Britain is celebrating the 70th anniversary of Queen Elizabeth II ascending the throne (on February 6, 1952).
And the first Test won by India also started on the same day. As you can see from the scorecard, the scheduled second day (Feb 7) was made the rest day following the death of King George VI.
Note the contributions of Umrigar (130*) and Mankad (12-108). India’s first Test victory was by an innings. If you look at the English scorecard, it can be inferred that many of the team were in the Test side only because their leading players of that time did not want to tour India.
