The Mills That Fed the Army
When we talk about Brandywine, we talk about the battle — the flanking movement, the American retreat. What we rarely discuss is why the British needed to take this particular ground.
The Brandywine Creek above Wilmington was the most productive milling corridor in North America in 1777. When Washington positioned his army there, he was defending not just the road to Philadelphia but his supply system: the flour, powder, and paper mills that fed and armed the Continental Army. When Howe captured Wilmington after Brandywine, he captured the mills too. Nine months of British supervision. When Clinton evacuated in June 1778, they went back to the Continental Army.
The du Pont family arrived in 1802 and found industrial infrastructure refined over a century. The Brandywine Valley's industrial story began with the Revolution, not after it.
