I am writing a steampunk novel and am working on a scene where an enemy quickly overwhelms and destroys a US airship. The enemy has flying gyro sleds and a large airship of their own that is armed with rockets, air cannon and possibly electricity weapons. They need to destroy the US airship's communication and then quickly destroy the airship itself.
I am aware that during WWI, due to bullet holes leaking too slow, the Brits had trouble "shooting down" the German airships until they had incendiary ammunition but that worked because the Germans were using hydrogen. How would you all overwhelm and take down a helium airship?
Answers simply need to be plausible. I write from the H. G. Wells view point when it comes to tech.
Some specific background: Target airship is USAS Nathan Hale, a Military Airship designed primarily to fight other airships, but since Fixed wing aircraft has not been seen yet unprepared for an attack of flying Bob Sled like craft. Terrain: Over the American-Canadian border, near the St. Lawrence Seaway.
