HAMPSHIRE, ENGLAND—Historic England will use modern sonar, remote sensing, drone technology, and dendrochronology to investigate a site in the River Hamble, where one of four ships commissioned by Henry V during the Hundred Years War is thought to rest in the mud. Historian Ian Friel spotted the vessel some 30 years ago in an area that was once a medieval breaker’s yard in an aerial photograph. Called the Holigost, or Holy Ghost, the ship had a crew of 200 sailors and could carry hundreds of additional soldiers to war, along with seven cannon, bows and arrows, poleaxes, and spears. “The Holigost fought in two of the most significant naval battles of the Hundred Years War, battles that opened the way for the English conquest of northern France,” Friel told The Telegraph. The site is near the place where Henry’s flagship, The Grace Dieu, was discovered in the 1930s. For more, go to "History's 10 Greatest Wrecks."
