Often Light troops were the answer to Elephants, getting in close and attempting to hamstring them.
In the game you can train up your light troops with anti elephant skills.
One of the subtlties is that whils you can see enemy troops and get info from the tool tip. You never get info on the skills they have.
So that innacuious looking skirmisher unit may well be elephant killers
It can come as quite a surprise.
So you need some auxila to support the elephants , then the enemy needs some heavy cav to counter the auxilla and so on
