Revolutionary War Soldier in Gritty Battle Scene

the prompt

A young American Revolutionary War soldier on a smoke-filled, muddy battlefield at dawn. He loads his flintlock musket, bites a gunpowder cartridge, then aims and fires. An explosion throws him to the ground. He rises, disoriented but determined, amidst distant musket fire and cannon smoke. He runs past fallen soldiers, then stands observing the chaotic battle. Cinematic, gritty realism, wide shots and close-ups, handheld feel for action, slow-motion for impacts.
