The first 50 years of the 19th century was a tumultuous time in California’s history to say the least. Up until 1821, the region was under Spanish reign. Then Mexico gained its independence from Spain and enjoyed nearly 25 years of ruling over California before the Bear Flag Rebellion and eventual statehood.
Throughout those significant changes, Native American tribes experienced various degrees of hardships, cruelty, and tragedy.
Yet, out of this landscape of transition and dramatic changes, stepped a man who would become a prominent figure of early-19th-century California – Sem-Yeto, better known as Chief Solano.
Solano’s story is a blend of harsh history and lore that requires a bit of patience before the picture becomes clearer. While his life has reached legendary status, the details surrounding his mysterious death and burial have also added to his lore.
As we proceed, this article is not intended to dissect his life and weigh the decisions he made. Nor, debate whether he was a hero or not. Too many so-called historians have already done that.
Instead, I want this article to shine light on the California Native American experience during these harsh times, keep Native American history alive, and tackle the lore surrounding Solano’s death.
A Childhood Shaped by Upheaval and Tragedy
Accounts differ on whether Sem-Yeto was captured as a child during an 1810 military campaign by Moraga against the Suisun people or whether his family chose the mission after catastrophic losses from these Mexican excursions.
Considering the lengthy actions by the Missions towards Native American tribes of California, I believe he was captured and forcibly taken. Either way, it was in 1810 that we see him first appear in written sources.
At the time of this written account, he was believed to be 10 to 12 years old, was recorded having the name of Sina, and apparently had a father named Sulapy. Both of his parents were recorded as being gentiles (not baptized). On July 24, 1810, Sem-Yeto (Sina) was baptized and given the name of Francisco Solano.
Solano was one of many Suisun youths in the mission system. While there were a number of tragic examples of Native American hardships and cruelty at the Missions, Sem-Yeto’s time there was an anomaly. He learned some key tools to navigate the changing landscape as an adult, which included speaking Spanish and embracing Mexico’s military culture.
From Sem-Yeto to “Chief Solano”
The widely accepted translation of Sem-Yeto is “brave” or “fierce hand” in Patwin, the language of the southern Wintun peoples. However, it’s unclear how he received the name Sina when first arriving at the Mission.
As mentioned, the name “Solano” came later, when he received the baptismal name Francisco Solano; after a Spanish Franciscan saint during the era of the missions.
Mission registers and later histories place his baptism in 1810, during the Mission Dolores (San Francisco) period when Suisun survivors entered mission life after violent clashes with colonial forces.
The blend of names signals the terrain he had to navigate: Sina the gentile when arriving to the Mission, Sem-Yeto among his people, and Solano in colonial records.
Meeting Vallejo: From Auxiliary to Ally
By the 1830s, the Spanish mission period had mercifully faded; Mexico ruled Alta California, and military commander Mariano Guadalupe Vallejo oversaw the “Northern Frontier” from Sonoma.
In this time period, Sem-Yeto/Francisco Solano appears as a Native captain of the Mexican auxiliaries. He was a towering figure at 6’7”, and well adept at fighting. Captain Solano was also highly capable of communicating in multiple languages, negotiating peace and recruiting soldiers or allies.
Scholars debate when Solano and Vallejo first met, and what the circumstances surrounding this meeting were.
General Vallejo later said that they met in 1835, when the two were on the verge of a vicious battle. But instead of fighting, they saw the wisdom and mutual benefit of a treaty which led to a working alliance that lasted through the 1840s.
The alliance was forged out of necessity for both men. Vallejo needed Native American allies to stabilize and control the frontier, while Solano needed leverage for his future and the protection of his people.
One such example of this, was when Solano was vaccinated for smallpox which ravaged the area in 1837, and killed an estimated 60,000 to 70,000 Native Americans. Another example was receiving an official land grant, which we’ll discuss in more detail below.
War Maker or Peace Maker?
One area of Solano’s life that has been greatly debated is his leadership of the Native Auxiliary Forces for Vallejo. More specifically, the raids, battles, and wars that he waged against other tribes in the name of Mexico.
Later writers and historians would stress his peacemaking, and there is evidence of successful mediations and truces, but it would be naïve to romanticize this in a way that overlooks some of the brutalities that he perpetrated as a Captain.
In fact, there are some early written accounts detailing horrendous acts that Solano and his men committed against other tribes. Unfortunately, war is an ugly business. And, in some cases, evil things are done in the name of war.
So, this isn’t an either-or scenario. Solano wore both hats as he embraced both war-making and peace-making while walking the tight-rope of being a Native American leader in a politically volatile landscape.
A Rare Native Land Grant: Rancho Suisun
One fact sets Solano apart from other Native Americans of this era, he officially owned land. In 1842, Governor Juan Bautista Alvarado approved a Mexican land grant called Rancho Suisun to “Francisco Solano, Indian chief and Captain of the Suisun.”
The grant, about four square leagues, included much of present-day Fairfield and Suisun Valley. Vallejo himself issued a provisional authorization, later cited in court: he wrote that the land belonged to Solano “by natural right and actual possession,” pending formal title from the state.
In the American courts that followed, the wording was groundbreaking. It recognized a Native leader’s claim in a legal idiom the new regime could read. In other words, his land grant was legally valid in this new era.
Yet, even this landmark decision did not shield Suisun families from dispossession. In fact, it was a common theme in 19th century California, along with most of America, where tribal landowners lost their property but American landowners could benefit from the legal framework.
To further this point, The U.S. Supreme Court case United States v. Ritchie (1854) upheld the validity of the original Mexican grant. However, that only served to benefit Archibald Ritchie and other American landowners. It did not help the Suisun or Solano as he had already sold the land to Vallejo before the Bear Flag Rebellion due to outside pressures and threats.
It only got worse for Native American tribes after that, as they were constantly displaced regardless if there was a treaty or agreement made. And, if they objected, then they were butchered.
The 1840s: Bear Flag, Vallejo Captured, Solano Flees
In the 1840s, Solano’s reputation was at an all-time high among his allies and foes. Not only did he become a landowner, but he was also a highly regarded Captain. It’s this previous success and respect that probably saved Solano from the turbulent decade.
For California, the 1840s was a whirlwind with Russia’s withdrawal from Fort Ross, Alvarado’s brief revolt, the discovery of gold, the Bear Flag Rebellion and the war between Mexico and the United States.
Solano’s name pops up in various fragments of historical documentations from musters and letters to historical preservation written after he died.
The Bear Flag Rebellion was a turning point for Solano. Not only did it lead to the weakening of Mexico’s grip on California, but it also led to his friend Vallejo being captured and held at Sutter’s Fort. With his biggest ally gone, and presumed dead, Solano left the region.
There’s little documentation as to where he went. In fact, it’s as if he simply vanished into thin air. Popular theories are that Solano ended up in Oregon and Washington. Some sources even believe he went as far as Alaska.
Solano Returns After Years Away
Another major debate among scholars is when Solano returned from his self-exile. One group of historians believe he returned in 1850, while another group puts his return in 1858. Additionally, these years also indicate when they think he died, as well. His return was a precursor to his passing.
The widely accepted thesis for why he returned was because he learned that his friend Vallejo didn’t die. I don’t think either side will argue this point. The debate is over which year this took place.
Return and Death In 1858
Platon Vallejo, the General’s son and physician, is the primary source for the theory that Solano returned in 1858. He wrote the following:
“Twelve years after the Bear raid, in 1858, I was sitting with my father and mother on the porch of our new home, Lacryma Monte, at Sonoma. Handsome grounds surrounded the residence. A long driveway reached from the buiding to the road.
As we sat there, a gigantic figure of a man approached, clad in tattered clothes. Suddenly my father started and looked intently. The next moment he was tearing down the pathway and grasped the man’s hand. It was Solano, sure enough, older, but much the same.”
After visiting for a few days according to the younger Vallejo, the aging Chief left to go back to his childhood homeland of Yulyul, which is between modern day Cordelia and Rockville.
Return And Death In 1850
In other sources, Samuel Martin, who came during the Gold Rush, met Solano at Rancho Suisun in 1850. He claimed that the elder Chief was very ill and died of pneumonia after the Martin family tried to take care of him. Martin also stated that he was good friends with Solano by the time he died.
Popular Theories On Solano’s Burial Site
Solano’s life is filled with incredible tales intertwined with harsh realities. And, yet, the mystery over where his burial site is located, seems to perpetuate the Chief’s legendary footprint on California. There are a few key schools of thought where Sem-Yeto is buried.
Buried Under The Old Buckeye Tree
Perhaps, the most widely accepted theory is that Solano was buried under a buckeye tree across from the Martin home.
Mrs. Henry Martin, daughter-in-law to Samuel Martin, wrote a letter in 1932, supporting the story that Solano was buried under the old buckeye tree. According to a February 5, 1967, article in The Times Herald, Mrs. Martin made the following comments:
“The Chief was buried not far from the old buckeye tree in the burial ground of the Indians – Suisunes; my husband, Henry Martin, was shown by his father, Samuel martin, Chief Solano’s grave and was told interesting tales of their friendship.
These are undisputed facts. No one in the valley can testify to any facts of Chief Solano’s residence in any other place. It is a shame that people who know nothing about Chief Solano try to dispute these facts.”
A December 18, 1885, article in The Solano-Napa News Chronicle claims that the Chief’s grave was within 12 feet of the corner of Mr. Martin’s house and was still resting there at the time of the publication.
Additionally, author Frank Keegan supports this theory in his book Solano, The Crossroads County, an Illustrated History.
Buried in Petaluma, Ghost Of SCC
Other theories say that he is buried underneath Solano Community College or on an island in Petaluma Creek.
In particular, the Community College theory is also tied into the local lore of a tall Native American ghost reportedly haunting the campus for the last few decades.
As for the Petaluma theory, this is based on a statement allegedly told by Mr. Richard Emparan who was a grandson of General Vallejo. He said the following:
“I heard my mother, Louisa Vallejo Emparan, say many times that she had heard her father and mother say that Chief Francisco Solano of the Suisunes tribe died in Petaluma.”
The Skull of Chief Solano
One more disturbing story entered into the Solano lore by the early 20th century. This one centers on the Topley family allegedly receiving and disposing of Solano’s skull.
According to The Times Herald, Mr. William F. Topley, whose family conducted the Topley Pharmacy on Georgia Street in Vallejo, came into possession of Chief Solano’s skull. Mr. Topley would make the following comments:
“My father stated that between 1890 and 1900, Dr. Platon Vallejo came into the pharmacy and said ‘here is Chief Solano’s skull’, with no further explanation.”
Topley would go on to say how the skull was placed atop a bookcase for many years. It gathered dust and cobwebs over time, while scaring customers. So, during a housecleaning in 1925, the skull was disposed of down a well behind the pharmacy:
“The skull, along with other material, was dumped into an abandoned well at the back of the pharmacy – at No. 316 Georgia Street. This is where it is resting today.”
In his memoirs, Platon Vallejo stated the following:
“Many years after his remains were exhumed and his skull is now in the possession of Mr. Topley, a druggist of Vallejo.”
As deplorable as something like this sounds, it was par for the course when it came to grave robbing and destroying sacred Native American burials.
In fact, because of Solano’s burial being a popular mystery in the early 20th century, Native American graves were being dug up and examined for a tall skeleton. Not only was one never found, but all of those graves were unnecessarily disturbed.
The Legacy of Solano
The county, created in 1850 as California entered the Union, took its name from Chief Solano—reportedly at the behest of General Vallejo, who emboldened the legend of Solano to the new government.
Not only did Vallejo affectionately speak of his friend when urging California to name a county after Chief Solano, but he also ensured that Sem-Yeto’s story would forever be told throughout the history of this state.
In other words, Vallejo immortalized Chief Solano in a way that turned the man into a symbol and a survivor into a legend.
A 12-foot statue was built of Solano by Gordon Huff and unveiled in 1934. It was moved a few times in order to protect it from vandals. Today, that beautiful statue is the physical embodiment of Solano’s symbolism. And, all of the plaques are reminders about his life and death.
As for his burial, Paul McHugh wrote an article about Solano for The SFGate in 2002. He wrapped up the piece by saying the following: “The truth is, he’s gone back to the earth, and so is everywhere and nowhere.”
This is how I like to think of Solano. His spirt is everywhere and nowhere. He’s at peace. So, let the mystery over where he’s buried blissfully fade like the sun setting on Suisun Valley.
