ications guarded the southern approaches to Charleston Harbour. The British plan was to launch a two pronged attack - Clinton with 2,000 men would wade across shallows linking Sullivan's Island to Long Island, while Parker bombarded the fortifications from the sea. However, on the day of the attack, 28 June, the weather and the seas were not as the British had expected them to be. The water between Long Island and Sullivan's Island was far too deep to wade, while Parker was unable to get his ships as close as he had expected and came under a devastating fire from the American guns. When night fell the British ships were forced to withdraw, having suffered serious damage. With the failure of the attack on Charleston British activity in the south ended for two years.on New Yorkmain British army began the year blockaded in Boston. Outside the city Washington had managed to put together a formidable army of over 17,000 men by February. He had also built up his stocks of artillery and powder to the level where he could carry out a proper siege. In Boston the British army had endured months of boredom punctuated by occasional alarms, and discipline in the army was poor. General Gage had now been replaced by General William Howe, who was had been given permission to evacuate Boston if the situation justified it. Howe was convinced that he should leave, but did not have enough ships for a proper evacuation and was waiting for more transports when, on 2 March, the Americans began their artillery bombardment. They then captured the Dorchester Heights, overlooking Boston Harbour. The British position was now untenable, and Howe decided to withdraw in the ships he already had. After destroying the military supplies in the city, Howe and his army departed for Halifax on 17 March. The Americans let him go in peace in return for an agreement not to burn the city before he left.was itself a poor location for an army. Supplies were still limited and the weather appalling, but Howe settled down for months while he planned his attack on New York. Now Boston was secure, the Americans were concentrating their forces around New York and building up the defences. Howe decided to wait until Clinton and the army in the south could join him.finally decided to move in June. The British fleet was sighted on 29 June and the British army landed on Staten Island on 3 July. After Clinton arrived in mid-August Howe had 32,000 men under his command. Washington was faced by a serious problem. He was outnumbered, had limited supplies and no naval support. He had two main islands to defend - Long Island and Manhattan Island. If he split his forced between the two islands, Washington was well aware that they could be split in two and defeated in detail, but he had little or no choice. The Brooklyn Heights on Long Island overlooked New York. If they fell to the British then the city would be fatally exposed. Washington posted troops around Brooklyn vi...
