Naval Crossfire: a Comparative Analysis of Iron Projectiles from mid-18th to Early 19th Centuries European Warships

摘要

The ordnance of early Modern main maritime powers (i.e. Great Britain, France, and Spain) played an important role in conflicts for supremacy of the seas. Therefore, it was subjected to various innovation processes, in order to improve their efficiency. This study presents the characterization results of an array of iron projectiles recovered from the following sites: 1) the sloop-of-war HMS Swift (1763-1770), 2) the Spanish ship Triunfante (1756-1795), 3) the French ship Bucentaure (1804-1805), and 4) the site Deltebre I (1813). Based on data obtained using Optical Microscopy (OM), Scanning Electron Microscopy (SEM), and Energy Dispersive X-ray Spectrometry (EDXRS), a comparative analysis was performed, in order to clarify the technological differences and similarities that were present in the projectiles used by the mentioned ships.
