Hitler probably also experienced gas (not sure his generals did, though). People forget that he was actually a decorated NCO, from WWI (which had a lot to do with his terrible attitude, later in life).

It was fairly worthless, militarily. High risk, big mess, no real tactical advantage, and it just pissed everyone off. Its only real efficacy would have been for bombing civilian targets, and I don't think they had the delivery mechanisms.
