The correct answer to this open question is the following.
The problems that the Continental Army face at Saratoga were so many and of different nature. But basically, we can sum them up in three: the lack of money, problems of transportation, and poor organization. That is why, under these deplorable conditions, the Continental army had to use the Quartermaster Department to help solve some problems. It asked the states to provide for supplies. Patriots responding sending blankets, food, and other supplies by the effort was not enough. There was no good communication and organization between the Quartermaster and the government of the colonies.
General George Washington knew the Continental Army soldiers were poorly trained and had minimum combat experience. That is why Washington called the help of Prussian military Official Baron Von Steuben during the winter of 1778 in Valley Forge. This Prussian military really helped to train the American troops.
