“The Moonlight Battle” (The First Battle of Trafalgar)
British Admiral George Rodney, with 21 ships of the line, engages an inferior Spanish squadron of 11 ships that departs Cadiz. Rodney, on his way to the Americas, gleans information about the Spanish squadron from a captured merchantman and reverses his course. The Spanish, being outnumbered, try to flee back to port. Only one Spanish ship manages to return to the safety of the port of Cadiz. Although the victory has no major strategic significance, Rodney’s order of “general chase” and fighting by moonlight make this a legendary engagement.

Russia creates the League of Armed Neutrality

April 8, 1780
The British commence an attack upon Charleston, South Carolina
The British, commanded by General Henry Clinton, begin what is termed “the one solid British triumph of the war.” This bold move is intended to subjugate the South from Georgia to the Chesapeake.

April 14-15, 1780
Staten Island Expedition
A force of 3,000 men is led by General William Alexander (Lord Stirling) from Elizabethtown Point to Staten Island, in an attempt to surprise the British. The British are informed of the raid and after spending an entire day in snow and below freezing weather, the Americans withdraw after capturing 17 prisoners and a marginal amount of booty. Alexander’s losses total 6 men killed. The unruly behavior of the militia accompanying his forces causes the British to retaliate by burning the Elizabethown courthouse and the academy at Newark.

May of 1780

May 12, 1780
The worst American defeat during the Revolution
Charleston surrenders on 12 May. The British capture in excess of 3,000 Patriots and themselves lose about 250 killed and wounded. Carelessness causes a massive explosion of 180 barrels of captured powder and somewhat mars the victory. Neither Clinton nor the American commander, General Benjamin Lincoln, displays any inspiring leadership. When Clinton learns of an impending French expedition, he determines that he should be in New York, and General Charles Cornwallis assumes command of British forces in the South.

May 29, 1780
Waxhaws, South Carolina
After the surrender of Charleston on May 12, the 3rd Virginia, commanded by Colonel Abraham Buford, is virtually the only organized Patriot formation in the colony. British Colonel Banastre Tarleton is given the mission to destroy any colonial resistance. A cavalry charge breaks the Continental line, and Ensign Cruitt is cut down as he raises the white flag of surrender. This brings about the term “Tarleton’s Quarter,” which in the eyes of the Patriots is no quarter at all. The Continentals lose 113 killed and 203 captured, the great majority of these prisoners being wounded. British losses total 19 men and 31 horses killed or wounded. The defeat becomes a propaganda victory for the Continentals as they exploit the “massacre” that ensued.

Huck’s Defeat
Captain Christian Huck, a prominent Loyalist attorney from Philadelphia, leads a mixed force of British dragoons and Loyalists from Rocky Mount against the backwoods Scotch-Irish, whom he loathes. The engagement takes place at Williamson’s Plantation when the Patriots launch a surprise attack at dawn inflicting complete defeat on the British forces. British losses are variously given at 25-50 killed, including Huck, at least twice as many wounded, and 29 captured. Continental morale receives a boost.

De Kalb remains with the force as part of Gates’ headquarters staff.

Each side loses about a dozen men killed or wounded.

August 1-2, 1780
Canajoharie Settlements
Located in the Mohawk Valley, these settlements are raided by the Mohawk Indian Chief Joseph Brant. Brant and his Indians kill 16 settlers, burn a large number of homes and other buildings, while killing or driving off over 300 head of cattle. He avoids forts and other fortified positions and contents himself with the destruction of the countryside. There were no massacres of settlers, which many attribute to his being in sole command and the fact that no Loyalists accompany him.

August 15, 1780
Action at Port’s Ferry, South Carolina
General Francis Marion, the “Swamp Fox,” and his irregular cavalry force of 250, rout a party of Loyalists commanded by Major Micajah Gainey. Marion has 2 men wounded, while the losses of the Loyalists are unknown.

August 16, 1780
Battle of Camden, South Carolina
This battle is a major defeat for the Continental army. General Horatio Gates seriously overestimates the number of soldiers he has available for combat and it is too late to withdraw when he realizes his mistake. Baron Johann De Kalb receives numerous wounds and succumbs a few days later. Over 900 Americans die and another 1,000 are captured. Additionally, 22 wagonloads of equipment, along with 2,000 muskets and a large amount of ammunition, fall into British hands. The British, led by Lord Cornwallis, lose 68 killed and another 245 wounded in this lopsided victory.

August 18, 1780
Battle of Fishing Creek, South Carolina
Led by Banastre Tarleton, 350 Loyalists locate an American force commanded by General Thomas Sumter about 40 miles from Camden. Tarleton catches the Americans totally unprepared killing 150, capturing 300, and freeing 100 British prisoners. British losses are 16 killed. This battle makes Tarleton, in British eyes, a national hero.

August 18, 1780
Action at Musgrove’s Mill, South Carolina
This engagement is another action that follows Camden and precedes Kings Mountain. Patriot Colonels Elijah Clarke and Isaac Shelby command a militia force that repels an attack by Loyalists.

Henry Laurens, a member of the Continental Congress, departs Philadelphia on 13 August, for a mission to Holland on the brig Mercury. He is captured off Newfoundland by the British frigate H.M.S. Vestal. Laurens throws his confidential papers overboard but they are recovered by the British and later used as a pretext for declaring war against Holland. He serves 15 months as a prisoner in the Tower of London before being released, in large measure, because of the combined efforts of Benjamin Franklin and Edmund Burke.

September 4, 1780
Action at Blue Savannah, South Carolina
Following up on his success at great Savannah, Francis Marion, the “Swamp Fox,” and 52 of his men ride to the east to escape pursuing Loyalists. However, another force of
Loyalists, over 250 strong, come at him from the northeast. After routing the advance guard, Marion causes the main body of 200 to panic and flee by a sudden charge. This breaks the Loyalists in the area and attracts another 60 volunteers to the Patriot cause.

André is hanged at Tappan, New York, on 2 October despite his plea to be executed by a firing squad. He faces execution with courage that is greatly admired by the Continental forces.

October 7, 1780
Battle of Kings Mountain, South Carolina
Major Patrick Ferguson and his entire force of 1,100 Loyalists are either killed, captured, or wounded in this engagement with 1,400 frontiersmen led by Colonel William Campbell. Ferguson is the only individual in the battle that is not an American. The Loyalists forces rely on massed fire from volleys and the bayonet while the Americans use long rifles to pick the Loyalists off at long range, including Ferguson, who is killed by being shot off his horse while leading a charge. This is not the most glorious day for the Americans as they kill many Loyalists while they try to surrender. This battle forces Cornwallis to abandon his invasion of North Carolina.

October 15, 1780
Action at Middleburg (Middle Fort), New York
A combined force of 1,000 British regulars, Hessians, Loyalists, and Indians led by Sir John Johnson and Chief Joseph Brant attempt an unsuccessful attack upon Middleburg.

The British forces retreat in the direction of the Schoharie Valley and content themselves with destroying everything in their path.

Battle at Fort Keyser (Palatine or Stone Arabia), New York

Brown and one-third of his men die when Van Rensselaer’s force fails to attack Johnson’s rear.

A force of Continental dragoons commanded by Colonel William Washington obtains the surrender of a Loyalist force by guile. They use the “Quaker gun trick,” i.e., fabricating a cannon from a pine log. The approximately 100 Loyalists led by Colonel Rugeley surrender rather than face “bombardment.”

Engagement at Halfway Swamp, South Carolina
