16. Before daybreak on the 31st of December, Montgomery attacked the Lower Town. At the first discharge Montgomery fell dead. The men, heartbroken at their loss, retreated above the city. Arnold had meanwhile fought his way into the Lower Town, but was severely wounded and borne to the rear. Captain Morgan led his brave band along the narrow streets until he was overwhelmed and compelled to surrender. Arnold retired to a point three miles above the city. The small-pox broke out in the camp; and in the following June the Americans evacuated Canada. CHAPTER XXIII. THE EVENTS OF 1776. At last came the king's answer to the appeal of Congress. The petition of the colonies was rejected with contempt. By this tyrannical answer the day of independence was brought nearer. Meanwhile, General Howe had succeeded Gage in command of the British troops in Boston. 2. All winter long the city was besieged by Washington. By the first of spring, 1776, it was resolved to seize Dorchester Heights and drive Howe out of Boston. On the night of the 4th of March a detachment under cover of the darkness reached the Heights unperceived. The British noticed nothing unusual; but, when morning dawned, Howe saw at a glance that he must carry the American position or abandon the city. He ordered his men to storm the Heights before nightfall. [Sidenote: =The British driven from Boston.=] 3. Washington visited the trenches and exhorted his men. It was the anniversary of the Boston Massacre. A battle was momentarily expected; but while the British delayed, a storm arose and rendered the harbor impassable, and the attack could not be made. Before the following morning the Americans had so strengthened their fortifications that all thoughts of an assault were abandoned. Howe found himself reduced to the extremity of giving up the capital of New England. 4. After some days there was an agreement between Washington and the British general that the latter should retire from Boston unmolested on condition that the city should not be burned. On the 17th of March, the whole British army sailed away. The American advance at once entered the city. On the 20th, Washington made a formal entry at the head of the triumphant army. The country was wild with delight. Congress ordered a gold medal to be struck in honor of Washington's victory over the enemy. 5. In a short time, the commander-in-chief repaired with the army to New York. General Lee pressed forward with the Connecticut militia, and reached that city just in time to baffle an attempt of Sir Henry Clinton, who next sailed southward, and was joined by Sir Peter Parker and Lord Cornwallis with two thousand five hundred men. The force of the British was deemed sufficient to capture Charleston. [Sidenote: =British Repulsed at Charleston.=]
