and was utterly unfit to exercise executive functions; it had no means of enforcing its decrees, no revenue, and no munitions of war. The army which it adopted was little better than an assembly of armed men; many were volunteers, and it was decided to enlist men only for seven months. There was little discipline; the officers were for the most part ignorant of their duties and were of the same social standing as their men; and the New England privates, self-opiniated and obstinate, showed little respect for their orders. Washington had not merely to command an army in the field, he had to create one and, what was harder still, to keep it together. [Sidenote: _THE SIEGE OF BOSTON._] Inside Boston life was by no means pleasant. All marketing from the country was at an end, for the town was closely beset by land and the islands were cleared of provisions; no fresh meat was to be had, and the besieged lived alternately on salt beef and salt pork. Attacks from fire-rafts and whale-boats were daily threatened, and fears were entertained that the inhabitants might set fire to the town in order to force the British to leave it.[101] On May 25 the three new generals landed, and the arrival of the reinforcements raised the number of Gage's army to about 10,000 men. Believing that the rebellion would soon be quelled, he issued a foolish proclamation, offering pardon to all rebels who laid down their arms, except Samuel Adams and Hancock, then president of the congress, and threatening those who continued in arms with punishment as traitors. As the insurgents had no ships, while the British had floating batteries and ships of war in the harbour, they could not hope to destroy Gage's army, or reduce it to surrender through famine. Their object was to compel him to evacuate the place and sail off. The peninsula on which the town stands was commanded by hills both on the north and south-east. On the north were the hills of the Charlestown peninsula, which was separated from Boston by the Charles river; it had the Mystic river on its northern side, and was joined to the mainland by a narrow neck. On the south-east it was commanded by the hills of another peninsula called Dorchester Neck. A battery on either the Charlestown hills or the Dorchester heights would have rendered Gage's position untenable; for, independently of any loss which his troops might sustain from bombardment, the British shipping would be drawn from its anchorage, and if he remained he would be practically imprisoned in the town and cut off from supplies. It should therefore have been Gage's first care to shut the insurgents out from those positions.
