Final answer:
Dolley Madison did indeed save national treasures like the portrait of George Washington as the British burned Washington, DC during the War of 1812. The given statement is true.
Step-by-step explanation:
The statement that President Madison's wife, Dolley, managed to save many national treasures as the British approached Washington, DC and burnt the capital city is true. During the War of 1812, the British attacked Washington D.C., setting fire to public buildings such as the Capitol and the White House.
Dolley Madison played a heroic role as she directed the removal of valuables from the White House to save them from destruction, including the famous portrait of George Washington by Gilbert Stuart. The British invasion resulted in the burning and gutting of numerous buildings, but thanks to Dolley Madison's efforts, some important national treasures were preserved.
