Answer: Her Grandfather, I think
This question is actually a matter of opinion. Some would say he shows strength by knowing he has to sacrifice six of his men when he has already lost so many. They say it shows he's a strong character and a determined leader. That he's willing to sacrifice anything for his cause. That's a very strong character trait. Some, however, would say it shows he's weak. Not only did he know it wouldn't be him who died, he also didn't tell his remaining men. He let six of them die. He knew they would and he did not say anything. I guess whatever side you take is up to you.
