Final answer:
The Battle of Trenton was the surprise attack that boosted Patriot morale and secured needed supplies. It was a key victory for the Continental Army during a difficult time in the war. This victory also helped to pave the way for the crucial French alliance after the Battle of Saratoga.
Step-by-step explanation:
The name of the surprise attack that boosted Patriot morale and helped them secure much-needed supplies was the Battle of Trenton. This battle took place on December 25 and 26, 1776, when General George Washington famously crossed the Delaware River and led his troops in a surprise attack against the Hessian forces. The victory at Trenton was significant because it boosted morale at a time when the war had been going poorly for the Americans, and it also provided the Continental Army with vital supplies and a much-needed victory.
In contrast, the Battle of Saratoga is considered the major turning point in the War for Independence. This victory convinced the French to recognize American independence and form a military alliance with the new nation, providing crucial financial and military support that proved decisive in the ultimate defeat of Great Britain.
