Top 5 Foreign Continental Army Officers (Other Than Lafayette)

At the war’s outset, there was a dearth of proven military leadership within the thirteen colonies severely limiting the Continental Army’s ability to engage the British on equal terms. This paucity of military leadership was especially pronounced in the technical aspects of war including engineering, artillery and cavalry.

To fill the void, the Continental Congress authorized its diplomatic representatives in Europe to recruit experienced military leadership, especially those with extensive military arts and engineering capabilities.[1] Fortunately peace in Europe provided a large pool of interested, unemployed officers some of which identified with the democratic ideals of the American Revolution.

The initial targeted recruitment turned into hundreds of volunteer officers traveling to America for officer commissions, many of which had suspect backgrounds and credentials. American born Continental Army officers felt aggrieved by these Congressional appointments. Washington wrote Benjamin Franklin, “It would be prudent and just to discourage their coming over…”[2] In addition; some volunteers did not perform well. For example, Brigadier Generals Matthias A. R. de Fermoy and Prud Homme de Borre were disgraced in battle and returned to Europe[3]. Others such as Major General Thomas Conway became embroiled in a political intrigue. Conway was implicated in a plot to replace General Washington, which when not successful, led to Conway’s resignation.

However, many foreign volunteers performed superbly and provided critical military expertise. Marquis de Lafayette is the obvious choice as the “most valuable” foreign volunteer. George Washington and his contemporary general officers highly valued Lafayette’s leadership, courage and loyalty. A more interesting question is which other foreign volunteers were most valuable to the patriot cause. Many French volunteers as well as volunteer officers from Canada, Prussia, Germany and Poland provided noteworthy contributions and today are significantly less recognized.

At the time of the revolution, one’s nationality was a murky concept.  Everyone living in a colony was a British subject regardless of birth place, culture or language.  However, most people had primary allegiance to their colonial affiliation and not to a common American nationality which had yet to be created from a subset of British colonies.   Therefore I consider anyone living outside the thirteen colonies at the war’s outset to be eligible for consideration as the most valuable foreign volunteer.  Here are my views within the following military roles:

  • Inspector General/Drillmaster – Major General Baron de Friedrich W. A. Steuben
  • Infantry Commander – Brigadier General (Brevet) Moses Hazen
  • Military Engineer – Brigadier General (Brevet) Thaddeus Kosciuszko
  • Calvary – Brigadier General Tuffin Charles Armand, marquis de la Rouerie
  • Battlefield bravery – Lieutenant-Colonel Francois Louis Teissedre de Fleury[4]

To be considered for this list, the foreign officers must have earned their honors fighting in the Continental Army, not serving in the French Army in America.

Inspector General/Drillmaster – Major General Baron de Friedrich W. A. Steuben

“Major General Friedrich Wilhelm Augustus, Baron von Steuben” by Ralph Earl. Current location: Yale University Art Gallery

Baron de Friedrich W. A. “von” Steuben came to America claiming to be a titled noble and a Lieutenant General in the Prussian Army. His grandfather added the “von” to elevate the family’s prestige and the Baron title is attributed to an award of the Order of Fidelity by a German princess. While the title claim has some validity, his claims of nobility were suspect and his rank in the Prussian Army, Captain, was vastly exaggerated.[5] However dubious his credentials, Steuben possessed extensive military education that greatly exceeded the technical military knowledge of American officers.

Steuben quickly gained Washington’s confidence leading to his Congressional appointment as Inspector General. In this capacity Steuben excelled and earned his military reputation. As Inspector General he was responsible for training the Army and is best known as the drillmaster of Valley Forge. During that horrible winter of 1777-8, he led an intensive training program instructing officers and enlisted men in European fighting tactics required to engage the British army in open field battles.

The next winter Steuben authored the first United States Army military code in three parts – a drill manual, a set of official regulations governing army activities and a treatise on conduct of officers and enlisted men. This manual was widely praised by Washington and the Board of War.[6]

However, Steuben’s Continental Army service was not without controversy. Steuben desperately sought to command men in battle. Eventually, Washington relented and sent him south in 1780 to join General Nathanial Greene’s Southern Army. On his way Steuben’s orders were changed when the British under General Benedict Arnold invaded Virginia. Washington was keen on capturing Arnold while protecting Virginia from destruction. In this capacity Steuben failed. He clashed with local militia leaders, turned out to be an ineffective battlefield tactician and was eventually replaced in command by Lafayette.

However in the end, his statue in Lafayette Park across from the White House is a well-earned tribute as he led the transformation of the Continental Army into a competent fighting force, which could hold its own against the British Army on the open battlefield.

Infantry Commander – Brigadier General (Brevet) Moses Hazen

After daring battlefield service during the French and Indian War as a provincial officer, Moses Hazen joined the regular British Army. Prior to the Revolution, he retired as a lieutenant on half pay to live in Canada. Hazen, a large landowner in the Richelieu Valley just north of Vermont had a difficult decision as to which side to support and his initial loyalties were not easily discerned. He was an American by birth but tied economically to Canada and British rule.

To counter the patriot invasion, Governor Carleton authorized Hazen to raise troops for the protection of Canada. Hazen met with both sides but did not raise militia to support either side. The patriot invaders on their way to Montreal and Quebec plundered his estate and briefly detained him. British forces quickly recaptured Hazen and not trusting his loyalties, the local British commander at St. John sent him to Governor Carleton under arrest. During the patriot attack on Quebec, Hazen escaped and considerably aided the patriot forces in the remainder of the Montreal and Quebec campaign. Through these military exploits Hazen became regarded as one of the leading Canadian patriots and was sent to meet with the Continental Congress in Philadelphia.

As result of his confirmed loyalty and demonstrated military leadership, Congress commissioned him Colonel of the 2nd Canadian Regiment. This unit became known as “Hazen’s Own” and initially consisted of like-minded Canadians interested in independence from Britain but eventually soldiers were recruited from other sources. The 2nd Canadian fought at the battles of Staten Island, Brandywine and Germantown. At Brandywine, Hazen’s Regiment was part of the American right that held fast when the rest of the American front fled the battlefield.[7] During the Yorktown campaign, Hazen commanded the 2nd Brigade of Lafayette’s Light Division.

I selected Hazen as the most valuable infantry unit commander as he skillfully and reliably commanded a combat regiment throughout the eight-year war. However, he was court martialed twice; the first resulted from a clash with Benedict Arnold, the second Baron Steuben. Both times he was acquitted.

Even with these miscues and a tempestuous personality, Hazen’s military contributions were widely recognized. “Hazen’s Regiment seems to have had an exceptionally good record…”[8] He was a reliable battle commander, kept open the threat of Canadian invasion by the patriots and maintained a combat effective regiment throughout the war. Further, at war’s end, he received a brevet promotion to Brigadier General and was granted land in northern New York to reward his service and to recognize his lost Canadian estate.

Military Engineer – Brigadier General (Brevet) Thaddeus Kościuszko

For the most valuable military engineer, the conventional selection would be Major General (Brevet) Louis Lebegue Duportail,[9] the chief engineer of the Continental Army. However, I selected Thaddeus Kościuszko as he provided hands on field contributions leading to the American victory at Saratoga and to the defeat of the British in the south under General Greene.

Thaddeus Kościuszko a former Polish military officer came to America without a formal invitation. He approached Benjamin Franklin, who was impressed enough to recommend Kościuszko as a military engineer. Franklin’s recommendation was sufficient for Congress to appoint Kościuszko to the rank of Colonel on October 18, 1776. Kościuszko’s first assignment was to fortify Philadelphia. Most notably he initiated construction of Ft. Mercer at Red Bank, New Jersey.

In this capacity, Kościuszko caught Washington’s eye and due to a good relationship with General Horatio Gates, Kościuszko was appointed Engineer of the Northern Army. At Fort Ticonderoga he recommended fortifying Sugar Loaf Hill (Mt. Defiance) but was over ruled by General Philip Schuyler, which turned out to be a huge mistake as British cannons on these heights forced the hasty evacuation of Ticonderoga.[10]

After Burgoyne’s surrender, Kościuszko was appointed military engineer at West Point where he greatly strengthened its fortifications. Further he developed a now unknown innovative mechanism for hauling the large chain boom in and out of the Hudson River.

When the fighting shifted to the south, Kościuszko was sent to aid the Southern Army. He was instrumental to General Greene’s campaign strategy by securing boats for crossing the numerous Carolina rivers. Swift and safe river crossings allowed Greene to outpace the British Army contributing to the eventual patriot victory.

Kosciuszko was not the highest-ranking military engineer, but made meaningful contributions in both the northern and southern theaters. He was highly respected by patriot general officers and at war’s end he was rewarded with a brevet promotion to Brigadier General. Further during the southern campaign he became an ardent opponent of slavery. At his death he willed his fortune to assist in the eradication of slavery.[11] There is also a statue of Kościuszko in Lafayette Park by the White House.

Cavalry – Brigadier General Tuffin Charles Armand, marquis de la Rouerie

To better relate with his fellow patriot officers, the Marquis de la Rouerie dropped his aristocratic title and shortened his name to Charles Armand. In an inauspicious start, he was assigned to a ragtag group of German speaking Pennsylvanians called the Ottendorff’s Corps. Interested in cavalry and with his own money, Armand formed the 3rd Calvary Pulaski’s legion and on May 10, 1777 was appointed to the rank of Colonel by Congress. After his first battle on June 26, 1777 at Short Hills, New Jersey, Washington commended Armand for his personal courage in saving a field gun.[12]

Armand led a strong rear guard action at Brandywine allowing an orderly retreat by Washington’s forces. He also participated in battles at Whitemarsh and Monmouth. When Casimir Pulaski was killed outside of Savannah, Armand assumed command of Pulaski’s legion that was renamed Armand’s Partisan Corps. His focus shifted to daring raids and partisan operations in the New Jersey/Hudson Valley region. On November 7, 1779 Armand captured Alderman Leggett, a high-ranking loyalist in his home as he slept. He also captured Major Baremore and Captain Cruser in subsequent operations.

The only question of his battlefield leadership came during the battle of Camden in 1780. Armand contended that General Gates placed Armand’s legion in the front of the Army, an impossible position to defend as payback for a perceived earlier slight. Accounts of Armand’s performance vary with British Lt. Colonel Banastre Tarleton reported in his memoirs that Armand “played a good countenance”[13] while patriot Colonel Otho Holland Williams wrote “Some of the cavalry of Armand’s legion were wounded, retreated and threw the whole corps into disorder.”[14] Other patriot leaders were neutral.[15] After Camden, Armand traveled to France to raise money and men and was awarded the Chevalier de Saint Louis.

He returned to resume leadership of his legion and under Lafayette’s command fought at the battle of Green Spring on July 6, 1781. Most notably during the Yorktown campaign, he participated in the assault on Redoubt #10 with Colonel Alexander Hamilton.

While Casimir Pulaski is more famous, Armand contributions were more significant to the patriot victory. At the war’s end, Armand received warm congratulations from Washington for his promotion to Brigadier General and chief of cavalry.[16] He was one of the first foreign volunteers to arrive and among the last to leave. Armand proved the value of cavalry in the revolutionary war campaigns and received the following congratulations from Congress:

“…I am directed to write to you, and to express the high sense Congress are impressed with of the services you have rendered to the United States, in the course of the late war with Great Britain; and their entire approbation of the Bravery, Activity and Zeal you have so often evidenced in the Cause of America”.[17]

Battlefield Bravery – Lieutenant-Colonel Francois Louis Teissedre de Fleury

Assessing relative battlefield bravery is subjective and can be controversial. I rated Francois de Fleury first in this category as he was awarded two metals for battlefield valor and was wounded twice. To this day the United States Army Engineer Regiment awards a de Fleury medal to United States Army engineers “who exemplifies boldness, courage and commitment to a strong national defense.”[18]

De Fleury was an early volunteer from France.   Commissioned a Captain on May 22, 1777 he served in the forces defending Philadelphia from British invasion. De Fleury was wounded twice, first at Brandywine and then again in the courageous defense of Fort Mifflin. After the Philadelphia campaign, de Fleury was appointed LT Colonel of Engineers and then appointed assistant inspector general under Baron Steuben.

De Fleury returned to active an combat unit and participated in joint American French assault of Newport in August 1778. The next year, he led a battalion in the attack on a strategic British fortress on the Hudson River at Stony Point, New York. To avoid the possibility of a gunshot alerting the British the patriots attacking force used bayonets and unloaded muskets. de Fleury not only led the right wing of the three pronged attack but was the first man into the British works and also cut down the British colors.[19]

Congress formally recognized de Fleury’s valor by awarding a Congressional medal for his “zeal, military genius and gallantry.”[20] He is one of only eleven medal recipients during the revolution and the only one earned by a foreign volunteer.[21] In September 1779 he requested a leave of absence to obtain additional armament and financial support in France for his legion. Returning with General Rochambeau’s army, De Fleury received a second medal, the Chevalier de Saint Louis for distinguished service at Yorktown.

While John De Kalb and Casimir Pulaski died heroically in combat, de Fleury received the highest tribute from his contemporaries exemplified by his medal award resolution; “he has rendered essential benefit to the American cause, he has deservedly acquired the esteem of the army and gained unfading reputation for himself.”[22]

Other than Lafayette, the important contributions of foreign volunteers are often overlooked. While some of the volunteers were mere opportunists and incompetent, these five officers provide substantial evidence that many foreign volunteers deserve recognition on equal footing as native-born military leaders. They also serve as a reminder that one of the best features of American culture is to accept and leverage the most valuable abilities of the people willing to travel to our shores.

  • Interesting topic, among the other “top ten” or “top five” lists we see. I might nominate Bernardo de Galvez. Although he was not aligned with the Continental Army his work fighting in Louisiana and Florida was influential.

  • Gene – a very well researched and thoughtful list. I knew about Steuben and Kościuszko, but was less aware of Hazen, Armand, and De Fleury. Now I know. Thank you for your informative article!

  • For his actions at Stony Point, de Fleury was also awarded 500 dollars (which he gave to his men) and immediate promotion, which he declined as it would have meant leaving his regiment. When we give the Army Engineers Staff Rides at Stony Point, they love to run up to the point where de Fleury struck the British colours and reenact the moment.

  • Excellent list Gene. I’m glad to see Thaddeus Kościuszko on there. He’s one of those officers that can slip under the radar since he wasn’t as “flashy” as some of the others. His opinions, as you pointed out in fortifying Mt. Defiance, were basically ignored. I believe it took some convincing on his part for the Northern army to even settle on the strategically fortified Bemis Heights in preparing for the upcoming Battles of Saratoga.

    If I had to replace one, it would be Moses Hazen for Pulaski, or even someone like Bernard Romans. I realize Romans is another military engineer, but he was of great importance to the army, especially early on. He seemed like the only competent officer to come out of Hartford or Pittsfield during the initial raid on Fort Ti. Instead of preparing self-serving reports, as others had done after the raids’ success, he carefully completed the inventory of the artillery. Not very glamorous but a necessity for Washington’s army in Boston. He had his low points with the Hudson Highlands debacle, but he did have a strong presence in the Quebec campaign, and the maps he produced were invaluable throughout the war.

    There’s no doubt that Moses Hazen’s expertise in the Canadian region, feel for the temperament of the people, and battlefield tactical insight, were all of great assistance to the Continental army. Something that bothers me about him though is his devious and vindictive behavior around the whole episode around the seized Canadian goods he was ordered to store by Arnold. (As Arnold had prior been ordered to do in Montreal for the army) He made a mess of the situation out of spite; likely from his disagreements with Arnold in the Cedars, when his thoughts should have been on the bigger picture involving the impending attack down Lake Champlain by Sir Guy Carleton.

    Either way it’s an excellent list that never crossed my mind before.

  • I may also forward the name of Captain Tho. Machin, engineer and officer in Lamb’s Artillery regiment. He was, according to the book “Fusiliers” by Mark Urban ( a very good book in its own right) a deserter of the 23rd RWF outside of Boston and stayed in the Continental Army for the war. Would you consider him “foreign”?

    • Looking at the officers selected, it appears that the chief criteria is that the person traveled to the colonies specifically to fight for the Americans. There were many American officers who were born overseas, including Generals Charles Lee and Richard Montgomery, but they were already in America when the war broke out. I think Thomas Machin (and a handful of other British soldiers who deserted and became American officers) falls into this category – he didn’t come to America explicitly to volunteer for American service.

      This is why American-born Moses Hazen does fit into this list – he was born in America, but was living in Canada when the war broke out and returned to the rebelling colonies for the explicit purpose of volunteering for service.

  • Gene, a most interesting article on a subject not often noted as we tend not to focus on the important role played by France, Spain and foreign individuals. Kosciuszko also was probably only second to Lafayette as a foreign officer with an impressive record in the intelligence field. Under Greene in the south, he took over the intelligence networks of Col. John Laurens and managed them most effectively.

    It is worth noting that the use of “contractors” by the American Army did start with its very inception.

  • Don, I’m not suggesting that they fit in a top five list, but did any of the Swedish officers in French service rise above the mun-Dane?
