Ronald Welch (Ronald Oliver Felton) was born in Glamorgan and for much of his life was a teacher of history, and Headmaster of Okehampton Grammar School. He fought in the Welsh regiment during World War II. He published a number of historical novels for children, including Knight Crusader in 1954, for which he won the Carnegie Medal.
"Ronald Welch took one aspect of the past, military history, and made it his own. No other historical novelist for children is as good on battles as he is. His books are extremely well-researched, full of authentic detail, and always excitingly plotted."
