The Hour of Battle poster is the second piece in The Fort Mifflin Collection trilogy and represents the moment when the quiet tension surrounding the 1777 Siege of Fort Mifflin erupts into open conflict. While The Watch poster focuses on the uncertainty and responsibility carried by those defending the fort before the fighting begins, this design captures the intensity, courage, and chaos of the battle itself.

‍ ‍The poster is intended to portray the experience of the Continental defenders as they faced the overwhelming force of the British Royal Navy and Army positioned against them. Rather than focusing on a single documented moment, the image represents the collective experience of the soldiers who stood on the fortifications during the bombardment — loading muskets, firing through smoke, enduring cannon fire, and continuing the defense despite impossible odds.

‍ ‍The composition emphasizes the scale and brutality of the siege while maintaining historical respect for the men who defended Fort Mifflin. The goal is not to portray a heroic battle scene in the traditional sense, but to communicate the exhaustion, determination, and sacrifice of those who held the fort during one of the most intense bombardments of the American Revolution.
