Just to be sure, this is the line in the bridge, "the other songs of war"? I just gave it a listen G/B sounds right to me. Basically you play a regular G chord, but the note (B) on the 5th string should be the lowest note of the chord. FYI the differences between C/B, G/B, and Bm are small, and any of them could theoretically be used in a walkdown from C to Am. But based on experience I'd say that G/B would be the most common.
I can barely get through this tune without choking up. Powerful stuff.
