For all who were lucky enough to witness it, it was a bowling spell which will never be forgotten.

But Stuart Broad has admitted the significance of his astonishing exploits on the first morning of the 2015 Trent Bridge Ashes Test didn’t hit him until the end of that historic day.

The Nottinghamshire seamer took 8-15 on his home ground to help dismiss Australia for 60, before Joe Root and Jonny Bairstow made light of the Australian attack in the afternoon.

And it was only as an enthralled capacity crowd began to filter out of Trent Bridge that Broad was able to reflect on the events of the day.

"It was a bit of a daze up until Joe Root walked off at the end of the day when it was game done,” he told Sky Sports.

"It was an amazing feeling, especially being at Trent Bridge, somewhere where I have got such great connections.

"I never expected to be having a cup of tea watching Alastair Cook walk out to bat pre-lunch having bowled."

Amidst cloudy skies, captain Cook won the toss and opted to bowl.

With his regular new-ball partner James Anderson absent through injury, Broad became his attack’s spearhead – and struck with just his third delivery of the day.

“It was the first time I'd ever bowled the first ball of the Test match, the first time I ever had to set the tone,” he recalled.

“I don't remember the 300th wicket [Broad had taken 299 Test scalps heading into the game] being on my mind, it was more about setting the tone without Jimmy.

“Looking back you see how attacking we were with the fields. For Cooky to be brave enough to put catchers there made this possible - any mistake from the batsman was just out."

"I never expected to be having a cup of tea watching Alastair Cook walk out to bat pre-lunch having bowled."

Broad’s most recent Ashes exploits have been dominated by his one-sided battle with David Warner.

The 33-year-old dismissed the Australian opener seven times last summer, but in 2015 it was Mark Wood who sent Warner back to the Pavilion.

It was a wicket which Broad rated as the most crucial of the day.

"I always find with him that if there is movement in the pitch and you are searching for an area, he goes after the fuller ball and is so dangerous. He hits width when it is swinging very well,” he said.

“To get him for nought was huge - you could see the celebrations from everyone. I think that was the biggest wicket of the day."

Broad’s stronghold over Warner forms part of an impressive record against left-handers.

Shaun Marsh was another such batsman to fall on the morning of 6 August 2015, and it sowed the seeds for what would become a fruitful tactic.

"I felt that if I had a short leg, if I could get him expecting the short ball, then that brought the fuller ball into the equation,” he recalled.

"Marsh came hard at the ball, liked to feel bat on ball, so we thought that he would push quite hard.

“The ball did the perfect amount. As bowlers, we never want the ball to nip a long way, we want it to nip half a bat's width, that's when it's so dangerous.

“I hadn't bowled that much around the wicket before this series, but the wickets of Marsh and Rogers gave me lot of confidence.

“It was exactly what I was looking to do - hold the seam up straight, target off stump and bring batsmen forward."
