There is about a paragraph on machine guns, stating that they would have very limited use due to the difficulty of supplying ammunition.

There is no mention of barbed wire.

Does he mention the German flammenwerfer?

Does he mention the German flammenwerfer?

No, I don't think the flamethrower was even developed until sometime into the war. He left Germany a couple of days before WWI started. He does talk about the possibility of Zeppelins "throwing down explosives" and "Aeroplanes".
