Why Some Civil War Soldiers Glowed in the Dark

By the spring of 1862, a year into the American Civil War, Major General Ulysses S. Grant had pushed deep into Confederate territory along the Tennessee River. In early April, he was camped at Pittsburg Landing, near Shiloh, Tennessee, waiting for Maj. Gen. Don Carlos Buell’s army to meet up with him.

On the morning of April 6, Confederate troops based out of nearby Corinth, Mississippi, launched a surprise offensive against Grant’s troops, hoping to defeat them before the second army arrived. Grant’s men, augmented by the first arrivals from the Ohio, managed to hold some ground, though, and establish a battle line anchored with artillery. Fighting continued until after dark, and by the next morning, the full force of the Ohio had arrived and the Union outnumbered the Confederates by more than 10,000.

The Union troops began forcing the Confederates back, and while a counterattack stopped their advance it did not break their line. Eventually, the Southern commanders realized they could not win and fell back to Corinth until another offensive in August (for a more detailed explanation of the battle, see this animated history).

All told, the fighting at the Battle of Shiloh left more than 16,000 soldiers wounded and more 3,000 dead, and neither federal or Confederate medics were prepared for the carnage.

The bullet and bayonet wounds were bad enough on their own, but soldiers of the era were also prone to infections. Wounds contaminated by shrapnel or dirt became warm, moist refuges for bacteria, which could feast on a buffet of damaged tissue. After months marching and eating field rations on the battlefront, many soldiers’ immune systems were weakened and couldn’t fight off infection on their own. Even the army doctors couldn’t do much; microorganisms weren’t well understood and the germ theory of disease and antibiotics were still a few years away. Many soldiers died from infections that modern medicine would be able to nip in the bud.

A Bright Spot

Some of the Shiloh soldiers sat in the mud for two rainy days and nights waiting for the medics to get around to them. As dusk fell the first night, some of them noticed something very strange: their wounds were glowing, casting a faint light into the darkness of the battlefield. Even stranger, when the troops were eventually moved to field hospitals, those whose wounds glowed had a better survival rate and had their wounds heal more quickly and cleanly than their unilluminated brothers-in-arms. The seemingly protective effect of the mysterious light earned it the nickname “Angel’s Glow.”

In 2001, almost one hundred and forty years after the battle, seventeen-year-old Bill Martin was visiting the Shiloh battlefield with his family. When he heard about the glowing wounds, he asked his mom - a microbiologist at the USDA Agricultural Research Service who had studied luminescent bacteria that lived in soil - about it.

“So you know, he comes home and, 'Mom, you're working with a glowing bacteria. Could that have caused the glowing wounds?’” Martin told Science Netlinks. “And so, being a scientist, of course I said, ‘Well, you can do an experiment to find out.’”

And that’s just what Bill did.

He and his friend, Jon Curtis, did some research on both the bacteria and the conditions during the Battle of Shiloh. They learned that Photorhabdus luminescens, the bacteria that Bill’s mom studied and the one he thought might have something to do with the glowing wounds, live in the guts of parasitic worms called nematodes, and the two share a strange lifecycle. Nematodes hunt down insect larvae in the soil or on plant surfaces, burrow into their bodies, and take up residence in their blood vessels. There, they puke up the P. luminescens bacteria living inside them. Upon their release, the bacteria, which are bioluminescent and glow a soft blue, begin producing a number of chemicals that kill the insect host and suppress and kill all the other microorganisms already inside it. This leaves P. luminescens and their nematode partner to feed, grow and multiply without interruptions.

As the worms and the bacteria eat and eat and the insect corpse is more or less hollowed out, the nematode eats the bacteria. This isn’t a double cross, but part of the move to greener pastures. The bacteria re-colonize the nematode’s guts so they can hitch a ride as it bursts forth from the corpse in search of a new host.

The next meal shouldn’t be hard to find either, since P. luminescens already sent them an invitation to the party. Just before they got got back in their nematode taxi, P. luminescens were at critical mass in the insect corpse, and scientists think that that many glowing bacteria attract other insects to the body and make the nematode’s transition to a new host much easier.

A Good Light

Looking at historical records of the battle, Bill and Jon figured out that the weather and soil conditions were right for both P. luminescens and their nematode partners. Their lab experiments with the bacteria, however, showed that they couldn’t live at human body temperature, making the soldiers’ wounds an inhospitable environment. Then they realized what some country music fans already knew: Tennessee in the spring is green and cool. Nighttime temperatures in early April would have been low enough for the soldiers who were out there in the rain for two days to get hypothermia, lowering their body temperature and giving P. luminescens a good home.

Based on the evidence for P. luminescens’s presence at Shiloh and the reports of the strange glow, the boys concluded that the bacteria, along with the nematodes, got into the soldiers’ wounds from the soil. This not only turned their wounds into night lights, but may have saved their lives. The chemical cocktail that P. luminescens uses to clear out its competition probably helped kill off other pathogens that might have infected the soldiers’ wounds. Since neither P. luminescens nor its associated nematode species are very infectious to humans, they would have soon been cleaned out by the immune system themselves (which is not to say you should be self-medicating with bacteria; P. luminescens infections can occur, and can result in some nasty ulcers). The soldiers shouldn’t have been thanking the angels so much as the microorganisms.

As for Bill and Jon, their study earned them first place in team competition at the 2001 Intel International Science and Engineering Fair.

14 Facts About International Talk Like A Pirate Day

Ahoy, me hearties! As many of you know, September 19 is International Talk Like A Pirate Day, an annual phenomenon that’s taken the world by storm, having been observed by every continent, the International Space Station, and even the Oval Office since it first made headlines back in 2002. So let’s hoist the Jolly Roger, break out the rum, and take a look back at the holiday’s timber-shivering history.

1. Talk Like a Pirate Day was originally conceived of on D-Day.

Talk Like a Pirate Day creators John Baur and Mark Summer (who’ve since acquired the nicknames “Ol’ Chumbucket” and “Cap’n Slappy,” respectively) created the holiday while playing racquetball on June 6, 1995—the 51st anniversary of the invasion of Normandy. Out of respect to the battle’s veterans, a new observance date was quickly sought.

2. September 19th also happens to be the birthday of the ex-wife of the holiday's co-creator.

“[September 19th was] the only date we could readily recall that wasn’t already taken up with Christmas or the Super Bowl or something,” the pair later claimed. Summers claims to harbor no ill will toward his former spouse, who has since stated, “I’ve never been prouder to be his ex-wife!

3. Pulitzer Prize-winning humorist Dave Barry is largely responsible for popularizing the holiday.

Dave Barry was so smitten with the holiday after having been introduced to it via email in early 2002 that he dedicated an entire column to its publicity that September, turning an inside joke into a global sensation. He later went on to make a cameo appearance in one of Baur and Summers’s buccaneer-themed music videos in 2011 (look for him in the video above at the 3:25 mark).

4. Real pirates spoke in a wide variety of dialects.

Despite some extensive “English-to-Pirate” dictionaries that have cropped up all over the Internet the idea that all pirates shared a common accent regardless of national origin is historically absurd, as National Geographic pointed out in 2011.

5. Actor Robert Newton is hailed as the "patron saint" of Talk Like a Pirate Day.

So where did the modern “pirate dialect” come from? Summers and Baur credit actor Robert Newton's performance in Treasure Island (1950) and have accordingly dubbed him the “patron saint” of their holiday. Tasked with breathing life into the scheming buccaneer, Newton simply exaggerated his native West Country accent and the rest is history.

6. John Baur's family was featured on a pirate-themed episode of Wife Swap.

The reality show’s highly-anticipated 2006 season premiere pitted the Baurs (in full pillaging regalia) against a family which, according to John’s wife Tori (a.k.a. “Mad Sally”), “behaved as though ‘fun’ was something that had to be pre-packaged for their protection.”

7. John Baur was also on Jeopardy!

Baur was described to the audience as “a writer and pirate from Oregon” in his 2008 appearance. “I didn’t win,” Baur said, “but the introduction made Alex blink.”

8. International Talk Like a Pirate Day has become a cornerstone of the Pastafarian movement.

Bobby Henderson, founder of the Church of the Flying Spaghetti Monster, cited Earth’s dwindling pirate population as the clear source of global warming in his 2005 open letter to the Kansas school board which established the religion. Since then, Talk Like A Pirate Day has been observed by devout Pastafarians worldwide. 

9. A Florida mayor once ignited a local controversy for making an official Talk Like a Pirate Day proclamation.

In 2012, Lake Worth, Florida Mayor Pam Triolo lightheartedly urged her constituents to embrace the holiday last year, writing, “The City … is known to possess a spirit of independence, high spirits, and swashbuckling, all traits of a good pirate.” Her actions were criticized by the city’s former commissioner, Jo-Ann Golden, who took offense to the association with murderous seamen.

10. Day of the Ninja was created in response to Talk Like a Pirate Day.

Not to be outdone by their hated rivals, the pro-ninja community was quick to execute the first annual Day of the Ninja on December 5, 2002. For Summers and Baur’s take on the warring factions, see the clip above.

11. Pirates once celebrated Talk Like a Pirate Day aboard the International Space Station.

In a 2012 interview, Summers recalled being “informed that the astronauts on the International Space Station were awakened to ‘A Pirate’s Life For Me' and joined in the pirate talk from space.”

12. President Obama once celebrated with a costumed buccaneer in the Oval Office.

In 2012, Barack Obama tweeted this image on Talk Like a Pirate Day with the caption “Arr you in?”

13. A congressman later used the holiday to slam President Obama's tax plan.

In 2011, Florida’s 12th congressional district representative Dennis Ross used the festivity as a political punchline after Obama made a speech detailing his tax plan, tweeting, “It is TALK like a pirate day … not ACT like one. Watch ye purses and bury yr loot, the taxman cometh.”

14. It's an official holiday in the state of Michigan.

On June 4, 2013, state senator Roger Kahn’s proposal to grant International Talk Like A Pirate Day official acknowledgement from the Michigan government was formally adopted, to the chagrin of some dissenting landlubbers.

10 Fast Facts About Jimi Hendrix

Though he’s widely considered one of the most iconic musicians of the 20th century, Jimi Hendrix passed away as his career was really just getting started. Still, he managed to accomplish a lot in the approximately four years he spent in the spotlight, and leave this world a legend when he died on September 18, 1970, at the age of 27. Here are 10 things you might not have known about the musical legend.

1. Jimi Hendrix didn't become "Jimi" until 1966.

Jimi Hendrix was born in Seattle on November 27, 1942 as John Allen Hendrix. He was initially raised by his mother while his father, James “Al” Hendrix, was in Europe fighting in World War II. When Al returned to the United States in 1945, he collected his son and renamed him James Marshall Hendrix.

In 1966, Chas Chandler—the bassist for The Animals, who would go on to become Jimi’s manager—saw the musician playing at Cafe Wha? in New York City. "This guy didn't seem anything special, then all of a sudden he started playing with his teeth," roadie James "Tappy" Wright, who was there, told the BBC in 2016. "People were saying, 'What the hell?' and Chas thought, 'I could do something with this kid.’”

Though Hendrix was performing as Jimmy James at the time, it was Chandler who suggested he use the name “Jimi.”

2. Muddy Waters turned Jimi Hendrix on to the guitar—and scared the hell out of him.

When asked about the guitarists who inspired him, Hendrix cited Buddy Holly, Eddie Cochran, Elmore James, and B.B. King. But Muddy Waters was the first musician who truly made him aware of the instrument. “The first guitarist I was aware of was Muddy Waters,” Hendrix said. “I heard one of his old records when I was a little boy and it scared me to death because I heard all these sounds.”

3. Jimi Hendrix could not read music.

In 1969, Dick Cavett asked the musician whether he could read music: “No, not at all,” the self-taught musician replied. He learned to play by ear and would often use words or colors to express what he wanted to communicate. “[S]ome feelings make you think of different colors,” he said in an interview with Crawdaddy! magazine. “Jealousy is purple—‘I'm purple with rage’ or purple with anger—and green is envy, and all this.”

4. Jimi Hendrix used his dreams as inspiration for his songwriting.

Hendrix drew inspiration for his music from a lot of places, including his dreams. “I dreamt a lot and I put a lot of my dreams down as songs,” he explained in a 1967 interview with New Musical Express. “I wrote one called ‘First Look’ and another called ‘The Purple Haze,’ which was all about a dream I had that I was walking under the sea.” (In another interview, he said the idea for “Purple Haze” came to him in a dream after reading a sci-fi novel, believed to be Philip José Farmer’s Night of Light.)

5. "Purple Haze" features one of music's most famous mondegreens.

In the same interview with New Musical Express, it's noted that the “Purple Haze” lyric “‘scuse me while I kiss the sky” was in reference to a drowning man Hendrix saw in his dream. Which makes the fact that many fans often mishear the line as “‘Scuse me, while I kiss this guy” even more appropriate. It was such a common mistake that Hendrix himself was known to have some fun with it, often singing the incorrect lyrics on stage—occasionally even accompanied by a mock make-out session. There’s even a Website, KissThisGuy.com, dedicated to collecting user-generated stories of misheard lyrics.

6. Jimi Hendrix played his guitar upside-down.

Ever the showman, Hendrix’s many guitar-playing quirks became part of his legend: In addition to playing with his teeth, behind his back, or without touching the instrument’s strings, he also played his guitar upside-down—though there was a very simple reason for that. He was left-handed. (His father tried to get him to play right-handed, as he considered left-handed playing a sign of the devil.)

7. Jimi Hendrix played backup for a number of big names.

Though Hendrix’s name would eventually eclipse most of those he played with in his early days, he played backup guitar for a number of big names under the name Jimmy James, including Sam Cooke, Little Richard, Wilson Pickett, Ike and Tina Turner, and The Isley Brothers.

In addition to the aforementioned musical legends, Hendrix also helped actress Jayne Mansfield in her musical career. In 1965, he played lead and bass guitar on “Suey,” the B-side to her single “As The Clouds Drift By.”

8. Jimi Hendrix was once kidnapped after a show.

Though the details surrounding Hendrix’s kidnapping are a bit sketchy, in Room Full of Mirrors: A Biography of Jimi Hendrix, Charles R. Cross wrote about how the musician was kidnapped following a show at The Salvation, a club in Greenwich Village:

“He left with a stranger to score cocaine, but was instead held hostage at an apartment in Manhattan. The kidnappers demanded that [Hendrix’s manager] Michael Jeffrey turn over Jimi’s contract in exchange for his release. Rather than agree to the ransom demand, Jeffrey hired his own goons to search out the extorters. Mysteriously, Jeffrey’s thugs found Jimi two days later … unharmed.

“It was such a strange incident that Noel Redding suspected that Jeffrey had arranged the kidnapping to discourage Hendrix from seeking other managers; others … argued the kidnapping was authentic.”

9. Jimi Hendrix opened for The Monkees.

Though it’s funny to imagine such a pairing today, Hendrix warming up The Monkees’s crowd of teenybopper fans actually made sense for both acts back in 1967. For the band, having a serious talent like Hendrix open for them would help lend them some credibility among serious music fans and critics. Though Hendrix thought The Monkees’s music was “dishwater,” he wasn’t well known in America and his manager convinced him that partnering with the band would help raise his profile. One thing they didn’t take into account: the young girls who were in the midst of Monkeemania.

The Monkees’s tween fans were confused by Hendrix’s overtly sexual stage antics. On July 16, 1967, after playing just eight of their 29 scheduled tour dates, Hendrix flipped off an audience in Queens, New York, threw down his guitar, and walked off the stage.

10. You can visit Jimi Hendrix's London apartment.

In 2016, the London flat where Hendrix really began his career was restored to what it would have looked like when Jimi lived there from 1968 to 1969 and reopened as a museum. The living room that doubled as his bedroom is decked out in bohemian décor, and a pack of Benson & Hedges cigarettes sits on the bedside table. There’s also space dedicated to his record collection.

Amazingly, the same apartment building—which is located in the city’s Mayfair neighborhood—was also home to George Handel from 1723 until his death in 1759; the rest of the building serves as a museum to the famed composer’s life and work.
