After a few days he grew more cheerful, and said he had changed his mind.

Wayne set him at liberty, and he not only served valiantly as a scout through the campaign, but acted as Wayne's interpreter.

Early in July he showed his good faith by assisting McClellan in the capture of a Pottawatamie chief.
An Unexpected Act of Mercy.
On one of Wells' scouts he and his companions came across a family of Indians in a canoe by the river bank.

The white wood rangers were as ruthless as their red foes, sparing neither sex nor age; and the scouts were cocking rifles when Wells recognized the Indians as being the family into which he had been adopted, and by which he had been treated as a son and brother.

Springing forward he swore immediate death to the first man who fired; and then told his companions who the Indians were.
The scouts at once dropped their weapons, shook hands with the Miamis, and sent them off unharmed.
Last Scouting Trip before the Battle.
Wells' last scouting trip was made just before the final battle of the campaign.
