Button Gwinnett was born in England in 1732. There he became a merchant. He emigrated to Charleston, South Carolina in the year 1770. Within a couple of years, Gwinnett moved to Georgia, where he was swept up among the patriots, and was elected a delegate to the Continental Congress meeting in Philadelphia. There, in 1776, he voted for independence from Great Britain, affixing his name to the Declaration of Independence. Gwinnett left Congress in 1777 in order to join the Georgia Convention to write a constitution for that state. He was shortly thereafter voted as President of the Council, which was the highest office in the state. Not simply content with this position, Gwinett attempted to acquire the position of Brigadier General. 
Lachlan McIntosh was born in 1727 in Scotland, and arrived in the American colonies at the age of eight years. He was active on the patriot side in the years leading up to the Revolutionary War, and he obtained the rank of colonel in time to assist in repelling the British from Savannah in 1776.  His skills and popularity allowed him to defeat Gwinnett and become a brigadier general in the Continental Army.
Soon after this defeat, Gwinnett, in an attempt to usurp power from McIntosh, proposed that the Georgia militia attack a British post in eastern Florida. The expedition resulted in defeat for the Georgians, possibly due to a lack of assistance from McIntosh. After an inquiry into the failed attempt exonerated Gwinnett of any misconduct, McIntosh denounced Gwinnett in harsh terms. McIntosh said of Gwinnett, among other things, that he was "a Scoundrell & lying Rascal."  Gwinnett demanded an apology, which was promptly denied to him. Gwinnett, a signer of the Declaration of Independence, challenged McIntosh, a Brigadier General, to a duel.
The two combatants met outside of Savannah, Georgia on land belonging to former royal governor James Wright on the morning of 16 May 1777. The men examined their pistols and took their stand. Gwinnett and McIntosh exchanged fire at close range. Both men were wounded in the thigh. McIntosh asked Gwinnett if he had received his satisfaction, and the men shook hands, ending the duel.  Gwinnett's wound, however, proved to be fatal. He died three days later, 19 May 1777. Gwinnett was buried in Colonial Park Cemetery in Savannah, Georgia.
McIntosh survived the duel, as well as the ensuing trial. He was, however, removed from Georgia at the request of George Walton, another Georgia politician and signer of the Declaration of Independence. Walton wrote to George Washington in August 1777 that he was "afraid the friends of the deceased, made sore by the loss of their principal, would again blow up the embers of party & dissention, and disturb the harmony & vigour of the Civil & military authorities."  In consequence, McIntosh spent the winter of 1778 at the Valley Forge camp before leading a successful expedition against the Indians in the Ohio River Valley. McIntosh returned to Georgia in 1779. He participated in the failed defense of Savannah in that year, and was captured in Charleston, South Carolina in 1780. He was relieved of his duty by the Continental Congress, though not dishonorably, and served in that body in 1784.  McIntosh died in Savannah in 1806 and is also buried in Colonial Park Cemetery.
As a final note, Gwinnett's signature is a rarity because of his untimely death so soon after the signing of the Declaration of Independence. It is considered the most valuable of all the signatures of the 56 men who signed the document. In 1979 a letter signed by Gwinnett sold for $100,000 at auction in New York. (This was the last time a document with Gwinnett's signature was for sale at auction.)
