In the second part of this story arc, the League, scattered to various parts of the armed conflict, seek to stop the German advances that are being aided by technology provided by Vandal Savage, a time traveling immortal with delusions of world conquest. Superman, Hawkgirl and the Flash aid the Allied forces as they struggle against the Germans in the air and on the ground. A nice scene for this viewer involved the introduction of the flying squadron collectively known as the Blackhawks, a tip of the hat to the comic book characters who had their own series in the past. It's good to see that the artists and writers of this show took the time to look up what the characters looked like as well as their individual names.
The other members of the League, in other parts of conflict, continue to do their part in helping the Allies with various degrees of sucess. The episode ends on a cliffhanger ( as usual) with everything pointing to a rousing concluding final part.
A great part of this story arc that has some great action scenes balanced by some touching scenes of drama.
