who fought in the first battle of ypres

Most people have either watched or got word of the movie Wall-e. It was a a cute film, set way into the longer term, concerning the adventures of an little robot that was left out that is known to clear in the mess forgotten by humans. The humans are living in space when they wait for a earth to become re-habitable to enable them to all return. Wall-e meets another robot called EVE, who may have been shipped to earth to hunt out any signs and symptoms of new life (growing plants), falls in love and follows her into space where they're linked to lots of antics before Wall-e eventually returns to earth with EVE, the humans follow and they also go about rendering it a great spot to live again.
