Joseph Champlin's Military Service During the Revolutionary War

Overview

Joseph Champlin served five separate tours of duty during the American Revolutionary War, spanning from 1775 to 1780. His service included both militia companies and the Continental Army, during critical periods of Rhode Island's involvement in the conflict.


First Enlistment: 1775

Unit: Captain Samuel Segar's Company (Rhode Island Militia)
Duration: 1 month
Period: 1775 (likely summer/fall, possibly listed as 1774 in pension records)

Historical Context

In April 1775, after the Battles of Lexington and Concord, Rhode Island responded immediately. The General Assembly voted to raise an "Army of Observation" of 1,500 men to "repel any insult or violence" and join forces with other colonies if necessary. This was part of Rhode Island's initial mobilization.

Unit Activities

Captain Segar's company would have been part of the initial Rhode Island militia mobilization. During 1775, Rhode Island militia units were:

  • Training and organizing along military lines

  • Responding to threats from British naval vessels, particularly Captain James Wallace's HMS Rose, which terrorized Narragansett Bay

  • Guarding coastal areas and strategic points

  • Preparing defenses around Providence and other key locations

  • Some units marched to support the siege of Boston

The first year of war saw Rhode Island militia primarily engaged in defensive preparations and responding to British naval raids along the coast.


Second Enlistment: 1776

Unit: Captain Samuel Potter's Militia Company (2nd Kings County Regiment)
Duration: 2 months
Period: 1776

Historical Context

1776 was a critical year when the British threat to Rhode Island intensified. In December 1776, the British would occupy Newport, but throughout the year, Rhode Island forces were preparing for this eventuality.

Unit Activities

Captain Samuel Potter commanded the 1st South Kingstown Company in the 2nd Kings County Regiment. During 1776, this unit would have been involved in:

  • Coastal defense and guard duties in Washington County (Kings County)

  • Responding to British naval raids and threats

  • Protecting supplies and strategic locations

  • Drilling and training as tensions increased

Rhode Island was particularly vulnerable due to its 400+ miles of coastline, and militia companies like Potter's were essential for local defense.


Third Enlistment: 1777

Unit: Captain Samuel Potter's Company
Duration: 5 months
Period: 1777

Historical Context

This was Joseph's longest militia service. By this time, the British had occupied Newport (December 1776) and controlled Aquidneck Island. The state was essentially in a state of siege, with British forces holding the most important port.

Unit Activities

Captain Potter's company had documented activities in 1777:

November 6, 1777 - Capture of HMS Syren: One of the most significant actions involving Potter's company occurred when the British frigate HMS Syren (28 guns) ran aground near Whale Rock on the Narragansett shoreline during rough weather. Potter's company, along with other militia units, brought up three artillery pieces and fired accurate shots at the stranded vessel. The British captain surrendered, and the Americans captured 136 British sailors and marines—a major coup that provided valuable prisoners for exchange.

Throughout 1777, Potter's unit was likely involved in:

  • Coastal patrol and surveillance of British positions

  • Guard duty at strategic points along the shore

  • Responding to British foraging parties and raids

  • Protecting livestock and supplies from British seizure

  • Supporting Continental Army operations when possible

This was a period of constant vigilance, as the British occupied Newport and made regular raids on the mainland to seize supplies.


Fourth Enlistment: 1778

Unit: Captain Timothy Locke's Company, Colonel Charles Dyer's Regiment
Commander: General John Sullivan
Duration: 1 month
Period: August 1778

The Battle of Rhode Island Campaign

This was Joseph's most significant military action. In August 1778, American forces under General John Sullivan, supported by a French fleet under Admiral d'Estaing, launched a major operation to retake Newport from British occupation.

Campaign Timeline

August 9, 1778 - Howland's Ferry Crossing: Joseph's unit was part of approximately 11,000 Continental and militia troops who crossed from Tiverton to Aquidneck Island at Howland's Ferry (also called Howland Ferry Bridge in the pension records). This was the main American landing point for the invasion. The crossing was unopposed, as the British under General Robert Pigot had withdrawn to fortified positions around Newport.

August 9-28, 1778 - Siege Operations: For nearly three weeks, American forces besieged the British garrison in Newport. Sullivan's forces dug in on Honeyman's Hill in Middletown. However, the operation was hampered when:

  • A storm on August 10-11 damaged both the French and British fleets

  • Admiral d'Estaing sailed to Boston for repairs, taking the French troops with him

  • Thousands of militia deserted when the French left

  • British reinforcements were reported to be on their way from New York

August 29, 1778 - Battle of Rhode Island (Battle of Quaker Hill): When Sullivan decided to withdraw from the island on August 28, the British garrison sortied from Newport to attack the retreating Americans. The fighting on August 29 was fierce:

  • American forces established defensive positions across the northern part of Aquidneck Island

  • The defensive line stretched from Turkey Hill on the west to Quaker Hill on the east

  • British and Hessian forces launched repeated assaults trying to break through

  • The famous 1st Rhode Island Regiment (the "Black Regiment" of African American soldiers under Colonel Christopher Greene) distinguished itself by repulsing three Hessian charges

  • The battle lasted throughout the day with heavy casualties on both sides

  • American casualties: approximately 30 killed, 173 wounded, 44 missing

  • British/Hessian casualties: approximately 38 killed, 210 wounded, 12 missing

Howland's Ferry in the Battle: The ferry crossing point was critical during the retreat. Sullivan had to maintain defensive positions to protect the withdrawal route back across Howland's Ferry to the mainland. The successful defense allowed the American army to withdraw "in perfect order and safety, not leaving behind the smallest article of provision, camp equipage, or military stores."

August 30-31, 1778 - Successful Withdrawal: By midnight on August 30, the last Continental troops were safely removed from Aquidneck Island. The operation was considered a tactical success despite failing to retake Newport, as Sullivan's army preserved itself intact and inflicted heavy casualties on the British.

Joseph's Role

As a private in Captain Timothy Locke's company, Joseph would have:

  • Crossed at Howland's Ferry on August 9

  • Participated in the siege operations for three weeks

  • Been in the defensive line during the Battle of Rhode Island on August 29

  • Helped cover the withdrawal back across Howland's Ferry

This was the largest battle of the Revolutionary War fought in New England, and it was the first major Franco-American combined operation of the war.


Fifth Enlistment: 1780

Unit: Captain Daniel Dexter's Company, Colonel Christopher Greene's Continental Regiment
Duration: 6 months
Period: 1780

Historical Context

This was Joseph's transition from militia to Continental Army service—his longest and most demanding enlistment. By 1780, the war had been going on for five years, and the Continental Army was struggling with manpower shortages, lack of pay, and supply problems.

Colonel Christopher Greene's Regiment (1st Rhode Island Regiment)

This was one of the most remarkable units in the Continental Army. Originally formed in 1777, it was reorganized in early 1778 to include enslaved and free African Americans who were promised freedom in exchange for service. By 1780, it was an integrated unit with both Black and white soldiers.

Key Facts about the Regiment:

  • Colonel Christopher Greene commanded until his death in May 1781

  • The regiment had distinguished itself at the Battle of Red Bank (Fort Mercer) in October 1777

  • It fought with great distinction at the Battle of Rhode Island in August 1778

  • It was considered one of the most disciplined and effective units in the Continental Army

  • Lieutenant Colonel Jeremiah Olney was second-in-command

  • Major Samuel Ward (who had commanded at Red Bank when Greene was wounded) was also a key officer

1780 Service Activities

During Joseph's six months of Continental Army service in 1780, the regiment was likely engaged in:

Garrison and Guard Duty: After the British evacuated Newport in October 1779, Rhode Island Continental forces were deployed in defensive positions:

  • Manning redoubts and fortifications along the Rhode Island coast

  • Guard duty at strategic locations like East Greenwich, Quidnessett Neck, and North Kingstown

  • Maintaining disciplined training and readiness

  • Protecting against British raids from New York

Life as a Continental Soldier: Unlike militia service, Continental Army soldiers:

  • Were subject to strict military discipline and regular drill

  • Followed Baron von Steuben's training methods (the regiment trained at Valley Forge in 1777-78)

  • Received (when available) standard Continental Army uniforms and equipment

  • Were expected to maintain military standards of conduct and appearance

  • Lived in military camps under camp regulations

  • Performed regular guard duty, fatigue duty, and training exercises

Challenges of 1780: By 1780, the Continental Army faced severe challenges:

  • Chronic shortage of pay (some soldiers hadn't been paid in months)

  • Limited supplies of food, clothing, and ammunition

  • War weariness after five years of fighting

  • Desertions were a constant problem

  • The main theater of war had shifted to the South

Despite these hardships, Greene's regiment maintained its reputation for discipline and effectiveness. The soldiers knew they were part of an elite unit that had proven itself in battle.

Daily Life: Joseph would have experienced:

  • Reveille at dawn

  • Morning roll call and inspection

  • Drill and training exercises

  • Guard mount ceremonies

  • Fatigue duties (building/repairing fortifications, cutting wood, etc.)

  • Guard duty rotations (typically 24-hour shifts)

  • Evening roll call

  • Tattoo (lights out signal)

The six months would have tested Joseph's endurance and commitment, but it also meant he was part of the professional Continental Army—the force that would ultimately win American independence.


Summary of Joseph's Service

Total Time Served: Approximately 15 months over five separate enlistments (1775-1780)

Types of Service:

  • Militia service: 8 months (1775-1778)

  • Continental Army service: 6 months (1780)

  • State service: 1 month (1778, Battle of Rhode Island)

Combat Experience:

  • Captured British frigate HMS Syren (November 1777)

  • Battle of Rhode Island/Howland's Ferry (August 1778) - largest battle in New England during the war

  • Various skirmishes and coastal defense actions

Units Served:

  • Three different Rhode Island militia companies

  • One Continental Army regiment (one of the most distinguished in the army)

Notable Aspects:

  • Served under both militia and Continental command structures

  • Experienced both defensive operations and major offensive campaigns

  • Survived shipwreck (date uncertain, possibly during one of these enlistments)

  • Witnessed the first major Franco-American military cooperation

  • Served in an integrated Continental regiment alongside African American soldiers

  • Fought at a critical defensive battle that preserved an American army

Joseph's service record shows a man who answered his country's call repeatedly over five years, serving in both local defense and the Continental line. His experience at the Battle of Rhode Island placed him at one of the most significant engagements of the war, and his Continental service in Greene's regiment connected him to one of the army's most elite and historically important units.

The variety of his service—from one-month militia stints responding to local emergencies to six months of hard Continental service—reflects the typical experience of many Revolutionary War soldiers, who moved between militia and Continental service as needed. His willingness to serve five separate times demonstrates uncommon dedication to the Revolutionary cause.
