people but I don't think so.
He didn't like to drink, he hated it.

But otherwise, you have a point.

On the other hand, leadership in the ancient world and in the 19th century meant different things. A classical general was expected to lead his men into battle from the front. In Grant's day, an army commander would be considered marginally insane if he ventured within range of enemy guns. A drunk riding towards the enemy with a sword would be disheartening, but a drunk in a farmhouse somewhere behind the lines is "out of sight, out of mind".
