Peter Siddle led Australia into combat on an epic first day of the Ashes but by the end of it the batsmen were in a familiar position - on the ropes.
For the second time in as many Ashes series, Siddle inspired his team on the opening day, adding a five-wicket haul at Trent Bridge to his hat-trick in Brisbane three summers ago.

England was bundled out for 215 in just 59 overs by a young attack bursting with nervous energy. That scoreline was arguably as big a surprise as the debut of teen spinner Ashton Agar; this strong English team had not been bowled out so cheaply at home since 2009, when it was rolled for 102 by Australia at Headingley.
Not so surprising given recent form was Australia's batting response. The tourists slumped to 3-22 when England's conjurer of a fast bowler, James Anderson, in his element under gloomy skies at Nottingham, bowled Michael Clarke for a six-ball duck with a ball every bit as good as the one Dale Steyn defeated the Australian captain with in Perth last summer.
The Australians were 4-75 at stumps, with Steve Smith unbeaten on 38 after using his feet to get after Graeme Swann, and Phillip Hughes seven not out.

Steven Finn, whose place in the team, like Siddle's, was in doubt before the series, removed Shane Watson and Ed Cowan in consecutive balls. Watson drove hard at a delivery that was shaping away from him and Cowan chased one outside his off stump. Both were caught in the slips.
Not for the first time in Australia's age of batting dangerously, Clarke needed to save his team.
He took a swish at the hat trick ball but survived, just. Then Anderson produced a ball that curled in, pitched and nipped away past Clarke's bat into the stumps. On the balcony of the England dressing room bowling coach David Saker stood and applauded. The ball was that good.

"We've seen him do that a few times, with absolutely magic balls and it's testament to the amount of work that he puts in and how he keeps developing his skills that he can do things like that. It's great when something like that comes off in a game and to get the Australian captain with a ball like that was exceptional for us," said Finn, who felt England had its nose in front after 14 wickets fell in the day.
"It's a tight battle at the moment. To be bowled out for 215 after winning the toss was something we hadn't hoped would happen but we are in that position now and to have them four down is a good result.
"The overcast conditions helped a little bit. We'd have liked to get a few more runs on the board but the nature of Ashes cricket, it's going to be eventful."

Just when the innings was starting to settle, Anderson came around the wicket to Rogers and rapped him on the pad. The batsman, playing his first Test innings in five and a half years, appealed the lbw decision thinking it was missing leg, but the umpire's verdict was upheld.
Earlier, Siddle took charge of an Australian attack bursting with nervous energy to take 5-50, his eighth five-wicket haul and his second in England.
Amid all the excitement about a teenager playing his first Test on the biggest stage of all, the decision to stick with the side's most experienced bowler when he was struggling paid huge dividends.
Siddle's effort to drag himself back into the contest after a first spell that leaked 27 in four overs was monumental, and Clarke deserved credit for trusting him to come good.
Siddle switched ends before lunch and produced a yorker that faded away from Root at the last moment and bowled him.
Kevin Pietersen and Ian Bell were caught in the slips but Siddle's most crucial wicket was that of Trott.
Siddle charged in from wide of the crease and drew the stubborn No.3 into a drive, which he dragged onto the stumps on 48. Trott was furious with himself and jabbed his bat at his stumps in anger.
Matt Prior lasted seven balls, and smashed a catch to Hughes at point.
Australia needed Siddle to stand up as the young attack made a nervous start.
James Pattinson opened the series with a Steve Harmison-style loosener - a ballooning bouncer that was called a wide - but then claimed the wicket the Australians wanted most, that of the unflappable Alastair Cook.
Pattinson had made no secret of the tourists' intention to attack the England captain, who pounded 766 runs in the last Ashes. He settled his nerves by enticing Cook into a loose drive and an edge, which was caught behind by Brad Haddin.
The ball was swinging and Haddin had to be athletic to catch some of the wider offerings from Pattinson.
The young spearhead later lined up the tail, hitting Stuart Broad on the shoulder and getting his wicket with another bouncer.
Mitchell Starc didn't find his groove until a swinging yorker bowled Jonny Bairstow for 37, and the left-armer had Finn caught behind next ball.
Agar, the first teenager to debut for Australia in an Ashes Test since Doug Walters in 1965, was introduced in the 16th over and saw Trott drive his first ball through the covers for four. Tall and lithe, the left-arm spinner conceded 24 in seven unremarkable overs.
Coach Darren Lehmann said the Australian underdogs had shown they were up for a fight.
"Any fan who left the ground today would have left the ground happy with both sides," he said. "It's very pleasing to bowl them out for 215 and we probably should have bowled them out cheaper if we got the areas right. We're here to play, there's no doubt about that, so hopefully the odds will come down."
