Starting in 2010, Ennis began work on the second volume. He used a similar format, with two storylines, "The Firefly and His Majesty" and "Motherland," being sequels to "Tankies" and "Night Witches" respectively. The other, "Happy Valley", was also the first of these to be published, with art by P. J. Holden. "Happy Valley" deals with a novice pilot assigned to an Australian bomber crew bombing German targets while hoping to stay alive for the three missions remaining until they return home. "Firefly" follows the same British tank crew as they try to take down a powerful German tank. And in "Motherland," the star pilot of the Witches gets transferred into a squadron of fighters defending the Russian front and must learn to once again work well with others.
