This book has been produced to coincide with the 150th anniversary of Gloucester Rugby and includes details of all of the 5156 matches (3106 won, 1706 lost and 344 drawn) played by the Club from the very first on 4 October 1873 up to the end of the 2022-23 season. It also includes a summary of every season and team photographs for most seasons. The contributors to this book are all trustees of Gloucester Rugby Heritage, a charity run by volunteers and supported by Gloucester Rugby, the Gloucester Rugby Foundation and Gloucestershire Archives. This book is the last in a series of five, previous volumes having recorded the history of the Kingsholm ground, representative matches played there, Gloucester Rugby in cup competitions, and Gloucester Rugby players.
