During the second half of 1776, the British had driven Washington’s armies from their strongholds in and near New York City. Washington retreated, moving southeast across New Jersey.
Before his army reached the shores of the Delaware, he sent soldiers ahead to bring together all the boats they could find. When the British arrived at the east bank early in December, the Colonials were safely across. And the British could find only two small boats on a pond.
For the time being, the British gave up the chase. They set up camp at Trenton and at other strongholds along the Delaware.
Washington had the boats on the Pennsylvania side, but that was about all he had. Food was short, and many soldiers were too iii to march. And any day now, the river might freeze, making it possible for the British force to cross into Pennsylvania.
If the struggle for freedom was to continue, Washington had to have a victory. Finally he decided to re-cross the Delaware at Mckonkey’s Ferry. That was nine miles up river from Trenton. Washington’s plan was to cross under cover of darkness on Christmas night and attack the 2,000 to 3,000 British soldiers in Trenton. The general expected that the enemy force would still be celebrating the holiday. On the evening of December 25, Washington gave the orders to cross. It was sleeting snowing, and the river was filled with floating ice. Finally, his force of more than 2,000 men was on the Jersey side. It was after 2 a.m.. In a battle that lasted less than two hours, they defeated the enemy force. Washington had the victory he needed.
The battle of Trenton was very important to Washington because______.

About 1815, when many Americans from the east coast had already moved to the west. trade routes from the ports to the central regions of the country began to be a serious problem, The slow wagons of that time. drawn by horses or oxen, were too expensive for moving heavy freight very far. Americans had long admired Europe’s canals. In New York State a canal seemed the best solution to the transportation problem From the eastern end of Lake Erie all the way across the state to the Hudson River there is a long trip of low land Here the Erie Canal was constructed. After working for several years it was completed in 1825.
The canal produced an immediate effect. Freight costs were cut to about one-tenth of what they had been. New York City, which had been smaller than Philadelphia and Boston, quickly became the leading city of the coast. In later years, transportation routes on the Great Lakes were joined to routes on the Mississippi River. Then New York City became the end point of a great inland shipping system that emended from the Atlantic Ocean far up to the western branches of the Mississippi.
The new railroads made canal shipping not as important as before, but it tied New York even more closely to the central regions of the country. It was easier for people in the central states to ship their goods to New York for export overseas.
Exports from New York were greater than imports. Consequently, shipping companies were eager to fill their ships with passengers on the return trip from Europe. Passengers could come from Europe very cheaply as a result.
Thus New York became the greatest port for receiving people from European countries. Many of them remained in the city. Others stayed in New York for a few weeks, months or years, and then moved to other parts of the United States. For these great numbers of new Americans. New York had to provide homes, goods and services. Their labor helped the city become great
