The Thunderbirds' time in Salerno hits some very big bumps, particularly for Capt. Sparks, whose early days as the unit's commander are also explored.

With their flank exposed, the Thunderbirds face a brutal standoff with the Germans while defending Anzio. Sparks faces discipline for his actions.

A rebuilt E Company ships off to France. Initially it's a welcome break, but it soon brings another impossible mission. Sparks receives high honors.

As the Allies close in on increasingly desperate German forces, the Thunderbirds bear witness to the atrocities of their enemy, and their fellow troops.
