Enough to man and replenish the 3rd and 4th Polish Infantry Divisions and create the 1st Polish Armored, which is already a lot (this also includes the soldiers of the Highland Brigade evacuated from Norway).
The Polish Army Corps will be bolstered by Anders' Army, so add more men to the tally.
All of this will constitute the Polish Army Corps (3rd, 4th, 5th, 6th Infantry Divisions [this one won't be formed until 1943], 1st Armored Division, 1st Parachute Brigade) which will not be deployed in France, but elsewhere...
Not to mention the Polish Air Forces which also had been bolstered.
