Ah, but those Japanese sailors were not under fire; what's more, they were performing something like a ceremonial obligation.   

I don't doubt that thoughtful men like Pickett were impressed, even moved, by the sacrificial courage of the enemy, but the idea that the hundreds of Confederate riflemen who *were* cheering did so for that reason - and not for the obvious and predictable one that they could see the attackers being stopped in their tracks, that's just too much for me to believe, no matter how one might wish it were so.
