In the Southern colonies the Revolutionists and Loyalists, waged a war of extermination, the partisans on both sides, seldom gave quarter or took prisoners. At the close of the conflict in Virginia Lord Cornwallis made him a gift of a handsome sword, accompanied by a letter conferring on him the rank of Major Brevet. Whilst Coffin was attached to Cornwallis, he was able to be of great service to him, but the bravery, not to say the extraordinary sagacity mingled with audacity of one man, could not save the army. Lord Cornwallis' army cooped up in Yorktown by a superior army of French and Americans, and blockaded by a French fleet, was in danger of starvation, and Coffin stood almost alone in successful forays, in which he frequently eluded the whole American and French army, and returned laden with the fruits of his success. In one of these raids he accidentally came to the house of a wealthy planter whose daughter was to be married that day. He quietly surrounded the house with his troops and knocking at the door, sent in word that he wished to speak with the proprietor. On presenting himself, the gentleman was courteously made aware of his condition. He was told not to make any noise, but to order sufficient turkeys, ham, wine and other provisions to be put up, to satisfy his men; if this was done no harm would happen, but on the contrary, if any resistance was attempted, everything and everybody in the house would be destroyed. Coffin's character and resolution were well known, so the planter thought it best to graciously comply with the mandate. A large quantity of provisions was thus secured. Captain Coffin supped with the wedding party, danced with the bride, and left in safety, taking care that no alarm should be given, and reached Cornwallis without accident by daylight.
