Allen & Unwin, 1st ed., 1961. 243 pp., 1 plate (fldg.) + 12 tables (some fldg.). D.j., 24 x 16cm. FINE. Professor Michael Lewis was a leading authority on the Spanish Armada of 1588, and this masterly study of the guns used by both sides in the battle has long been accepted as a major contribution to the Amada affair. The essay originally appeared in eight separate issues of The Mariner’s Mirror during the Second World War (1942-43), before being published in this more convenient format in 1961. The author makes comparison between Spanish and English cannon, together with their powder and round-shot. He describes Elizabeth’s ships and their guns between 1569 and 1599, and of both fleets in 1588. Appendices look at the musket in 1588, and the missing guns of the N. S. DEL ROSARIO and the SAN SALVADOR. FINE copy.
