As a result of the battles of Trenton and Princeton during the American Revolution, more soldiers enlisted in the Continental Army.

Explanation:

The battles of Trenton and Princeton were two very important battles that occurred in New Jersey during the late 1776 and early 1777, in which the Continental Army under George Washington defeated professional Hessian and British forces.

Thus, during the Battle of Trenton on December 26, 1776, the forces under the command of Washington defeated the Hessian troops, made up of German professional mercenaries. In turn, on January 3, 1777, the same American forces defeated the British at Princeton, demonstrating to the American people that the Continental Army was competent and fierce in battle, in turn encouraging many more patriots to join the cause.
