decisions in the series.
England & Wales Cricket Board Chairman Giles Clarke was angry that the umpires took the players off for bad light, spoiling a thrilling climax to the game.
"It's totally unsatisfactory the way the game ended - the rules are clearly unacceptable and I expect ICC chief executive David Richardson to change it at the next ICC chief executives' meeting," Clarke said.
