Which of the following Revolutionary War battles was most responsible for France deciding to ally with the American colonists against the British?

These battles, occurring in April 1775, were the first military engagements of the Revolutionary War. While they ignited the revolutionary spirit and marked the start of hostilities, they did not provide the decisive victory or the international implications that would persuade France to ally with the colonists.

Fought in October 1780, this battle was a significant victory for the American patriots against Loyalist forces. However, it occurred after France had already allied with the colonists and thus did not play a role in securing that alliance. Its impact was more localized rather than international.

The Siege of Yorktown in 1781 ultimately led to British General Cornwallis's surrender, effectively ending major fighting in the war. While it solidified the American victory, it came after the French alliance was already established following the Battles of Saratoga and thus did not influence France's decision to ally.
