20th Of September

"...Colonel [William] Davie, with unprecedented boldness, with a command not exceeding one hundred and fifty men all told, on the 20th of September, turning the right flank of the British army by a circuitous march, fell upon three hundred or four hundred of the enemy at Wahab's plantation. The attack was made at daylight. The surprise was complete.

The enemy left fifteen or twenty dead on the field and had some forty wounded. Davie got off safely with the captured horses and had only one man wounded. The enemy at once caused the farm buildings which belonged to Captain Wahab, then a volunteer with Davie, to be laid in ashes. Davie brought off ninety-six horses and their furnishings, and one hundred and twenty stand of arms, and arrived in camp the same afternoon, having marched sixty miles in less than twenty-four hours, including the time employed in seeking and beating the enemy. That evening Generals Sumner and Davidson arrived at his camp with their force of one thousand badly equipped militia.
