Followers and supporters of William Walker's filibustering in Nicaragua

This is a list of participants in the Walker affair, an occupation of Nicaragua by American mercenary William Walker and his followers and supporters. It includes those who joined him in Nicaragua and those who supported the campaign from the United States.

William Walker

William Walker (May 8, 1824 – September 12, 1860) was an American physician, lawyer, journalist, and mercenary. After settling in California and motivated by an earlier filibustering project of Gaston de Raousset-Boulbon, Walker attempted in 1853–54 to take Baja California and Sonora, Mexico. He declared those territories to be an independent Republic of Sonora, but he was soon driven back to California by the Mexican forces. Walker then went to Nicaragua in 1855 as leader of a mercenary army employed by the Nicaraguan Democratic Party in its civil war against the Legitimists. He took control of the Nicaraguan government and in July 1856 set himself up as the country's president.

Walker's regime was recognized as the legitimate government of Nicaragua by US president Franklin Pierce and it initially enjoyed the support of some important sectors within Nicaraguan society. However, Walker antagonized the powerful Wall Street tycoon Cornelius Vanderbilt by expropriating Vanderbilt's Accessory Transit Company, which operated one of the main routes for the transport of passengers going from New York City to San Francisco. The British Empire saw Walker as a threat to its interests in the possible construction of a Nicaragua Canal. As ruler of Nicaragua, Walker re-legalized slavery, which had been abolished in 1824, albeit this measure was never enforced, and threatened the independence of neighboring Central American republics. A military coalition led by Costa Rica defeated Walker and forced him to resign the presidency of Nicaragua on May 1, 1857.

Walker then tried to re-launch his filibustering project and in 1860 he published a book, The War in Nicaragua, which cast his efforts to conquer Central America as tied to the geographical expansion of slavery. In that way, Walker sought to gain renewed support from pro-slavery forces in the Southern United States on the eve of the American Civil War. That same year Walker returned to Central America but was arrested by the Royal Navy, who handed him over to the Honduran government which executed him.

George Dionysius Tillman

George Dionysius Tillman was a lawyer, politician, and Confederate veteran. On July 21, 1856, Tillman shot and killed J. Henry Christian, a mechanic, at the Planters’ Hotel in Edgefield, South Carolina, during a dispute over a card game. Rather than face charges, Tillman fled the state and joined William Walker’s filibuster expedition to conquer Nicaragua. Upon his return to Edgefield, Tillman surrendered, was convicted of manslaughter, and served a two-year sentence in the county jail, continuing to practice law from his cell.

Despite this early controversy, Tillman went on to have a notable political career. He served in the South Carolina House of Representatives from 1854 to 1855 and again in 1864. During the Civil War, he enlisted in South Carolina military units, serving until 1865. Post-war, Tillman participated in the 1865 state constitutional convention and served in the South Carolina Senate later that year. He was elected as a Democrat to the U.S. House of Representatives, serving from 1879 to 1881, though he briefly lost his seat to Robert Smalls after a contested election. Re-elected in 1882, he served four additional terms from 1883 to 1893, chairing the Committee on Patents during the Fifty-Second Congress.

Tillman remained active in state politics, attending the 1895 constitutional convention and running unsuccessfully for Governor in 1898. He and his brother were prominent figures in South Carolina politics.

Heiss passed away in 1865.  His son served in the confederate army.

Wiley Marshall

Wiley Marshall was a twin. His twin's name was Green Marshall. Both brothers decided they were going to join William Walker in Nicaragua in the summer of 1856 but Green never made it. Wiley died in a battle in Nicaragua and Green died in California on the same day. Wiley commanded the attack on the San Jacinto ranch in September 1856. Nicaraguans defeated the filibusters in that famous battle (the Battle of San Jacinto) and today have a national holiday to celebrate their victory over Wiley and his men.

James Caleb Smith

James Caleb Smith was born on June 24, 1824, in Virginia, to Governor William “Billy” Smith and Elizabeth Hansbrough Bell. Governor Smith would become a Confederate general during the Civil War. An attorney, James Caleb Smith moved to California in 1850, accompanying his father, and quickly established himself as a prominent figure in the state. He served as a judge on the San Francisco Supreme Court and was also elected to the California Assembly, becoming a leader within the Democratic Party in the region. Smith became widely known for challenging Senator David C. Broderick to a duel in 1852, after Broderick made disparaging remarks about his father. The duel, held near Oakland Point and witnessed by thousands, resulted in no serious injuries, though Smith’s bullet famously struck and damaged Broderick’s watch, an incident that gained much public attention. It was in California that Smith most likely met Walker and other filibusters.  In Nicaragua Smith became involved in a land company. He contracted a fever and passed away in Nicaragua on May 2, 1856, at the age of 31. He was buried in Richmond, Virginia.

Prior to his death, Martin spent time in Nicaragua as a follower of William walker as a filibuster. This time was somewhat brief due to his untimely death.

Daniel K. Bailey

Daniel K. Bailey was born on January 27, 1838, in Groveland, Livingston County, New York. He was elected by his fellow filibusters to serve as a lieutenant of the first battalion in Walker’s army.

Frank William Stewart joined William Walker's army in February 1857. On March 7, he arrived in Nicaragua as part of the last company to come from California. Stewart was appointed captain of the Red Star Guard and became known as Captain Stewart. Even though he was a captain, Stewart later spoke out against the campaign, trying to share what he believed really happened in Nicaragua and clear up false ideas people had in the U.S.  Stewart recorded detailed recollections of the battle scenes and his personal interactions with William Walker, providing valuable insight into the campaign.

James Carson Jamison

James Carson Jamison was a soldier who served under William Walker, participating in his military campaigns in Nicaragua. He was born on September 30, 1830, in a pioneer home that was located about two and a half miles southeast of Paynesville in Pike County, Missouri. His father, John Carson Jamison, had migrated to Missouri from North Carolina during the early days of EuroAmerican settlement. In James' early years he worked as a miner in Georgetown, El Dorado County, in California, while waiting to join William Walker in Nicaragua. He received forty-four votes for the position of first lieutenant in Nicaragua from the others who were with him on the Sierra Nevada ship on their way to filibuster. He was later appointed by Walker to the company D of the first infantry.  Once he was back from Nicaragua he fought on the side of the Confederacy during the Civil War. He passed away on November 19, 1916, in Guthrie, Oklahoma, and was laid to rest in Clarksville.

He also made an unsuccessful bid for Congress as a member of the Whig Party. Kewen was a Mason. On November 26, Kewen, who had just turned 54, died at his old mill residence. The 1880 federal census mortality listing, recorded the cause of death as "Paralysis & Bronchial Consumption," attributed to strokes and tuberculosis.

Alexander Wake Holeman

Alexander Wake Holeman was born on February 20, 1827, in Frankfort, Kentucky, and died on October 19, 1887, in Louisville, Kentucky. Holeman was known as a professional filibuster and a soldier of fortune. He served in the Mexican-American War and was captured by the Mexican army near La Encarnación, Mexico, on January 21, 1847. He famously took two chances in a death lottery—one for himself and one for a friend he deemed less capable of facing the risk—before escaping captivity in July 1847.  He then served in Colonel Humphrey Marshall’s Regiment of Kentucky Riflemen, with whom he traveled to Cuba in 1851 to participate in the Lopez Rebellion and the Battle of Cardenas under General George Pickett. In 1855–56, he joined Walker in Nicaragua, and later commanded a Kentucky cavalry regiment on the Union side during the U.S. Civil War.

After the Civil War, he returned to Kentucky where he drew a pension for his participation in the Mexican-American War.

Alexander Parker Crittenden

Alexander Parker Crittenden was a follower and avid supporter of William Walker and his invasion of Nicaragua. In the 1850s Crittenden was a recruiter for the expedition while he simultaneously worked in California as a lawyer. Because of his status and wealth, Crittenden was a strong financial supporter of William Walker's invasion of Nicaragua. Although there is no record of his children fighting for Walker, Crittenden had many family members travel with and support his crusade. Alexander P. Crittenden did not die while fighting in Nicaragua for Walker; he was shot and killed by Laura Fair in front of his family on the docks of San Francisco in 1870. Fair, in a moment of temporary insanity—according to the courts—had shot Crittenden because during their seven-year affair he had led her to believe first that he was a widower and then that he would leave his wife, Clara, for her. The murder sparked a trial and a subsequent retrial that drew considerable public attention.

Volney R. Bristol

Volney R. Bristol was from Connecticut. It appears that he deserted from Walker's army to Costa Rica where he was forced to participate as an assistant engineer and then sued for damages. He was born on December 22, 1829, never married, and died in August 1887. He became a sergeant in the Connecticut Infantry Company I and was honorably discharged from the Infantry in 1863.

John Tabor

John Tabor was the publishing director of the El Nicaragüense newspaper in 1854. Tabor accompanied William Walker along with six of the original "immortals" aboard the steamship Fashion headed to Greytown, Nicaragua. Tabor often got into confrontations regarding his right to publish his paper in Central America. John Tabor, along with Owen Duffy, opened a law firm where they exclusively focused on claims that were made targeting the government. Tabor was influential during this time, given his role with El Nicaragüense.

Collier Clarence Hornsby

Collier Clarence Hornsby was born in Columbia, Mississippi. He was in the US Army before joining William Walker. After the military, Hornsby took part in the Nicaragua expedition with Walker in 1855. Hornsby only agreed to join Walker in taking over Nicaragua if he received the title as captain. By joining Walker early on, Hornsby is considered one of the "immortals." He married, had two children, and travelled with them. While traveling back to Nicaragua from New York, he used the name Collier Clarence Hornsby in order to not get caught by the County Prosecutor in New York. His real name was Charles Hornsby.

Martin P. Avery

Martin P. Avery was an American brigadier general and colonel born in New York in 1836. Avery was the adjutant of President Haye's regiment. He was a member of the Masonic lodge in Kansas.

Seven months later, on October 24, 1856, Walker promoted him to first lieutenant within the same battalion. He participated in the burning of the Nicaraguan colonial city of Granada. According to William Walker's memoirs, Sumpter had "unflinching courage and [a] jovial spirit". Back in the U.S. in 1862, Sumpter fought on the side of the Confederacy alongside former filibusters at the Battle of Roanoke Island in North Carolina. During the battle, he led Captain Lewis' Company, where he was wounded during the fighting.

Birkett D. Fry

Birkett Davenport Fry was born in 1822 in West Virginia. Attending two different military schools, Fry originally joined the Virginia Military Institute in 1840, but he resigned nearly a year later. He then enrolled at West Point Military School, where he also had to leave before graduating, dropping out due to his academic deficiency in math. Fry accompanied Walker on his journey to Nicaragua, originally serving as a colonel in Walker's army. While in Nicaragua, Fry eventually became a general, before returning home in 1859.

Lipscomb Norvell Walker

Younger brother of William Walker, Lipscomb Norvell Walker, fought as a volunteer from Tennessee in the Mexican American war. Lipscomb ended the war as a captain after moving up the ranks from second lieutenant. Lipscomb joined William in the conquest of Nicaragua but managed to disappoint with his embarrassing behavior, talking and drinking a lot. He eventually caught a fever during the conquest of the San Juan river and died shortly after near Havana, Cuba.

John David Walker

John David Walker was born into a family of enslavers in Georgia. He enlisted as a soldier and fought in the Mexican-American War at 21 years old, until he injured his legs on August 20, 1847, at the Battle of Churubusco. He then briefly went to Nicaragua with William Walker to filibuster. When he returned, he enlisted in the Confederate army in 1861, becoming major of the First Regiment Georgia Regulars on June 19, 1861, until February 6, 1862, where he was promoted to lieutenant-colonel. At the Second Battle of Manassas, he was shot in the leg, but refused amputation, dying of a gangrene infection on October 3, 1862, at the age of 37. It is unknown whether John David Walker had a wife or children, but he did have a brother who was a famous general in the Confederate army named William H T Walker who died only two years later.  

David Deadrick

David Deadrick was a young miner. Deadrick was a lower class citizen who worked in gold mines to make money. Due to bad fortune in the mines, in 1855 he would join William Walker in his exploration to explore Nicaragua. While exploring Nicaragua he would write a two part memoir under the name of Samuel Absalom. The title to his memoir, The Experience of Samuel Absalom, would contain the journey to Nicaragua and the relationship between American explorers and the Nicaraguan people.

Alexander C. Lawrence

Alexander C. Lawrence was an attorney. He owned a saloon in New York City from 1850 to 1857 where filibusters would hang out. The establishment was called the St. Charles' Saloon and it was located at the corner of Broadway and Leonard Streets. In August 1856 Lawrence was working as the General Emigrant Agent for the William Walker administration in Nicaragua. Lawrence's Emigrant office was located on Broadway Street in New York City.

Charles Sully Wheeler

Charles Sully Wheeler, born on November 6, 1839, to John Hill Wheeler and Ellen Oldmixon Sully, was present in Nicaragua during William Walker’s filibustering campaigns, likely due to his father’s prominent role as the U.S. Minister to Nicaragua. John Hill Wheeler openly supported Walker’s regime, helping to legitimize his government and aligning U.S. interests with Walker’s ambitions.

</ref> While no direct records exist of Charles Sully Wheeler's active participation in the invasion, his presence during this period suggests he may have indirectly contributed through his father’s diplomatic and logistical efforts. It is possible that Charles aided in facilitating communications or operations related to Walker’s campaign, given his proximity to key players and events. This exposure to the political and military activities in Nicaragua may have influenced his later decision to pursue a career in the U.S. Navy, reflecting a lifelong engagement with military and governmental affairs.

Harry Maury

Harry Maury fought in the Mexican American War. He then became an attorney. In 1858 William Walker hired him as Captain of the Susan ship which carried more than a hundred filibusters. Once in Nicaragua Maury joined the filibuster movement as a soldier. After his time in Nicaragua, Maury fought on the side of the Confederacy during the Civil War and was promoted to General.

Jane Cazneau

Jane Maria Eliza McManus (1807), later known as Jane Cazneau, was a prominent writer covering international relations and U.S. involvement abroad. As a pioneering woman in journalism, she became one of the earliest American journalists to report from enemy-controlled areas during the US-Mexico War. Known for promoting Manifest Destiny, she backed William Walker and his filibuster campaigns in Central America. Cazneau supported expansionist political movements and filibuster wars through her extensive contributions to newspapers, journals, and other publications. She is often called the "Mistress of Manifest Destiny." Cazneau sought out financial opportunities outside the U.S. and invested in a silver mine in Chontales, Nicaragua. She drowned at sea in 1878.

Jack Harris

Born in Connecticut in 1834, Jack Harris left his home to go to sea at 12 years old, later joining William Walker in 1856. As a member of William Walker's Nicaragua Expedition, Jack Harris served under the filibuster for a brief time before being rescued from a firing squad by Walker himself. After spending about four years with William Walker, Harris joined the San Antonio police force; he then served in the Civil War for the Confederacy under the Second Texas Cavalry. After the war, Jack Harris rejoined the police force in San Antonio during the Reconstruction period until 1872 when he opened a saloon at the corner of Soledad and West Commerce on Main Plaza. His saloon, named Jack Harris Vaudeville Theater and Saloon, became very popular, especially in the gambling world. One night in 1880, a former friend of Jack Harris was banned from the saloon after losing heavily and threatening the place. The threatening party, Ben Thompson, who was a known gunman, gambler, and saloon owner in Austin, Texas, returned to San Antonio on July 11, 1882, as the new City Marshal of Austin. A face-off occurred at the Jack Harris Vaudeville Theater and Saloon as Harris waited to confront Thompson and his threats of shutting down the saloon. An argument arose that ultimately ended with Harris's death after Thompson shot him in the Vaudeville Theater. Jack Harris was unmarried at the time of his death. He was a very influential member of his community with strong connections to the political authorities of the area, a fact heavily supported by the 47 carriages in the procession of his funeral on July 12, 1882. Ben Thompson obtained a "not guilty" verdict in the delayed trial on January 16, 1883.

Ellen Oldmixon Sully

Ellen Oldmixon Sully was born on January 16, 1816, and died in 1896. She was born in Philadelphia, Pennsylvania, to Thomas Sully and Sarah Annis. She married John Hill Wheeler on November 8, 1838, and they had two children, Charles Sully Wheeler (1839–1916) and Levi Woodbury Wheeler. Their two children had a half sibling from John Hill Wheeler's previous marriage to Mary Elizabeth Brown. Oldmixon Sully joined her husband's voyage to Nicaragua and spent three years there with her family in support of William Walker; her husband was the U.S. minister to Walker's government.

Ira Munson

Ira Munson joined William Walker in his invasion of Nicaragua in 1855. Walker named him Second Sargeant. Munson was also one of Walker's "Immortals". He was later a captain in the 126th New York Infantry Division in 1862. Munson fought in the Civil War on the side of the Union. He was taken as a prisoner of war and died from battle wounds on May 14, 1864.

Thomas Grosvenor Adkins and Mary Walker Adkins

Thomas Grosvenor Adkins, born in England 1823, was a very successful military musician who took over the National Home for Disabled Volunteer Soldiers Band. He spent many years in England working with bands, before then immigrating to the U.S. and finding himself in New Orleans. Accompanied by his wife, Mary Walker Adkins, they voyaged with William Walker down to Nicaragua to create a new state. After fighting with his group, he pondered around the coast, creating a group of musicians who played for the people around. He then caught a local sickness after quite some time and was brought back to New York for treatment.

Mary Walker Adkins (sometimes spelled Atkins) was the first wife of Thomas Grosvenor Adkins, a famous military musician born in England. She was also born in England and had a son who died in the U.S. Civil War. She accompanied her husband to Nicaragua. There, she and Mrs. Morris created the filibuster flag for William Walker's invading army. That flag resembled the Nicaraguan flag but replaced the triangle with five volcanoes in the middle with a red star.

Pierre Soulé

Pierre Soulé strongly advocated for William Walker's filibuster campaigns. He supported Walker's campaigns through persuasive speeches, political support, and by raising half a million dollars. He was able to raise money for Walker by speaking to a crowd in New Orleans where he requested funds for weapons and supplies. Soulé also worked as a lawyer working to defend Walker's efforts in Nicaragua. He visited Nicaragua to support Walker. There he was seen in private conferences with Walker. According to Walker, he played an important role in Nicaragua partly due to his ability to speak Spanish fluently. Some argue that Soulé played a role in convincing Walker to reinstate enslavement in Nicaragua and that Soulé was looking forward to growing cotton in Nicaragua.

Charles D. Bonsall

Charles D. Bonsall was born in Mississippi and died on June 2, 1856, in Granada, Nicaragua. He graduated with honors from the College of New Jersey (Princeton University) and later attended the University of Virginia Law School.

William Walker wrote in his memoirs that Titus was a traitor because of his abandonment of the Fillibuster Camp. Titus came close to sparking an international conflict between the United States and Great Britain when he was arrested in Nicaragua for allegedly threatening a British naval officer and making disparaging remarks about the queen of England.

Henry S. Ervay

Originally from New York, Henry Schley Ervay eventually established himself in Texas. During his time as mayor of Dallas from 1870 to 1872, he opted to go to jail rather than complying with the Reconstructionists’ orders. In the 1850s he joined William Walker in his invasion of Nicaragua. Approximately two hundred of Walker's followers landed at Fort Truxillo, Honduras, and one of their squads was commanded by Ervay. In a battle with Central Americans, Ervay sustained nine wounds. He survived, in spite of his injured limbs. He eventually went back to the U.S. and spent time in the city of New Orleans.
