And lastly he decided on a battle that was even riskier than Napoleon's 1812 Russian invasion, Alexander's Indian expedition and Caesar's planned attack on Parthia. In all he went against the teachings of the great three and if he was in the real world, he would have suffered a crushing defeat, an ignominious end and eternal condemnation by scholars of history. But hey, it's Tolkiens fantasy! If he wanted Aragon II to sprout wings and fly, the later would.

Hey, they all would have died anyway if Frodo hadn't succeeded.
