Sailors Maneuvering a Cannon, Possibly a Study for "The Death of Sir John More at Corunna"

Pencil sketch on a gray background. A group of seven men, depicted with minimal clothing, are shown maneuvering a large cannon. The men are positioned around the cannon, with some pushing and others pulling. The man on the left side is leaning forward with his right leg extended backward and his left leg bent in front of him. He has his right hand on the cannon's wheel and his left hand on the barrel. The man to his right is also pushing the cannon, with both hands on the barrel. Two men are positioned on the right side of the cannon, with one standing and one partially obscured. Two additional men are visible on the left side, behind the main group. The man on the far left has short hair and is looking to the right. The other man behind him has longer hair and appears to be leaning on the cannon. Two men are standing behind the cannon, one with his hands on the barrel and the other with his hands on the side. The men are all shown in various poses, conveying a sense of movement and action. The sketch is rendered in pencil with varying levels of detail and shading.
