A national mystery
The Virginia Historical Society inherited a national mystery in 1981. That’s when it obtained the deButts-Ely family papers. The collection contains Robert E. Lee correspondence, and among it, a surprising letter from the Siege of Veracruz. In that letter, Robert E. Lee praised an unknown hero. But no one suspected that man was an assassin – the perpetrator in a record-breaking German cold case.
Lee at the Siege of Veracruz
General Winfield Scott masterminded the siege in March 1847 as the opening gambit to his campaign in the Mexican-American War. While General Zachary Taylor remained in northern Mexico, far from the capital, Scott planned an amphibious landing near Veracruz. He wanted to capture the Mexican port city and then march inland, following Cortez’s route from centuries before, to sack Mexico City.
The Siege of Veracruz was Robert E. Lee’s first battle. He directed the fire at an onshore naval battery. A German company from Pennsylvania’s first regiment was assigned to defending it. Eight Americans died at the battery before the U.S. won the siege, and one of those deaths made a profound impression on Lee. On April 11, he put his feelings on paper in a letter to his son Custis:
Robert E. Lee’s mystery letter
There was one poor fellow that behaved nobly. His thigh was broke by a cannon ball & he was laid in a trench at the rear of the battery for security, the balls & shells were flying so thick that he could not be borne away. A bush was stuck over him to keep the sun out of his eyes & all that we could give him was occasionally a cup of bad warm water. The men at the guns were hot & thirsty & drank up the water as fast as it could be brought. It was at some distance & the balls swept over the field & at such a furious rate that the officers would not let the men go for water except when they could not do without it. There the poor fellow lay till evening; when they got a litter & was bearing him off, when a shell fell & burst & a fragment killed him. He laid the whole day with the balls & bombs flying over him without uttering a complaint. His sufferings must have been very great, for the battery kept up a constant & brisk firing & the concussion from the 32 [pounders] & Paixhan guns shook the whole ground & must have pained him terribly. I doubt whether all Mexico is worth to us the life of that man.*
This unknown hero has been a discussion point in the literature. Why would Robert E. Lee balance American military objectives against the life of one man and find them lacking?
But no one, until now, has asked who that man was.

The unknown hero turns out to be a long-sought criminal
A careful comparison of the American casualty list against descriptions of the deaths at the naval battery in primary sources such as logbooks, letters, and a newspaper account from an embedded journalist all point to a German volunteer in the 1st Pennsylvania.
Robert E. Lee couldn’t have known the man’s background. It would have shocked him. The man was the assassin in a record-breaking German cold case – 19th-century Germany’s coldest case ever solved and its only murder ever solved in the USA.
For the first time, Death of an Assassin: The True Story of the German Murderer Who Died Defending Robert E. Lee (Kent State University Press, September 1, 2017) brings these two stories together. It offers American history packaged in international true crime wrapping. You can order the book here on Amazon.
Next week we’ll look at the German case and the letter from America that provided the crucial clue.

There’s only one thing more disconcerting that waking up and hearing strange noises in the night. Waking up and finding a stranger in your bed is worse. Even if it’s only a small child.
One of my favorite anecdotes of any Civil War general deals precisely with that situation. Like many other Civil War generals, this one got his first taste of battle in the Mexican-American War. That war, fought between 1846 and 1848, was like a training ground for many of the West Point graduates. For a brief period of time, they all fought side by side, only to fight against each other thirteen years later.
It was in August 1846 when it happened. He was on his way to the war, travelling aboard a steamer. The passengers consisted of 66 mules, quartered in the “Ladies Saloon,” a young soldier’s wife journeying to the front to find her husband, her little daughter, and my general, who at that point was a captain. He and the soldier’s wife had neighboring cabins in a section of the boat labeled, in gold letters, “Ladies Private Apartments.” The sole three human passengers reached their cabins by passing under a sign “Gentlemen Not Admitted.” That the future general was allowed to sleep there was probably an exception to give more room to the mules.

One night, the little girl apparently used the head and wandered back to the wrong cabin.
The future general wrote about it in a letter to his family the following day. “I was dreaming of you all last night & thought [our] daughter was in the bed with me & I was wondering how she should be so small when lo & behold when I awoke in the morning and found it was little Agnes. But I did not see that precious Mildred [one of his daughters].”
There’s no additional information about little Agnes and her mother; they remain unidentified and lost to history. But I’ve often wondered if Agnes, who was probably a teenager during the Civil War, ever remembered the incident and realized she had spent half a night in the arms of the now-famous general.
The general was Robert E. Lee, but it could have also been Ulysses S. Grant, Nathan Bedford Forrest, or George Gordon Meade for all it matters. The point is that none of those men were made of wax or marble; they were flesh and blood, like us. When they were at home, their children slept in their beds, and at least once, in the morning, one of them returned a lost, sleeping girl to her mother.

The Mississippi as the key to commerce
Even if the Civil War never happened, and even if Robert E. Lee never became president of Washington and Lee University, we would still probably know him today. He changed American history not only as a general and university administrator, but as an engineer. His most celebrated engineering feat? He made the Mississippi River navigable.
Let’s put that feat into perspective.
If you were a Midwest farmer in the 1830s, you’d need to find people to buy your harvest. Who would that be? Certainly not the folks from the next farm over. Before the era of the railroad, canals and inland waterways were the main types of transportation for transferring produce to the places where people needed them the most: the cities. As farmers moved further west, the Mississippi played an increasingly significant role. As Michael Korda wrote, “The great river that Indians called the ‘Father of the Waters’ was then America’s most important path of trade and communication, linking the grain of the Northwest and the cotton of the upper Mississippi with the thriving port of New Orleans…. It is hard to exaggerate the importance of these problems in the age before decent roads or railways existed in what is now the Midwest – goods in bulk moved by river or did not move at all.”
St. Louis was the major harbor for the Midwest. But that suddenly changed in the 1830s. Changing currents began to deposit silt in the St. Louis harbor, choking it and blocking shipping.
Robert E. Lee tames the Mississippi
The army sent Lee to St. Louis in 1837 to solve the problems. Lee had been working with the Army Corps of Engineers since graduating second in his class at West Point in 1829.
Lee’s genius was his ability to work with the river, not against it. Better than digging out a harbor is go to upstream and figure out how to lay new switches and alter the current. Lee figured out a way to let the water do the hard work. Directly upstream, he constructed two dykes off the points of the mile-long Bloody Island, blocking the current on the Illinois side and diverting it to St. Louis. By the end of the construction season, the channel to the harbor had already deepened by seven feet, allowing boats to enter again.
As Michael Korda notes, this engineering feat would have earned Robert E. Lee fame and the gratitude of the Midwest even if it weren’t for his military achievements. He opened the Mississippi to hundreds of steamboats and made the Midwest the granary of North America. That is a fitting tribute for today. January 19 is Robert E. Lee’s birthday.
What do you think the country’s greatest engineering feat was? I’ll vote for putting men on the moon.
