He would even have no day, not one hour, because
1 The forces of the Pas de Calais were useless in Normandy, because they were qualitatively and quantitatively weaker than the forces in Normandy who were weaker than the Allies .
2 It was logistically impossible to transport the PdC forces to Normandy on D Day .
3 Thus they had to be in Normandy before Dday ,but without them , the Allies would land easily on the Pas de Calais .
To summarize :
The Allies had category A forces
The Germans had category B forces in Normandy and category C forces on the Pas de Calais .
B and C could not win against A .
