Poland

A small German force begins to cross the Vistula just south of Warsaw. The Bzura battles are now going badly for the Polish forces. The heaviest fighting will be over by Sept 15 but some engagements will continue until the 19th. Although the Germans will take their largest single haul of 150,000 prisoners in this battle, by Sept 19 units of 2 Polish brigades and elements of others will manage to escape to Warsaw.

The last meaningful flights by the Polish Air Force are undertaken in an effort to supply the besieged city of Modlin.
