Story on the back:

"The Martians never let any soldiers get close to them, blasting any approaching Earthmen with their death rays. However one of the aliens was so interested in watching a burning building that he never noticed a group of soldiers sneaking up behind him, until it was too late Carrying a huge fishing net, a couple of the Earth fighters wrapped it over the surprised victim. The spaceman lashed out at the soldiers, trying to grab one through the net. A quick jab with a bayonet quieted the alien and he was carried off to Earth's military headquarters. There, trained specialists would attempt to break the language barrier and communicate with the captured Martian."
