July 2, 2009: Barry Cauchon

The Lincoln conspirators are prepared for execution at the Washington Arsenal Penitentiary on July 7, 1865.
July 7, 2009 will mark the 144th anniversary of the hangings of the Lincoln conspirators at the Washington D.C. Arsenal Penitentiary. Over the past few months, I’ve had the privelege to converse, exchange ideas and share research with my now good friend John Elliott from San Antonio, Texas. John has been working hard at pulling together a history of the Arsenal Penitentiary from before, during and after the period that the trial and executions occurred.
Today, the penitentiary no longer exists except for one structure, referred to as Building 20 (or Grant Hall) which is all that remains from the west end of the structure. It was on the third floor of this part of the penitentiary that the conspirators’ trial took place.
The land that Building 20 now stands on is located at Fort Lesley McNair, a restricted military installation. Due to the events of 9/11 in 2001 and the security changes that resulted from that event, Fort McNair is no longer open to the public. However, John has gained access on two occasions (all legally I assure you) and not only photographed the site but conversed with several people involved in the current project to restore the building (inclusive of the trial room). It’s a fascinating project and I’ve really enjoyed hearing about the plans they have scheduled for the building.
Since most of us will not have an opportunity to see this historical site without military access to the Fort, let me share with you this three-part series that John has compiled starting with Part 1: The Pre-Trial Period (1831-1862). Enjoy.

THE WASHINGTON D.C. ARSENAL PENITENTIARY
A History of the Prison Where the Conspirators of the Lincoln Assassination Were Tried and Hanged
Part 1: The Pre-Trial Period (1831-1862)

On April 27th, 1865, after being examined and identified as the assassin of Abraham Lincoln, the body of John Wilkes Booth was transferred from the USS Montauk to the Washington Arsenal Penitentiary. Under orders of strict secrecy, his body was buried 10 feet deep in a storage room at the prison. The storage room was located behind an iron door just 5 to 6 feet away from the Warden’s quarters. Booth’s corpse would remain on the arsenal grounds for the next 4 years. Thus began the penitentiary’s storied history and its connection with the Lincoln assassination conspiracy.
Thirty four years earlier, the D.C. Penitentiary opened its cell doors for the first time when Thomas Williams began serving a one year prison sentence for stealing a $6.00 barrel of flour. Upon entering his prison cell, Williams was issued a Bible, two blankets and a coarse sheet. He was also given the following rules to abide:
- You shall be industrious and labor diligently in silence.
- You shall not attempt to escape.
- You shall not quarrel, converse, laugh, dance, whistle, sing, jump, nor look at nor speak to visitors.
- You shall not use tobacco.
- You shall not write or receive letters.
- You shall respect officers and be clean in person and dress.
- You shall not destroy or impair property.
The D.C. Penitentiary was built during an era of prison reformation. In the early 1800s, society no longer felt that corporal punishment would reform criminals or provide an effective deterrent to crime. Instead, religion, productive work and discipline would be the tools used to accomplish rehabilitation while providing a means to offset the cost of confinement. As a result, Congress allocated funds to construct Washington D.C.’s third prison. Unlike the other two (Old Capital Prison and Alexandria Jailhouse) which were built as temporary holding cells until one could be brought to trial, the new penitentiary would focus on rehabilitating inmates into becoming productive citizens.

One person who was committed to seeing the D.C. Penitentiary and all its reform initiatives succeed was the famous humanitarian Dorothea Dix. She donated $100.00 of her own money to the penitentiary library. This was the equivalent of about $2500.00 in today’s (2009) economy.

Charles Bulfinch, the architect of the Capital building was selected by President John Quincy Adams to design the new penitentiary. Its location was ideally suited to transport prisoners and supplies by water rather than laboring through city streets. The D.C. Penitentiary was situated just north of the main arsenal buildings on a small peninsula known as Green Leaf Point. Total funds appropriated to build the penitentiary were set at $140,000.00.
D.C. Penitentiary Plan

In “Fort Lesley McNair and the Lincoln Conspirators”, Lincoln historian Michael Kauffman provides the following description of the D.C. Penitentiary:
The original penitentiary consisted of a twenty-foot wall enclosing a three-hundred foot yard and three buildings. The largest of these buildings was a cellblock containing 160 cells. It was flanked on the southwest and southeast corners by two identical buildings which were the administrative offices and the prison hospital, respectively. These three buildings made up the entire prison until the growing number of inmates forced the expansion of facilities.
The central building measured 120 by 50 feet, and from outside it appeared to be a three-story building. But actually, the outer walls formed a shell that enclosed an inner cellblock structure. The cells themselves were arranged in four tiers, and each was divided into two ranges of twenty cells each.

Charles Bulfinch's sketch of the penitentiary.
Walkways ran lengthwise along both sides of each range and led to stairways at the east and west ends of the cellblock. Each cell measured 7′ by 3 ½′ by 7′ with solid masonry walls eighteen inches thick. Their iron doors opened alternately to the north and south to prevent the prisoners from communicating with each other.
Originally, the top tier of cells was to be used for the women inmates, but this plan was soon abandoned. Two ninety foot extensions were added to the east and west ends of the cellblock, and one half of the eastern extension became the new women’s ward. The other half became the deputy warden’s quarters.
With the completion of the new extensions, the building measured 300 feet by 50 feet, with two 25 foot sections along the south wall, 120 feet apart. The extreme ends of the building could be entered from outside the penitentiary, and all of the sections were connected by a series of hallways and iron doors.

The far west section was considered the main visitor’s entrance to the prison and this is where the warden had his office and living quarters. This section consisted of four rooms on each of its three floors. On the first floor, an iron door led to a large storeroom immediately to the east. This room was also part of the western extension and joined the main cellblock at its east wall. Directly above the storeroom was the prison chapel, and a new prison hospital was established on the third floor of this section.
Entering the cellblock’s south hallway from the storeroom, one could pass straight through to the eastern extension. Here another iron door led to the women’s cellblock. This section’s 64 cells were designed and arranged much the same as those of the men’s cellblock, but they were twice as large as the older cells.
Adjoining the women’s cellblock was the deputy warden’s quarters, a part of which was originally used for the prison laundry. This was the far eastern section of the penitentiary, and it also consisted of three floors. It differed from its western counterpart only in that it did not have four rooms on its third floor. A T-shaped hallway had been altered on this floor, which left the two northern rooms undivided. Thus, the northern half of the third floor consisted of one large room which measured about 40 feet by 27 feet.
Expansion of the prison was completed in the mid-1830s when a wash house and a shoe factory were built on the grounds to occupy the prisoner’s time.

For 31 years, the D.C. Penitentiary operated with mostly failed results. The shoe factory built to make the prison self sufficient never made a profit. According to the prison staff, inmates were seen as too lazy and incompetent to properly use the tools they were given. In addition, no continuity in the workshops could be achieved because of inmates being brought in and being released. The average prison sentence for 90 percent of the inmates was less than two years. In an effort to increase the prison population and improve the labor production, the penitentiary opened its doors to non-district prisoners in 1850. It would not be enough. The penitentiary, despite its noble efforts at prison reformation, was soon to be closed.
In 1862, citing a need for more storage space for the arsenal, Abraham Lincoln stated that the prison was “absolutely necessary” for military purposes. Lincoln ordered that the prison be turned over to the War Department and that the convicts be transferred to other prisons. Some inmates were sent to Albany, New York State Prison while others were transferred to the front lines. The Arsenal Penitentiary would never again serve as a prison until the spring of 1865.

Wasn’t John Wilkes Booth Buried Here?
Hi Shelby: Thanks for writing. You are absolutely correct. John Wilkes Booth was buried in the storeroom at the west end of the penitentiary building on April 27/28, 1865. His body stayed there until 1867 when it, along with the other conspirators’ bodies (and Henry Wirz’ body – the commandant of Andersonville Prison – who was buried there after his execution) had to all be moved due to the penitentiary being demolished. All six bodies were transferred to Warehouse 1 on the east side of the Arsenal grounds until February of 1869 when the bodies were released to their families.

I am so glad that I cam across your website. Now I just have to figure out how to navigate it, being somewhat computer-challenged.
I walk through Ft. McNair to and from work each day and have been fastinated by the history represented. My interest was first piqued by a placard that identifies Building 20 (Grant Hall) and its significance. I must say that looking at that tennis court and realizing what happened at that location was sobering, even chilling. I applaud your and Mr. Elliott’s efforts at documenting the location and events.
Hi Jon: So glad you like it. I don’t get down to Fort McNair often so I’m a tad jealous, but some of their people have been just wonderful to us.
It is funny that you mentioned the placard. It has been in front of the Building 20 for a few years and yet, unfortunately it has 2 or 3 glaring errors in it. The biggest one is that the bodies of the conspirators were returned to their families in 1867. In fact, President Andrew Johnson did not release the bodies back to their families until the winter of 1869. Along with the four hanged conspirators, the remains of John Wilkes Booth and Henry Wirz (also buried at the Arsenal Penitentiary) were also released to the families.
Hopefully one day, the placard will be changed to properly reflect real history.
Thanks again Jon. We look forward to hearing from you again soon.

I lived in the court house and we all (old guard families) knew the history and of the “ghost” of Mary Serrat. Many families children spoke of her visiting with them at night. Often I would have the light down stairs go out and say “Mary turn the light back on” of course it was fun, but also some what spooky, especially when my brother came and slept in the front livingroom that was beside the tennis court side and he said he heard hammering all night.
I believe the body of John Wilkes Booth was carried from the Anecosta River to the hospital at the prison through a tunnel that was later filled in during the depression era. Also, there are still prison cells under one of the buildings near the tennis courts.

Hi John: Thanks for your comments. The penitentiary cells no longer exist (they were destroyed when the prison was razed in 1867). However you are correct that some basement cells still exist (or used to) in other nearby buildings. We have photos of these from a few years ago but have not satisfactorily located where these were taken. We know that they are not located at Grant Hall (Building 20) but may be in the Model Arsenal (Building 21). As this is not the main focus of our research, it has fallen down the priority list for us. But if you do find out where they are/were, we’d love to know. The recent renovation at Grant Hall did uncover some areas in the basement that certainly looked like cells but in fact were coal bunkers.
The story of John Wilkes Booth’s body and it’s burial always fascinates me. Right after his autopsy on the USS Montauk moored at the Navy Yard, he was removed and taken to the penitentiary on the Eastern Branch (now as you mention, now called the Anecosta River) and buried under the floor of the storage room at the west end of the prison. He remained there until 1867, when his body, along with the bodies of the four executed conspirators and Henry Wirz (commandant of Andersonville Prison) were moved to Warehouse 1 (located just south of the penitentiary) when it was scheduled to be demolished. Have a great day and thanks again for a great comment.

Thanks, Barry. The building where I saw the cells was, at the time, the quarters of the Executive Officer of ICAF. The cellar level cells can be seen from the ground surrounding the building. They were built on an upward angle. It seemed that there was a moat in front of the cell opening to keep the prisoners away from where the doors to the cell would have been installed. However, you may be correct in suggesting that these were actually coal bunkers and not prisoner cells. Historically, that would make more sense than their being overflow prison cells..
Hey John: Thanks again. I checked with my writing partner who was there about 4 months ago. He sent me photos of the ‘bunkers’ when they were excavated and visible during the current renovation. After researching the images, he discovered very similar ones that matched the same designs of other coal bunkers. We concluded that this is what they were. We also believed that the need for cells in the basement of this particular building would seem moot considering there was a complete penitentiary attached that had cells available for both men and women. However, as mentioned earlier, the Model Arsenal probably did have cells in its basement (as per the photos that author Betty Ownsbey sent us) from about 20 years ago. We believe they may no longer exist as the condition of the cells was very poor at the time the photos were taken. Still, it makes you wonder…WHAT IF!
Have a great day John.

Just finished O’Reilly’s, “Killing Lincoln”, What are your thoughts regarding the book?
JHD
I just watched the Conspiritar about Lincoln. Do you know if we can tour the old D.C. Penitentiary/Aresnal????

Hi Emma: Thanks for your question. Regrettably there are no tours given of the site. Today, the grounds of the old Washington arsenal and the location of the former penitentiary are located within the confines of Fort McNair, a military installation. You have to clear the check point guardhouse to get in. But if you can, then there is no problem visiting and seeing what is the only part of the penitentiary left standing (it is the east part of the structure where the conspirator’s trial was held on the third floor). This building is currently called Grant Hall or Building 20. It is under renovation to restore the third floor back to its original ‘trial’ set up. I believe the furniture from The Conspirator has been donated to help replicate the trial room. But because the military base is policed and restricted to the general public, I’m not sure what their plans are to allow the publc access after it is completed. In any case, if you do get there, there is a tennis court that sits south of the building. The location of the scaffold was located just off the playing surface (northeast corner) of Court #4. I’ve stood on the exact spot and your mind can take you back to July 7, 1865 and the executions. Although interesting, it can also be a bit uncomfortable. When I was on the set of The Conspirator and stood by their replcated scaffold, it gave a good scale of the size of the event and how the event likely took place (more or less). I’ve written in the past about the ‘changes to the real history’ that were made in the movie for ‘storytelling reasons’ but overall it was a really good effort.
I have been promising to post a plan of the original pentitentiary and superimpose it over a photograph of the existing site. It really helps you to get oriented when you see it. I will definitely get to that soon. If you do get to the site, please let me know. I’d like to know what you think.

I’ve read that Union cavalrymen were posted from the White House to the Penitentiary on 7 Jul 1865 to act as a relay in case Mary Surratt was given a pardon. Any idea what unit these horsemen belonged to? Were they the same guards shown in the courtroom sketches that appeared in the papers of the time? Thanks. Great site.
Hi Bob: Thanks for your comment. You are correct that a series of mounted soldiers were posted between the Arsenal and the White House in anticipation that a reprieve would be issued by President Johnson on behalf of Mary Surratt. General Hancock gave the order for this through General Hartranft. As to the actual unit that these cavalrymen came from, regrettably I do not know. There were many different regiments assigned to the event that day and details are often mixed up and confusing. I will look into it more for you and if I find a logical and solid answer, I will let you know.
Regarding whether they were the same soldiers that guarded the courtroom, I’d say that this is not the case. These guards were mostly VRC soldiers and were rotated out on a regular basis for security purposes as per directions from Lafayette Baker.
Thanks again.

Abraham Lincoln had the prison population removed and used the penitentiary as an arsenal. As a civil war collector, a known variant of a .58 conical shaped minie ball has a star punched in its cavity known as a “Washington Arsenal”. Were these bullets manufactured here or the penitentiary served only as storage.
Hi Anthony. Thanks for your comment. I am not as familiar with the ‘arsenal’ functions as it relates to your question. I am fascinated about the minie ball with the “Washington Arsenal” name sake. I have three different written histories on the Washington Arsenal as well as good contacts at Fort McNair. Let me see if I can find out if there are any references to the manufacturing facilities from the past and if there is any information on minie ball production. Do you know if this particular minie ball was Civil War era or could it be from an earlier period?
Thanks again.

Barry
Hi Barry,
Best to my knowledge this ball was most likely produced only during the Civil War era, not from a prior period (the quality of manufacture looks consistent to small arms ammunition of the period) nor later, as the muzzle loader gave way to breech loaders and brass cartridges.
