Another goof
At the battle of Petersburg Billy Hazard is waving a Flag saying somthing like "we got them" (I only know the German Version. There he says twice "wir haben sie").
In the first scene he got the Second National or the so called "Stainless Banner", in the next scene he got a Flag that looks like the First National (I don´t think, that it´s exacly this one, but I can´t see what it really could be), afterwards it´s the Second National again.
And I´m also not sure whether the Second National was used during the siege of Petersburg. I think the Third National was in use...!?
