The last unsuccessful search term from the unsuccessful searches here at Thomo’s Hole was De Grasse. Now this is an interesting one as there are a number of nautical De Grasse’s in particular and I am not sure whether the reader of the blog was looking for the Admiral or the ship. Well, true to form, I’ll give you both.
Admiral de Grasse
François Joseph Paul, marquis de Grasse Tilly, comte de Grasse (1722 – January 14, 1788) was a French admiral. The potted history of de Grasse really starts in 1776, during the American Revolution. The French Navy was assigned to assist the Americans and de Grasse was a commander of a division. He served under Louis Guillouet, comte d’Orvilliers at the First Battle of Ushant from July 23 to 27, 1778.
In 1779, he joined the fleet in the Caribbean under the command of Count d’Estaing. De Grasse distinguished himself in the battles of Dominica and Saint Lucia in 1780 and Tobago in 1781. He was involved in the capture of Grenada and fought against Admiral Rodney in the Battle of Martinique, where the French were commanded by Guichen.
De Grasse came to the aid of Washington and Rochambeau when he brought 3000 men from Saint-Domingue, landing these reinforcements in Virginia. He then won perhaps his greatest victory when he defeated the British fleet in the Battle of the Chesapeake in September 1781.
His later fortune was somewhat less successful however, being defeated at the Battle of St. Kitts by Admiral Hood and then being defeated and taken prisoner by Admiral Rodney at the Battle of the Saintes.
De Grasse – the Ships
There have been five ships carrying the name de Grasse, two in the French Navy and three in the US Navy.
French De Grasse 1
The first French vessel carrying the name De Grasse was an anti aircraft cruiser of the Coubert class. This cruiser was designed in the late 1930s, of a similar design to the preceding La Galissonnière class cruisers although heavier and with improved anti-aircraft equipment. The other two ships of this class, Chateaurenault and Guichen were cancelled.
De Grasse was launched eventually in 1946, commissioned in 1956 and finally scrapped in 1974.

American De Grasse 1
The first De Grasse in the US Navy was the yacht shown below, in service in 1918. Details of this vessel are sketchy and there is no listing for this vessel in Conway’s. The US Naval Historical Center notes:
USS De Grasse, an 81′ 2 1/2″ long section patrol boat, was built in 1917-1918 at Neponset, Massachusetts, as the steam-turbine powered pleasure craft of the same name. Though ordered taken over for World War I Naval service in June 1917, she was not placed in commission until her construction was completed about a year later. De Grasse briefly served in mid-Atlantic coastal waters before being returned to her owner, J.L. Redmond of New York City, in early November 1918.
