England took five wickets for 16 runs in the final 45 minutes of play to take charge of the one-off Test against India in Bristol.
Seventeen-year-old Shafali Verma was dismissed just four runs short of a momentous century for India and her dismissal sparked the collapse which gave England a 209-run lead.
Here, the PA news agency takes a look at day two.
The future is bright
It was heartbreak for Verma, who scored 96 opening the batting for India before she mistimed a drive over the top and picked out Anya Shrubsole as Kate Cross made the debut.
On England's side, 22-year-old debutant Sophia Dunkley brought up her maiden Test half-century in the morning session and was 74 not out when Heather Knight declared with England 396 for nine. It was an impressive display from Dunkley, who was only awarded her first central contract earlier this month.
England's bowling
After striking 95 with the bat in England's first innings, Knight's decision to bring herself on to bowl in the final hour of play proved a crucial one as she went on to take two wickets for just one run in a six-over spell.
India's spinners had looked the more dangerous of their bowling options in the first innings, but England had included just one front line spinner, Sophie Ecclestone, with Mady Villiers and Sarah Glenn both included in the wider squad, but not included in the final XI.
It was a difficult task for England's seamers, but Knight and Ecclestone found decisive breakthroughs at the end to gain control.
The pitch
It had been the key focus before the match started, after Knight revealed the day before that the strip designated for the Test match would be one used by Gloucestershire in a T20 a week previously. The decision was widely criticised and the England and Wales Cricket Board issued an apology.
Although it did not play a significant role on the opening day, Thursday provided a flat track that did not offer anything to the seam bowlers, with very little movement from the red Kookaburra after the first few overs.
Over rate
India had laboured through their overs on the opening day, with eight lost from the first day's play, and it was a similar story on day two. The tourists took their time getting through their overs, but the game sped up when England took their turn in the field.
India's batting
In reply to England's total, India's openers looked composed. Verma and Smriti Mandhana shared an impressive 167-run partnership to give India a good platform.
However, after the dismissals of the opening pair, England began to dominate.
