The Polish Forces came into existence after World War I, and, like all the armies of the newly-independent states which emerged at this time, it was equipped from the dumps of the vanquished. Not until 1937 was a programme of modernisation undertaken, and when war came two years later, the Polsih Army was still basically obsolete; but although lacking in modern equipment and under poor strategic direction, the Polish Army fought bravely.
In 1939, as Europe moved towards war, the Polish gouvernment ordered partial mobilisation in March and August and then, on 30 August 1939, general mobilisation was declared. Along her western frontiers Poland deployed seven armies and a tactical group which accounted for over half her infantry divisions and nearly three-quarter of her cavalry brigades. The remainder of the Army was in the process of formation and was to be used as reinforcements and operational reserves.
