Following the Battle of Bunker Hill, the siege was effectively stalemated, as neither side had either a clearly dominant position, or the will and materiel to significantly alter its position. When Washington took command of the army in July, he determined that its size had reduced from 20,000 to about 13,000 men fit for duty. He also established that the battle had severely depleted the army's powder stock, which was eventually alleviated by powder shipments from Philadelphia. The British were also busy bringing in reinforcements; by the time of Washington's arrival the British had more than 10,000 men in the city.
