“ Here's a treatise that doesn't get as much recognition that it should with aficionados of the cutlass and naval fencing. Juan Nicolas Perinat wrote it in 1758 for the Naval school of Cadiz. It introduces the french school for both officers armed with smallswords and sailors armed with cutlasses and represents probably the first complete rendition of both a cutlass treatise and the French method of espadon, as well as the first mention of contrepointe. You can find here a great translation by Tim Riviera. https://www.spanishsword.org/translations Link to the original, containing the plates: http://bdh-rd.bne.es/viewer.vm?pid=d-1628268 “
