Knowing their superior tactics and equipment, how many more soldiers so you need to defeat the Golden Company’s 10k?

warsofasoiaf:

Depends on the soldiers and the terrain. Ideally, attackers want a three-to-one advantage over defenders. However, you’re going the wrong way about it. You don’t want to fight the Golden Company in a setpiece battle. You want to bait them forward, pick off their scouts and foragers ala Marq Piper and get them stressed and starving on unfamiliar soil. Their elephants, horses, and incredibly well-trained troops eat a lot meaning that their supply corps is their weak link.

Thanks for the question, Anon.

And being more cynical – attrition. The Golden Company is 10,000 men and unless they get support, they’re not going to get more. Westeros can raise 400,000 men. If you can inflict significant casualties, even if you’re losing every battle, you will wear them down.
