Timothy Newell kept a very vivid diary of life in Boston in 1775 and 1776. He started the entry below on this date, 250 years ago, by copying the “sundry papers lent me…relative to the Siege and Evacuation of Boston in 1775…”
To the Commanding Officer at Roxbury
March 8, 1776
As His Excellency Gen Howe is determined to leave the Town with the troops under his command, a number of the respectable Inhabitants, being very anxious for its preservation and safety, have applied to General Robertson for this purpose, who at their request have communicated the same to his Excellency Gen Howe, who has assurred him, that he has no intention of destroying the Town, unless the Troops under his command are molested, during their embarkation, or at their departure by the armed force without; which declaration he gave General Robertson leave to communicate to the Inhabitants. If such an opposition should take place, we have the greatest reason to expect the Town will be exposed to entire destruction. As our fears are quieted, with regard to General Howe’s intentions, we beg we may have some assurances, that so dreadful a calamity may not be brought on by any measures without. As a testimony of the truth above we have signed our names to this Paper, carried out by Mess Thomas and Jonathan Amory, and Peter Johonnet, who have at the earnest entreaties of the Inhabitants, through the Lieu Governor solicited a flag of truce for this purpose.

In March 1776, a quiet hill overlooking Boston Harbor became one of the first turning points of the American Revolutionary War. Dorchester Heights, rising above the southern approaches to Boston in what is now South Boston, played a decisive role in forcing the British Army to evacuate the city. The dramatic occupation and fortification of the Heights by American forces under General George Washington transformed a long, grinding siege into a strategic victory that reshaped the war’s momentum.
After the battles of Lexington and Concord in April 1775 and the bloody clash at Bunker Hill in June, British forces under General Thomas Gage and then William Howe found themselves effectively trapped in Boston. Surrounding militia units from Massachusetts and neighboring colonies formed a loose ring around the city, beginning what became known as the Siege of Boston. When George Washington arrived in July 1775 to take command of the newly formed Continental Army, he inherited a force that was determined but poorly supplied and short on artillery.
Throughout the fall and winter of 1775–1776, Washington searched for a way to break the stalemate. A direct assault on Boston would have been costly and risky. Instead, he looked to geography. Dorchester Heights, commanding sweeping views of the harbor and the city, offered a strategic advantage. If American forces could fortify the Heights with cannon, they would threaten both the British fleet and the troops stationed in Boston. Control of this high ground would make the British position untenable. The British Navy had encouraged British General Howe (now commanding the British forces in Boston) to take the position due to the Navy’s vulnerability if the Americans were able to command the heights with artillery. Howe underestimated the importance of the heights and also believed the Americans lacked the proper artillery and strength to hold it.

The key to Washington’s plan lay in artillery. In late 1775, Colonel Henry Knox undertook an audacious mission to transport heavy cannons captured from the British at Fort Ticonderoga in upstate New York. Over the winter, Knox and his men hauled approximately 60 tons of artillery—an operation later dubbed the “Noble Train of Artillery”—over 300 miles of frozen rivers and snow-covered terrain to Cambridge, Massachusetts.
These cannons provided Washington with the firepower necessary to implement his strategy. By early March 1776, conditions were ripe. The ground was still frozen, making it easier to move heavy equipment and but would challenge their skills at building fortifications.
On the night of March 4, American troops moved silently toward Dorchester Heights. Under the cover of darkness and diversionary bombardments from other positions, they began constructing fortifications with remarkable speed. Using pre-prepared materials—fascines (bundles of sticks), chandeliers (wooden frames filled with earth), and hay bales—they built defensive works capable of withstanding British cannon fire.
By dawn on March 5, the anniversary of the Boston Massacre, British sentries were stunned to see formidable American fortifications atop the Heights, bristling with cannon aimed at the city and harbor. General Howe reportedly exclaimed that the rebels had accomplished more in one night than his army could have done in months. The strategic implications were clear. From Dorchester Heights, American artillery could rain fire down on British ships and troop positions. The Royal Navy, essential to British supply and mobility, was now vulnerable. Remaining in Boston was a risk that Admiral Molyneux Shuldham was not willing to take and pushed Howe to respond quickly.
General Howe initially planned a counterattack to dislodge the Americans. However, a fierce storm on March 6 disrupted preparations and made an amphibious assault difficult. Also, Washington got word of the planned British assault and increased his manpower on Dorchester Heights to nearly 6,000. The memory of heavy British casualties at Bunker Hill also weighed heavily. Dorchester Heights were even stronger and more defensible than Breed’s Hill had been the previous year.

Facing the prospect of severe losses and an increasingly precarious situation, Howe reconsidered. Negotiations—informal and indirect—suggested that if the British evacuated Boston without destroying the town, American forces would not attack during the withdrawal.
On March 17, 1776, British troops and Loyalists began evacuating the city. More than 11,000 soldiers and nearly 1,000 Loyalists boarded ships and sailed to Halifax, Nova Scotia. The Siege of Boston was over, and the city was firmly in American hands for the remainder of the war.
The occupation of Dorchester Heights marked the first major strategic victory for the Continental Army under Washington’s leadership. It demonstrated the effectiveness of coordinated planning, logistical ingenuity, and the intelligent use of terrain. Rather than launching a costly frontal assault, Washington had leveraged geography and artillery to compel the enemy’s withdrawal.
This victory also boosted American morale at a critical time. The war was far from won—indeed, it would intensify dramatically later in 1776 with British campaigns in New York—but the successful eviction of British forces from Boston showed that the Continental Army could achieve meaningful results.
Moreover, Dorchester Heights solidified Washington’s reputation as a capable commander. His cautious but decisive approach, combined with Knox’s logistical triumph, set a pattern for future operations. The event underscored the importance of high ground in military strategy, a lesson that had already been evident at Bunker Hill but was applied with even greater effect in March 1776.

Emerging Revolutionary War welcomes guest historian Drew Palmer. A biography follows at the end of this post.
What does it look like when veteran soldiers do not want to fight anymore? When morale plummets and the realities of war take their toll on men. This is exactly what happened to 150 men in the Maryland Line of the Continental Army in the late summer of 1780.
The 1st Maryland Regiment holds the line at the Battle of Guilford Courthouse, March 15, 1781
The continental regiments of Maryland that made up what became known as the “Maryland Line” or “Old Line State” had earned the reputation as a reliable, brave, and disciplined fighting force as early as 1776 after their actions in the Battle of Long Island.1 At the Battle of Camden on August 16, 1780, the 1st and 2nd Maryland Brigades offered a stout defense as Gen. Charles Cornwallis’s British force crashed into Continental soldiers from Maryland and Delaware. In the end, though, Maj. General Horatio Gates’s Southern Continental Army was completely routed from the field, with many of the Maryland Continental troops taken prisoner and held in the small village of Camden after the battle.2
The village of Camden, South Carolina, was an unpleasant place to be after the battle. The crowded conditions and brutal summer climate of South Carolina began to produce sickness amongst Cornwallis’s men and the American prisoners that were held in Camden. To prevent further sickness from spreading, Cornwallis decided to split the American prisoners held at Camden into divisions of around 150 men. These divisions were guarded by small detachments of the British army and marched from Camden to Charlestown, South Carolina.3 One detachment of the British 63rd Regiment of Foot escorted 150 prisoners of the 1st Maryland Brigade captured at Camden. The division made it to Thomas Sumter’s abandoned plantation at Great Savannah, about 60 miles northwest of Charleston. As the Maryland prisoners and their British guards halted for the night, militia commander Francis Marion received word from a Loyalist deserter that the Marylanders were nearby and decided to ambush the British element in hopes of freeing the Maryland prisoners.4 In the early morning hours of August 25, 1780, Marion’s militia attacked.

They are all reasons officers gave for asking for furloughs during the winter encampment of 1779-1780.
While the regulations and the various orders issued give us a general idea of the problems related to furloughs, we can get a different viewpoint by looking closer at the different Divisions, Brigades, and individuals who made up the army. The individual soldiers’ correspondence can also give us a more personal take on the furlough story. This paper will be far from comprehensive. It will just cover the furloughs that turn up in the surviving documentation. To make it easier to follow I have grouped the numbers and correspondence regarding furloughs by divisions and brigades.
Situated one block from where independence was declared, the structure was home to two presidents as the building served as the third residence of United States presidents. Built in 1767 by Mary Masters, the home was familiar with tenants of great importance. During the American Revolutionary War, British general Sir William Howe during the British occupation of the city. Months later Benedict Arnold, then a general in the Continental Army, moved in as he served as the military governor of Philadelphia.
After the war and a disastrous house fire, Robert Morris, the great financier, purchased the property and rehabilitated the structure. When the United States capital moved to Philadelphia, Morris offered the residence to President George Washington, and the Morris family moved next door to another property. Washington insisted that Morris receive rent for the use of one of his dwellings.
Months later, in November 1790, more people arrived to inhabit the house. Though unlike those previously mentioned, these souls did not come willingly. Washington brought eight enslaved African Americans from Mount Vernon to serve the needs of the first family, their guests, and maintain the house. One of the enslaved, Ona Judge, took the opportunity of being in a northern state to abscond from the Washingtons, never to be caught and returned. To avoid the Pennsylvania law, the Gradual Abolition of Slavery Act of 1780, which read that any enslaved person residing within the state boundaries for six months or longer owned by a non-resident would gain their freedom. Washington rotated the enslaved back to Mount Vernon in Virginia.
Besides Ona, who left the President’s House in May 1796 to gain her freedom and made her way to Portsmouth, New Hampshire. She did correspond with George and promised to return to the Washingtons’ under the condition that she would be freed upon their deaths. Belonging to Martha Washington, though, George did not have the legal right to agree to that promise. Judge created a life in New Hampshire, marrying and having three children before she passed away on February 25, 1848.
After Washington’s two-terms as president expired, John Adams, the second president of the United States, moved into the residence. On November 1, 1800, near the end of his four years, Adams relocated to the yet-unfinished White House in the new capital of the United States at Washington, D.C.
A century and a half later, the house’s remaining walls were accidentally demolished. Through the advocacy of historians and African American remembrance groups, the site was commemorated, with some of the foundation displayed under plexiglass covering. Information panels discussed those enslaved who served the house. A ghost structure showed the outline of the original structure, and the entire area was administered by the National Park Service.
The site became the center of attention again in January 2026 with the removal of those panels discussing the African American and enslaved experiences in the house that served presidents and hosted dignitaries. Their stories, though, remain as part of the fabric of the complete history of the United States. Very much including the role slavery and the enslaved played in the early American republic.

As this blog post publishes, the plight of the panels, the history of African-Americans in general, and the enslaved at the President’s House remain a topic of conversation and controversy. Continue to check the National Park Service website (click here) or other history-focused webpages for updates. Emerging Revolutionary War encourages dialogue and discussion on this topic.
In December 1775, Henry Knox wrote to General George Washington, “I hope in 16 or 17 days to be able to present your Excellency a noble train of artillery”. However, the train of artillery would not arrive until the end of January 1776. Still an impressive feat, as Knox with his team moved 60 tons (119,000 pounds) of artillery over 300 miles from upstate New York to the environs of Boston in 70 days in the midst of winter.
This impressive feat enabled Washington to evict the British from Boston, winning the siege and giving the fledgling rebellion a victory to build momentum from.
To discuss this amazing feat and part of American military history, Emerging Revolutionary War welcomes Dr. Phillip Hamilton, a professor of history at Christopher Newport University. A historian of the American Revolutionary and Early Republican periods, he has edited and written “The Revolutionary War Lives and Letters of Lucy and Henry Knox.”
Although the program is pre-recorded, Emerging Revolutionary War hopes you still tune in on Sunday, February 22 at 7 p.m. EDT. We promise the revelry will be enlightening. If you have any questions, please drop them in the chat during the program, and we will ensure Dr. Hamilton receives them.
