History of Westchester County, New York, Vol. I
It is said that Lieutenant-colonel Jackson received a musket-ball in his leg; that Major Thomas Henley, one of the Aides-de-camp of General Heath, who had insisted on going out with the expedition, as a Volunteer, was shot through his heart, as he was getting into the float; that Major Hatfield was missing ; and that the Americans lost, in killed, wounded, and missing, fourteen men.'^
There was a wide-spread sorrow expressed for the death of Major Henley, who appears to have been a general favorite ; and the cowardice of those who held back their support was as widely reprobated ; but, in the prevailing temper of that period, although the delinquents were arrested and tried by Courtmartial, nothing appears to have been done with them, beyond the cashiering of one of the Captains.^
