blundering" and that the "allied operations proceeded with clockwork precision." Naval historian Jonathan Dull has described de Grasse's 1781 naval campaign, which encompassed, in addition to Yorktown, successful contributions to the French capture of Tobago and the Spanish siege of Pensacola, as the "most perfectly executed naval campaign of the age of sail", and compared the string of French successes favorably with the British Annus Mirabilis of 1759. He also observes that a significant number of individual decisions, at times against orders or previous agreements, contributed to the success of the campaign: French ministers Montmorin and Vergennes convinced the French establishment that decisive action was needed in North America in order to end the war. The French naval minister Castries wrote orders for de Grasse that gave the latter sufficient flexibility to assist in the campaign. Spanish Louisiana Governor Bernardo de Gálvez released ships and troops to cover French territories while de Grasse sailed north with most of the French military establishment in the West Indies. Spanish Cuban colonial official Francisco Saavedra cooperated in the decision-making that enabled de Grasse's northward expedition. General Rochambeau and Chevalier Luzerne both urged de Grasse to decide on the Chesapeake. Admiral de Barras violated his orders to operate off Newfoundland, making possible the timely delivery of the French siege train to Yorktown. George Washington decided against an attack on New York and instead embarked on a risky march to Virginia. Admiral De Grasse agreed to overstay his planned time in the Chesapeake, understanding the importance of the undertaking there. Of de Grasse's negotiations with the Spanish that secured the use of his fleet and his order to the economic fleet to remain in the West Indies, Royal Navy Captain Thomas White, in his 1830 analysis of the 1781 campaign, wrote that "[i]f the British government had sanctioned, or a British admiral had adopted such a measure, [...] the one would have been turned out, and the other would have been hung: no wonder they succeeded and we failed." Legacy The principal points of commemoration of the events of this campaign are managed by the National Park Service in the Colonial National Historical Park. In addition to the battlefield at Yorktown, the park includes the Cape Henry Memorial, where the French naval victory by de Grasse is remembered.
