Everyone is fooling everyone and nobody seems to know it, except the Sargent who wanted to fire on the French at the bridge but was instead arrested because he didn’t follow Austrian discipline. And in this calamity Andrei thinks he will save the Army.
France takes the bridge while the royalty party. Typical.
We end with Bilibin jokingly, yet still correctly (in Andrei’s mind) saying Andrei is a “hero”.
