F. A. (Frederick Augustus) Griffiths

Serving in the Royal Artillery, he built a long army career that began with his commission as an ensign in 1813. He was later promoted lieutenant, captain, and major, and his experience in service shaped the clear, practical tone of his writing.

His best-known work is The Artillerist's Manual, first published in 1840, a handbook that was enlarged and reissued in later editions. He also wrote on infantry exercise and military law, focusing on the everyday needs of soldiers and officers rather than abstract theory.

Because his books were designed as working guides, they remained useful well beyond their first publication and still survive in major public-domain collections today. For listeners interested in military history, his work offers a direct window into how the British Army trained and organized itself in the 19th century.
