During Cornelius's stay in Fort Drake Borough, it was attacked by Spanish soldiers. When the British were incapable of defending the fort, the commander made a deal with Cornelius: the fort would pass to his property so the British wouldn't be responsible if the Spanish took it. Cornelius agreed, and then popped some corn to make it sound like shots, which made the Spanish troops run away.
Cornelius renamed the fort as Fort Duckburg and turned it into a trading camp for hunters. Several people began to settle down and form families, and Cornelius himself started a farm of his own. A village was formed in Duckburg, with Cornelius as the leader.In modern times, Duckburg has a statue of Cornelius Coot holding corn. It can be seen in several comic stories, and also had a cameo in the DuckTales episode "Ducks on the Lam". A real-life version of the statue was also built in Mickey's Toontown Fair. The Toontown version includes the legend:
This Is Old Cornelius Coot
Who Turned His Corn Crop Into Loot
And Founded Mickey's Toontown Fair
To Him We Dedicate This Square.
