The negotiations for surrender were complicated by two issues. When American forces surrendered at Charleston in 1780, they were not granted customary terms of capitulation that included flying colors and the playing of an enemy tune. Washington insisted that these terms be applied to the surrender of the British army at Yorktown, his negotiators pointing out that the defenders had in both instances acted with valor. The second issue concerned the disposition of Loyalists in the British camp. This issue was finessed with the addition of a clause to the terms that allowed one British vessel, the sloop "Bonetta", to be sent without any sort of inspection to carry dispatches from Cornwallis to New York; Americans, suspecting that either runaway slaves or Loyalists might be aboard, were prevented from searching the vessel.
