This illustrated book, first published in 1936, is an edited compilation of source material drawn from some 145 diverse naval documents covering a period of more than three centuries from 1497 to 1805. The editors’ intention was to smooth the approach to a highly technical subject, and to use original documents to give concrete illustrations of the limiting conditions of sea warfare, thus removing some common misconceptions such as that the big Spanish ships of the Armada were defeated by cockleshells manned by volunteers. Subjects include the seaworthiness of ships in Elizabethan times; Drake’s views on strategy; sea punishments; Kempenfelt’s 1782 design for a signal book; victuals; the battle of Kentish Knock (1562); the 1803 defences against invasion; Nelson’s watch off Toulon; the coppering of ships; and many other topics giving insights into the history and development of the British navy.
