The match you are referring to, Wales 0 vs. England 3, took place on January 19, 1957, in the Five Nations Championship, which is now known as the Six Nations Championship. It was a closely contested rugby union international match between Wales and England, held at the Cardiff Arms Park in Cardiff, Wales.
The solitary score of 3 points for England likely came from a penalty kick or a drop goal, as tries were worth only three points at that time in rugby union. The match is remembered for its defensive intensity and for being a low-scoring affair.
While the scoreline might suggest a lack of action, matches between Wales and England have always been fiercely competitive and closely fought encounters, with both teams having a rich history of success in international rugby.
