I did a search on the forums, and it doesn't appear that someone has asked this question before.
George Washington passed away in 1799 as a result of a sudden illness. He was only 67 at the time of his death. It is possible he could have lived to his early 80s like Franklin and Thomas Jefferson, or even in his 90s like John Adams. In other words, he could've lived to 1815 (83 years old) or even to 1822 (90 years old). I would imagine that he would stay out of politics and stay on his farm for most of his life. However, a question that does spring to mind is what happens when the War of 1812 breaks out? I can't imagine him not wanting to protecting the Union in some way. For example, maybe he will donate some of his money and slaves for the war effort? Maybe he will command Virginia's militia against the British (When they march on Washington)? Washington would be in his 80s at the time, so it is hard to say if he could command troops at that age. However, I would imagine that even the word that Washington was coming to join the fight might've prevented the Americans from losing the Battle of Bladensburg or even having the White House burn to the ground. For example, the American troops might hold the ground in the hopes that Washington could relieve them from the British attack.
What are your thoughts? What impact, if any, would George Washington have on the War of 1812?
