October 19 is the 292nd day of the year (293rd in leap years) in the Gregorian calendar. There are 73 days remaining until the end of the year.
On this day in 1781, hopelessly trapped at Yorktown, Virginia, British General Lord Cornwallis surrenders 8,000 British soldiers and seamen to a larger Franco-American force, effectively bringing an end to the American Revolution.
The Siege of Yorktown or Battle of Yorktown in 1781 was a decisive victory by combined assault of American forces led by General George Washington and French forces led by the Comte de Rochambeau over a British Army commanded by Lieutenant General Lord Cornwallis. It proved to be the last major land battle of the American Revolutionary War in North America, as the surrender of Cornwallis’s army prompted the British government eventually to negotiate an end to the conflict.
In 1780, 5,500 French soldiers landed in Rhode Island to assist their American allies in operations against British-controlled New York City. Following the arrival of dispatches from France that included the possibility of support from the French West Indies fleet of the Comte de Grasse, Washington and Rochambeau decided to ask de Grasse for assistance either in besieging New York, or in military operations against a British army operating in Virginia. On the advice of Rochambeau, de Grasse informed them of his intent to sail to the Chesapeake Bay, where Cornwallis had taken command of the army. Cornwallis, at first given confusing orders by his superior officer, Henry Clinton, was eventually ordered to make a defensible deep-water port, which he began to do at Yorktown, Virginia. Cornwallis‘s movements in Virginia were shadowed by a Continental Army force led by the Marquis de Lafayette.
The French and American armies united north of New York City during the summer of 1781. When word of de Grasse‘s decision arrived, the combined armies began moving south toward Virginia, engaging in tactics of deception to lead the British to believe a siege of New York was planned. De Grasse sailed from the West Indies and arrived at the Chesapeake Bay at the end of August, bringing additional troops and providing a naval blockade of Yorktown. He was transporting 500,000 silver pesos collected from the citizens of Havana, Cuba, to fund supplies for the siege and payroll for the Continental Army. While in Santo Domingo, de Grasse met with Francisco Saavedra de Sangronis, an agent of Carlos III of Spain. De Grasse had planned to leave several of his warships in Santo Domingo. Saavedra promised the assistance of the Spanish navy to protect the French merchant fleet, enabling de Grasse to sail north with all of his warships. In the beginning of September, he defeated a British fleet led by Sir Thomas Graves that came to relieve Cornwallis at the Battle of the Chesapeake. As a result of this victory, de Grasse blocked any escape by sea for Cornwallis. By late September Washington and Rochambeau arrived, and the army and naval forces completely surrounded Cornwallis.
After initial preparations, the Americans and French built their first parallel and began the bombardment. With the British defense weakened, Washington on October 14, 1781 sent two columns to attack the last major remaining British outer defenses. A French column took redoubt #9 and an American column redoubt #10. With these defenses taken, the allies were able to finish their second parallel. With the American artillery closer and more intense than ever, the British situation began to deteriorate rapidly and Cornwallis asked for capitulation terms on the 17th. After two days of negotiation, the surrender ceremony took place on the 19th, with Cornwallis being absent since he claimed to be ill. With the capture of over 8,000 British soldiers, negotiations between the United States and Great Britain began, resulting in the Treaty of Paris in 1783.

Charles Mason and Jeremiah Dixon complete their survey of the boundary between the colonies of Pennsylvania and Maryland as well as areas that would eventually become the states of Delaware and West Virginia. The Penn and Calvert families had hired Mason and Dixon, English surveyors, to settle their dispute over the boundary between their two proprietary colonies, Pennsylvania and Maryland.
Congress, and a majority of the American public, had not been supportive of the Reagan administration’s efforts to topple the Sandinista government in Nicaragua. Reagan began a “secret war” to bring down the Nicaraguan government soon after taking office in 1981. Millions of dollars, training, and arms were funneled to the Contras (an armed force of Nicaraguan exiles intent on removing the leftist Nicaraguan regime) through the CIA. American involvement in the Contra movement soon became public, however, as did disturbing reports about the behavior of the Contra force. Charges were leveled in newspapers and in Congress that the Contras were little more than murderers and drug runners; rumors of corruption and payoffs were common. Congress steadily reduced U.S. assistance to the Contras, and in 1984 passed the second Boland Amendment prohibiting U.S. agencies from giving any aid to the group.
It was raided 9 days later by the police. She served 30 days in prison. An initial appeal was rejected but in 1918 an opinion written by Judge Frederick E. Crane of the New York Court of Appeals allowed doctors to prescribe contraception.
On this day in 1815, 

The Bavarian royalty invited the citizens of Munich to attend the festivities, held on the fields in front of the city gates. These famous public fields were named Theresienwiese-“Therese’s fields”-in honor of the crown princess; although locals have since abbreviated the name simply to the “Wies’n.” Horse races in the presence of the royal family concluded the popular event, celebrated in varying forms all across Bavaria.
The Mary Rose was a carrack-type warship of the English Tudor navy of King Henry VIII. After serving for 33 years in several wars against France, Scotland, and Brittany and after being substantially rebuilt in 1536, she saw her last action on 19 July 1545. While leading the attack on the galleys of a French invasion fleet, she sank in the Solent, the straits north of the Isle of Wight. The wreck of the Mary Rose was rediscovered in 1971 and salvaged in 1982 by the Mary Rose Trust in one of the most complex and expensive projects in the history of maritime archaeology. The surviving section of the ship and thousands of recovered artefacts are of immeasurable value as a Tudor-era time capsule.
On this day in 1776, the Continental Congress formally declares the name of the new nation to be the “United States” of America. This replaced the term “United Colonies,” which had been in general use.
