Via Facebook (as I noted many museums are on here and I get their status updates now - lots of interesting factoids!), I ended up on the blog of the James Madison's Montpelier. It was recently Madison's 260th birthday and they posted a brief biography. As I was reading it, I noticed a fact I didn't know - that Madison was the only sitting president to make a battlefield appearance during the Battle of Bladensburg. This intrigued me enough to go looking some and it turned out he didn't take any real leadership role, but he was there:President James Madison and his cabinet were on the battlefield. Madison, though he took no real part in the battle, can be credited with being the only sitting president who served as "commander-in-chief" in battle. Both Francis Scott Key, an aide to the District of Columbia's militia commander, General Walter Smith, and future president and then-Secretary of State James Monroe are credited with changing troop positions.
