Robert, Stubby and Gaston spent the next few months in the Sibille trench, right in the path of the German advance as they desperately tried to move on Paris. This is a retelling of one of the first significant infantry battle of World War I.

This clip explains how World War I came to be a global war after the assassination of Archduke Franz Ferdinand of Austria. Austria-Hungary declares war on Serbia for the assassination, and each country's allies declare war on the opposing countries.

As World War I comes to a close, Robert, Gaston, and Stubby fight until the last minute of the war.

Robert and Gaston discover that there is going to be an incoming gas attack and Stubby goes off to alert everyone.

Colonel Shaw commends Private Trip on his fighting yesterday. He offers to honor the Private by allowing him to bear the regimental colors. Private Trip indicates that he is not fighting for the Colonel and expresses concern that, even after the war, he and his people will not benefit if they win.
