Gettysburg at 50: The Great Reunion of 1913

Library of Congress

From June 29 to July 6, 1913, the Union and Confederate flags flew side by side when more than 50,000 Civil War veterans convened in Gettysburg, Pennsylvania, to commemorate the 50th anniversary of one of the most pivotal battles in American history. Here’s a closer look at the Great Reunion of 1913.

The Idea

In April 1908, General H. S. Huidekoper, a Philadelphia native who lost his right arm at Gettysburg in 1863, suggested a fitting semicentennial observance of the three-day battle to Pennsylvania Governor Edwin S. Stuart.

Stuart, who presented the idea to the state’s General Assembly in January 1909 and established the Fiftieth Anniversary of the Battle of Gettysburg Commission later that year, envisioned a reunion of Union and Confederate soldiers that would be talked about for years to come. “Other States, both north and south, whose sons fought at Gettysburg, will surely co-operate in making the occasion one that will stand foremost in the martial history of the world,” he said.

Several reunions had been held at Gettysburg before, including one to commemorate the 15th anniversary, but this one would trump them all.

The Planning

John K. Tener, a former major league baseball player who succeeded Stuart as Pennsylvania Governor in 1911, oversaw most of the planning for the reunion. Invitations were extended to all Civil War veterans and the Commission called upon the National Government and individual states to appropriate funds for travel to and from Gettysburg, predominantly by rail.

With assistance from the War Department, the Commission helped prepare Gettysburg, a town of 4,500, for the 100,000 visitors (about half of them non-veterans) expected to attend the reunion. The official celebration would be held from July 1 (Veteran’s Day) to July 4.

The Great Camp

The camp for the veterans at Gettysburg officially opened on June 29, and the first meal of the reunion was served that evening. About 25,000 veterans, including Major Gen. Daniel E. Sickles, the only surviving corps commander on either side, arrived on the first day.

The camp comprised 280 acres and more than 5,000 tents, which were organized by state and equipped with two hand basins and a water bucket. Artesian wells were installed in the months leading up to the reunion to supply water to the veterans’ village. According to the Commission’s report, there were 53,407 veterans in camp. In addition, 124 officers and 1,342 enlisted men were assigned by the War Department to help make sure things ran smoothly, while 155 newspapermen and 2,170 cooks brought the total in camp to 57,198.

Only veterans with the proper credentials, such as honorable discharge or pension papers, were fed and sheltered in the camp. Most of the 50,000 non-veterans who traveled to Gettysburg to share in the celebration were housed at Gettysburg College.

Exercises in the Great Tent

Public exercises were held July 1-4 in a giant tent, equipped with 13,000 chairs, inside the camp. Colonel J.M. Schoonmaker, the chairman of the Pennsylvania Commission, opened the ceremonies on July 1 at 2 p.m. Dedications of state monuments followed. The second day of the reunion, Military Day, featured a reading of Abraham Lincoln’s Gettysburg Address and the introduction of members of Union Gen. George G. Meade’s family. July 3, Governor’s Day, featured 65 regimental reunions, speeches by more than a dozen Governors, a flag ceremony at the site of Pickett’s charge, and a fireworks display. An address by President Woodrow Wilson highlighted the festivities on the Fourth of July.

Sweltering Conditions

Temperatures climbed into the triple digits on the first few days of the reunion. According to a report by the U.S. Army’s Chief Surgeon, 744 cases were admitted to the camp’s hospitals, and 319 of those were for heat exhaustion. (Sunstroke and tonsillitis each accounted for one case.) There were nine fatalities during the reunion, but considering the mean age of the veterans present was 72 and that most had traveled hundreds of miles to attend, it’s a wonder that number wasn’t greater. The post-reunion report by the Pennsylvania Commission declared the number of fatalities as “nothing short of marvelous.”

Food and Supplies

Cooks served 688,000 meals from June 29 to July 6. The great camp was stocked with 156,410 pounds of meat, 14,722 pounds of fowl, 7,008 cans of fish, 24,930 dozen eggs, 12,383 pounds of butter, and 403 gallons of pickles, among many other provisions. The dessert menu included 2,015 gallons of ice cream and 7,000 pies. Unused meat and vegetables were sold at auction after the camp closed. Fifty-four thousand mess kits were provided to the veterans as souvenirs. Each mess kit contained a fork, knife, small and large spoon, tin cup, and two plates. Veterans were asked to bring their own towels and toiletries.

Reunions Within the Reunion

When they weren’t taking in the scheduled public exercises at the reunion, veterans spent their time in Gettysburg reminiscing with friends and getting to know former foes. It was common for a veteran to seek out a man who may have shot him or exchange badges with a soldier from the other side. Two men reportedly purchased a hatchet at a local hardware store, walked it to the site where their regiments fought, and buried it. Here are three of the more interesting mini-reunions mentioned in the Pennsylvania Commission’s report and various newspaper accounts:

Flower Girls
When Gen. John Buford’s blue-uniformed soldiers rode through the streets of Gettysburg on June 30, 1863, a throng of girls in white dresses greeted them. The girls sang patriotic songs and threw flowers while standing on grocery boxes to get a better look at the troops. “It was a mighty cheering preparation for the fight of the next day,” one member of the Sixth New York Cavalry recalled.

Fifty years later, the members of the Sixth New York Cavalry who returned to Gettysburg combed the town in search of surviving members of that welcoming party. They found six women, who were brought to camp for an impromptu reunion. “We wish to thank you and say ‘God bless you’ for the friendly greeting you extended to us in those days so long ago, when kind words from gentle and noble women were like an oasis in a desert,” one member of the Sixth said. The women then sang a stirring rendition of “Rally Round the Flag.”

Bragging Rights
An op-ed in The New York Times during the reunion mentioned that many veterans reminisced about their experiences at Gettysburg in 1863 as they would a baseball contest. A separate article described the scene of a Union and a Confederate soldier posing for a photo by shaking hands next to a cannon. The Union soldier turned to the Confederate and said, “I’m mighty glad to do this, you know; but still, you know, we did lick you.”

“You Are the Man”
Yet another New York Times article detailed an encounter between a Confederate soldier who was shot at the Bloody Angle, and would have died, were it not for a Union soldier who came to his rescue. A Union soldier who heard this story told the Confederate that he had saved a Confederate at the Bloody Angle that day, describing exactly what he had done. The Confederate examined the Union soldier more closely and declared, “But my God, that’s just what the Yankee did for me. There couldn’t have been two cases like that at the same time. You are the man.”

President Wilson’s Address

President Wilson initially declined the invitation to the reunion, having established a personal rule not to leave Washington for any speechmaking occasion while Congress was in session, but he ultimately reconsidered and decided to attend. Wilson addressed the camp at 11 a.m. on the Fourth of July and left after the playing of the National Anthem. The process of shutting down the camp began soon after. The hospital closed on July 5, fewer than 300 veterans remained on the night of July 6, and the last veteran left on July 8.

1938 Reunion

A 75th anniversary reunion was held in 1938, but as you might imagine, most Civil War veterans had passed away by then. About 25 veterans who had fought at Gettysburg and 2,000 other veterans attended.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning
May 21, 2017

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!

8 Common Dog Behaviors, Decoded
May 25, 2017

Dogs are a lot more complicated than we give them credit for. As a result, sometimes things get lost in translation. We’ve yet to invent a dog-to-English translator, but there are certain behaviors you can learn to read in order to better understand what your dog is trying to tell you. The more tuned-in you are to your dog’s emotions, the better you’ll be able to respond—whether that means giving her some space or welcoming a wet, slobbery kiss. 

1. What you’ll see: Your dog is standing with his legs and body relaxed and tail low. His ears are up, but not pointed forward. His mouth is slightly open, he’s panting lightly, and his tongue is loose. His eyes? Soft or maybe slightly squinty from getting his smile on.

What it means: “Hey there, friend!” Your pup is in a calm, relaxed state. He’s open to mingling, which means you can feel comfortable letting friends say hi.

2. What you’ll see: Your dog is standing with her body leaning forward. Her ears are erect and angled forward—or have at least perked up if they’re floppy—and her mouth is closed. Her tail might be sticking out horizontally or sticking straight up and wagging slightly.

What it means: “Hark! Who goes there?!” Something caught your pup’s attention and now she’s on high alert, trying to discern whether or not the person, animal, or situation is a threat. She’ll likely stay on guard until she feels safe or becomes distracted.

3. What you’ll see: Your dog is standing, leaning slightly forward. His body and legs are tense, and his hackles—those hairs along his back and neck—are raised. His tail is stiff and twitching, not swooping playfully. His mouth is open, teeth are exposed, and he may be snarling, snapping, or barking excessively.

What it means: “Don’t mess with me!” This dog is asserting his social dominance and letting others know that he might attack if they don’t defer accordingly. A dog in this stance could be either offensively aggressive or defensively aggressive. If you encounter a dog in this state, play it safe and back away slowly without making eye contact.

4. What you’ll see: As another dog approaches, your dog lies down on his back with his tail tucked in between his legs. His paws are tucked in too, his ears are flat, and he isn’t making direct eye contact with the other dog standing over him.

What it means: “I come in peace!” Your pooch is displaying signs of submission to a more dominant dog, conveying total surrender to avoid physical confrontation. Other, less obvious, signs of submission include ears that are flattened back against the head, an avoidance of eye contact, a tongue flick, and bared teeth. Yup—a dog might bare his teeth while still being submissive, but they’ll likely be clenched together, the lips opened horizontally rather than curled up to show the front canines. A submissive dog will also slink backward or inward rather than forward, which would indicate more aggressive behavior.

5. What you’ll see: Your dog is crouching with her back hunched, tail tucked, and the corner of her mouth pulled back with lips slightly curled. Her shoulders, or hackles, are raised and her ears are flattened. She’s avoiding eye contact.

What it means: “I’m scared, but will fight you if I have to.” This dog’s fight or flight instincts have been activated. It’s best to keep your distance from a dog in this emotional state because she could attack if she feels cornered.

6. What you’ll see: You’re staring at your dog, holding eye contact. Your dog looks away from you, tentatively looks back, then looks away again. After some time, he licks his chops and yawns.

What it means: “I don’t know what’s going on and it’s weirding me out.” Your dog doesn’t know what to make of the situation, but rather than nipping or barking, he’ll stick to behaviors he knows are OK, like yawning, licking his chops, or shaking as if he’s wet. You’ll want to intervene by removing whatever it is causing him discomfort—such as an overly grabby child—and giving him some space to relax.

7. What you’ll see: Your dog has her front paws bent and lowered onto the ground with her rear in the air. Her body is relaxed, loose, and wiggly, and her tail is up and wagging from side to side. She might also let out a high-pitched or impatient bark.

What it means: “What’s the hold up? Let’s play!” This classic stance, known to dog trainers and behaviorists as “the play bow,” is a sign she’s ready to let the good times roll. Get ready for a round of fetch or tug of war, or for a good long outing at the dog park.

8. What you’ll see: You’ve just gotten home from work and your dog rushes over. He can’t stop wiggling his backside, and he may even lower himself into a giant stretch, like he’s doing yoga.

What it means: “OhmygoshImsohappytoseeyou I love you so much you’re my best friend foreverandeverandever!!!!” This one’s easy: Your pup is overjoyed his BFF is back. That big stretch is something dogs don’t pull out for just anyone; they save that for the people they truly love. Show him you feel the same way with a good belly rub and a handful of his favorite treats.

The best way to say “I love you” in dog? A monthly subscription to BarkBox. Your favorite pup will get a package filled with treats, toys, and other good stuff (and in return, you’ll probably get lots of sloppy kisses). Visit BarkBox to learn more.
