At the head of between six and seven hundred men, he advanced two hundred miles up the river, and destroyed the villages and corn-fields on its head branches.

Here too the Indians were unable to resist the invading army.
After one unsuccessful skirmish, they abandoned their villages to a destruction which was inevitable, and sought for personal safety in their woods.
On receiving the communications of General Sullivan, congress passed a vote approving his conduct, and that of his army.

That approbation, however, seems not to have extended beyond his conduct in the Indian country.

His demands for military stores for the expedition had been so high; in his conversations with his officers, he had so freely censured the government for its failure to comply with those demands; in general orders, he had so openly complained of inattention to the preparations necessary to secure the success of the enterprise; that considerable offence was given to several members of congress, and still more to the board of war.

From the operation of these causes, when Sullivan, at the close of the campaign, complained of ill health, and offered, on that account, to resign his commission, the endeavours of his friends to obtain a vote requesting him to continue in the service, and permitting him to retire from actual duty until his health should be restored, were overruled; and his resignation was accepted.
