This short, nominated for an Academy Award, was made by George Pal and concerns an invasion by mechanized war machines in a place obviously modeled on Holland, which was under occupation by the Nazis at the time. It is a tribute to the ability of humanity to persevere against the worst imaginable events and no only survive, but thrive. It is incorporated into The Puppetoon Movie and is a wonderful piece of work. The ending is glorious! Most highly recommended.
