During the Revolution the British complained that colonial sharpshooters unfairly targeted British officers.
It was a head of the snake scenario. Once the British officers went down the ranks didn’t know what to do.
Don`t forget Johnson`s 1758 Mohawk sharpshooters and 1777 Morgan`s Riflemen [Murphy`s double kill at 300 yards] at Saratoga and other battles:
“1758 JOHNSON`S MOHAWK SHARPSHOOTERS FUSILLADE THE FRENCH 1758 July 8 From the side of Mt. Defiance ``Mohawks fired upon them [French] and we see them run into their fort and within their breastwork. And after a small space of time they ventured out to work again and after the engineer had viewed the fort he ordered them all to return back again...and the Mohawks went upon the same mountain [Defiance] after we came down and fired and shouted to alarm the French and then came down...`` 419 [One Mohawk oral tradition says that the Mohawks had rifled muskets.]-from “Native American Tales and Trails on the Northeast Warpath of the Nations”, pp.124-131
“As the battles around Saratoga raged, the British, having been pushed back, were being rallied by Brigadier General Simon Fraser. General Benedict Arnold (still a good guy at the time of Saratoga) rode up to General Morgan, pointing at Fraser and shouted “ . . . that man on the gray horse is a host in himself and must be disposed of”. Morgan gave the order for his best marksmen to try and take him out. Timothy Murphy climbed a nearby tree, finding a comfortable notch to rest his double barreled rifle, took careful aim at the extreme distance of 300 yards, and squeezed off a shot. General Fraser tumbled from his horse, shot through the midsection. He was taken from the field and died the next day. Another British Senior officer, Sir Frances Clarke, General Burgoyne’s chief Aide-de-Camp, galloped onto the field with an important message. Murphys second shot dropped him. He was dead before he hit the ground!
