Painting by Conrad Wise Chapman.
“This is a fancy sketch by the artist, and simply designed to show the subterfuge that sometimes had to be resorted to when there was a lack of guns, or there was a delay in receiving them. The fortifications would be prepared, and ‘Quakers’ mounted until the arrival of real guns. The ‘Quaker’ were made of wood and painted black, and at a distance could not be told from the genuine article.” – Conrad Wise Chapman, 1898
