and the British plan was changed accordingly.second set of instructions was issued on 21 March. The war in the colonies was now to take a back seat. Clinton was to abandon Philadelphia, and return to New York, from where he was to send 5,000 men to attack St. Lucia, another 3,000 to reinforce the Floridas, now of sudden importance, and to detach yet more men to defend Halifax. The British aim was now to go on the offensive in the West Indies, while fighting a purely defensive war in America.From Philadelphiafor the British, Washington also had his problems over the winter of 1777-8. On 21 December 1777 Washington and his 11,000 men had marched to Valley Forge, where they had made camp for the winter. Washington had picked Valley Forge for several convincing reasons. First, it was well positioned to watch the British, eighteen miles to the southeast at Philadelphia. Second, it was an easily defensible location on high ground. Third, it was in a largely unpopulated area and Washington did not want to alienate the population of Pennsylvania by inflicting a wintering army on them. Finally, there was some hope that supplies would be easier to find in Pennsylvania than had been the case in previous winters. However, the location also had its problems. There was little or no food present when the army arrived (the British had already searched the area earlier in the year), the remoteness of the location made it hard for supplies to reach the army, and when the army arrived there were no building for them to use. Across January and February the army faced near starvation, boredom and poor discipline.began to change towards the end of February. First, the supply situation was improved by Nathanael Greene, head of the quartermasters department. He despatched foragers into neighbouring states and food finally reached the camp in decent quantities. Second, the discipline problem was relieved by the arrival of Frederick von Steuben, a Prussian volunteer, who reached Valley Forge towards the end of February. Although not the experienced soldier he claimed to be, Steuben turned out to be a highly proficient trainer of soldiers. When Washington and his army emerged from Valley Forge it was a much more proficient force than when it had entered it.finally prepared to leave Philadelphia in June. His main problem was the sheer size of his column. As well as 10,000 soldiers there were 1500 wagons and all of the support services that the army required. When fully stretched out on the march this supply train would cover twelve miles. Clinton finally moved out of Philadelphia at 3 in the morning on 18 June. His army crawled towards New York, covering only thirty-five miles in the next six days. Over the same days Washington managed to move his army, of a similar size but relatively unencumbered, fifty-seven miles. Despite this rapid march, there was no consensus in the American camp on what to do once they had caught up with the British. Advic...
