Amid the Revolution's escalating conflict, Mathews' mayoral tenure underscored New York City's position as a center of tension.

On June 22, 1776, Mathews was arrested on suspicion of involvement in the Hickey Plot to assassinate George Washington, highlighting the era's espionage activities.

This pivotal decision was followed by the adoption of the Declaration of Independence on July 4, outlining the reasons and principles for independence. While Independence Day is marked on July 4, the actual vote occurred on July 2.

In New York City, a key urban and strategic center, these July events were crucial. The city's significant port and location made it a prime target in the American Revolution. Following independence, British forces quickly captured New York City, profoundly impacting its residents and marking a challenging period of military occupation and conflict. This period was pivotal for New York's role in the struggle for independence and its place in the American Revolution narrative.

Authored chiefly by Thomas Jefferson, it outlined the Thirteen Colonies' reasons for separating from Great Britain, emphasizing individual rights and self-governance. Independence Day, marking this ratification, is now a national U.S. holiday.

For New York City, a strategic port and key battleground in 1776, this ratification brought immediate challenges.

This defiant act went beyond symbolism; the lead statue was melted into 42,000 musket balls for the Continental Army, blending political dissent with practical support for the war effort. The July 9 event at Bowling Green epitomizes the rejection of British authority and their dedication to independence, embodying the revolutionaries' spirit and ingenuity during the American Revolution.

1776: On August 27, the Battle of Long Island, or Battle of Brooklyn, marked the first major military conflict post-U.S. independence declaration.

However, Washington's successful management of a strategic retreat saved the Continental Army from total defeat, maintaining its viability for future battles. This event underscored American resilience and strategic skills, setting the course for New York City's role in the Revolutionary War's remaining years.

1776: In a pivotal move post-Battle of Long Island defeat, General Washington masterfully orchestrated the Continental Army's stealth retreat to Manhattan on the night of August 29-30, 1776.

Consequently, it allowed the revolutionary forces to persist in their quest for American independence, marking a significant strategic victory in the early stages of the struggle.

1776: On September 15, during the American Revolutionary War, British forces captured lower Manhattan following the Landing at Kip's Bay.

Following the fire, the British detained many suspected individuals, leading to the arrest of American soldier and spy Nathan Hale on September 22, known for his last words, "I only regret that I have but one life to lose for my country." The Great Fire significantly impacted New York City, initiating extensive rebuilding and urban development that shaped its post-independence modernization.

1776: On September 22, a pivotal moment in the American Revolutionary War and American history occurred with the execution of Nathan Hale. A Continental Army captain and spy, Hale was captured and executed by the British for espionage in New York City, then under British control post-Battle of Long Island.
