On July 30, 1419, Czech priest Jan Želivský was leading his congregation through the streets of Prague to protest corruption in the Catholic church when someone threw a stone at him from the window of the town hall. His followers stormed the hall and threw 13 members of the town council from a high window, killing them.

Remarkably, the same thing happened again in 1618, when King Ferdinand dissolved the Protestant estates in Bohemia. Aggrieved Protestants confronted Catholic officials in the chancellory and threw several of them from a third-floor window. All three survived — Catholics contended that they had been saved by angels, Protestants that they had landed on a dunghill. (Or, a reader suggests, “the Czechs bounced.”)

When minister Francis Bellamy published the American Pledge of Allegiance in Youth’s Companion in 1892, his colleague James Upham devised a salute to go along with it, snapping the heels together and extending the right arm toward the flag:

At a signal from the Principal the pupils, in ordered ranks, hands to the side, face the Flag. Another signal is given; every pupil gives the flag the military salute — right hand lifted, palm downward, to a line with the forehead and close to it. Standing thus, all repeat together, slowly, ‘I pledge allegiance to my Flag and the Republic for which it stands; one Nation indivisible, with Liberty and Justice for all.’ At the words, ‘to my Flag,’ the right hand is extended gracefully, palm upward, toward the Flag, and remains in this gesture till the end of the affirmation; whereupon all hands immediately drop to the side.

This worked fine until the 1920s, when Italian fascists and then German Nazis adopted similar salutes. Congress delicately changed the American salute to the hand-on-heart gesture in 1942.

After the San Francisco earthquake, James Jones wrote this letter on a detachable shirt collar and mailed it without postage to his son and daughter-in-law in New York:

Dear Wayland and Gussie: All safe but awfully scared. Frisco and hell went into partnership and hell came out winner — got away with the sack. Draw a line from Ft Mason along Van Ness Ave. to Market St., out Market to Dolores to Twentieth, thence to Harrison, 16th & Portrero Ave. R.R. Ave. to Channel St. and bay. Nearly everything east and north of this boundary line gone, and several blocks west of it, especially in Hayes Valley as far as Octavia St. from Golden Gate Ave. east. Fire is still burning on the northside but is checked in the Mission. I and a band of 40 or 50 volunteers formed a rope and bucket brigade, back-fired Dolores from Market to 19th, pulled down houses and blanketed westside Dolores and won a great victory. More with paper & stamps. James G. Jones. April 21st, 1906.

It was delivered. The post office had resolved to handle “everything, stamped or unstamped, as long as it had an address to which it could be sent,” remembered William F. Burke, secretary to the city postmaster. When he made the rounds of camps, “the wonderful mass of communications that poured into the automobile was a study in the sudden misery that had overtaken the city. Bits of cardboard, cuffs, pieces of wrapping paper, bits of newspapers with an address on the margin, pages of books and sticks of wood all served as a means to let somebody in the outside world know that friends were alive and in need among the ruins.”

At the close of the first day, “95 pouches of letters carrying mail composed of rags and tatters and odds and ends — and burdened with a weight of woe bigger than had ever left the city in a mail sack — were made up for dispatch. … It came to our knowledge later that not one piece of this mail that was properly addressed failed of delivery.”

Shot down over South Vietnam in 1972, Air Force navigator Iceal Hambleton needed to reach the Cam Lo River but was surrounded by enemy forces who might intercept any radio messages sent to him. After some consultation, rescuers told him to play the first hole at the Tucson National Golf Course. “Before you start be damned sure you line your shot up properly,” they said. “Very bad traps on this hole.”

Hambleton was bewildered at first but came to understand. As an avid golfer he was familiar with a number of American courses, and he had a photographic memory of each hole’s length and layout. The first hole at Tucson was 430 yards long and ran southeast, so he set off accordingly across country, following an imaginary fairway.

This worked. By invoking additional holes from three Air Force bases, as well as a par 3 from Augusta National, rescuers led Hambleton to the river, where a Navy SEAL picked him up.

“Two things kept me alive,” he told Golf Digest in 2001. “The will to live, and my wife. And we’re playing golf Friday.”

During the hyperinflation that followed World War I in the Weimar Republic, a 5,000-mark cup of coffee could cost 8,000 marks by the time it was drunk. Newspapers published the stupefying multipliers by which prices had risen each day:

Tramway fare: 50,000
Tramway monthly season ticket:
— For one line: 4 million
— For all lines: 12 million
Taxi-autos: multiply ordinary fare by: 600,000
Horse cabs: multiply ordinary fare by: 400,000
Bookshops: multiply ordinary price by: 300,000
Public baths: multiply ordinary price by: 115,000
Medical attendance: multiply ordinary price by: 80,000

By the end of 1923 there were 92,844,720,742,927,000,000 marks circulating in the German economy, nearly 93 quintillion (note the logarithmic scale in the chart above).

This had a curious psychological effect. In December Time reported, “With the price of bread running into billions a loaf the German people have had to get used to counting in thousands of billions. This, according to some German physicians, brought on a new nervous disease known as ‘zero stroke,’ or ‘cipher stroke,'” a “desire to write endless rows of [zeros] and engage in computations more involved than the most difficult problems in logarithms.”

Human minds are not made to comprehend such large numbers. Foreign minister Walther Rathenau called it the “delirium of milliards”: “What is a milliard? Does a wood contain a milliard leaves? Are there a milliard blades of grass in a meadow? Who knows? If the Tiergarten were to be cleared and wheat sown upon its surface, how many stalks would grow?”

Fortunately the madness was stemmed with the introduction of a new currency — in 1924 one could exchange a trillion of the old marks for a single new Rentenmark, and the economy was finally stabilized.

Cleveland Press reporter John Raper took a vacation in New Mexico in 1944 and came back with a sensational story — he had discovered a “mystery city” there, a closely policed community at work on some top-secret project northwest of Santa Fe.

Uncle Sam has placed this in charge of two men. The man who commands the soldiers, who sees that the garbage and rubbish are collected, the streets kept up, the electric light plan and the waterworks functioning and all other metropolitan work operating smoothly is a Col. Somebody. I don’t know his name, but it isn’t so important because the Mr. Big of the city is a college professor, Dr. J. Robert Oppenheimer, called ‘the Second Einstein’ by the newspapers of the west coast. …

It is the work of Prof. Oppenheimer and the hundreds of men and women in his laboratories and shops that makes Los Alamos such a carefully guarded city. All the residents will be obliged to remain there for the duration and for six months thereafter and it seems quite probable that many of them don’t know much more about what is being done than you do.

Apparently Raper had driven into the compound to investigate but was escorted closely and allowed to see nothing. He told curious New Mexicans, “I don’t know a bit more about it than I did before I went.” Santa Fe residents whispered that Oppenheimer was building some sort of chemical weapon, an explosive, or “a beam that will cause the motors to stop so that German planes will drop from the skies as though they were paving blocks.” But all of this appeared to be rumor.

Raper published his story in the newspaper on March 13. It provoked an immediate stir among the Manhattan Project authorities, who quashed a followup story in TIME and briefly considered having Raper drafted into the Pacific Theater. But ultimately nothing came of it, and no Axis spy seems to have pursued it. American Institute of Physics science historian Alex Wellerstein discusses the story, and provides the full text with its lurid illustrations, on his Restricted Data blog.

After John II of France was captured by the English in 1356, he paid 1 million gold crowns for his ransom and promised to pay 2 million more. As a guarantee he offered his son Louis as a hostage. When word came that Louis had escaped, John voluntarily returned to captivity in England, citing reasons of “good faith and honor.” He died there in 1364.

In 1916, after two years in a German prisoner-of-war camp, British Army captain Robert Campbell received word that his mother was dying of cancer. He wrote to Kaiser Wilhelm II asking permission to visit her, and was given two weeks’ leave on condition that he return afterward. Campbell went to England, spent a week with his dying mother, then returned to confinement in Germany, where he remained until the war ended.

“Captain Campbell was an officer, and he made a promise on his honor to go back,” said historian Richard Van Emden, who uncovered the episode while researching his book Meeting the Enemy. “Had he not turned up there would not have been any retribution on any other prisoners. What I think is more amazing is that the British Army let him go back to Germany.”

German shipyard worker August Landmesser openly loved a Jewish woman under the gathering cloud of Nazism in the 1930s. He had joined the party hoping it would help him to find a job, but was expelled when he became engaged to Irma Eckler in 1935. Unwilling to renounce their love, the two were forbidden to marry, prevented from fleeing to Denmark in 1937, and eventually sent to concentration camps.

The photograph above was taken at the launch of the naval training vessel Horst Wessel on June 13, 1936, a year after their engagement. The man in the center, the only one not giving the Nazi salute, is believed to be Landmesser.

On Sept. 9, 1900, the day after a strong storm made landfall on the Texas coast, the U.S. Weather Bureau wired Western Union, Do you hear anything about Galveston?

The first response was We have been absolutely unable to hear a word from Galveston since 4 p.m. yesterday …. But then:

First news from Galveston just received by train which could get no closer to the bay shore than six miles, where Prairie was strewn with debris and dead bodies. About two hundred corpses counted from train. Large Steamship stranded two miles inland. Nothing could be seen of Galveston. Loss of life and property undoubtedly most appalling.

The storm had put the entire city under 8 to 15 feet of water and lashed it with winds reaching 145 mph. With 8,000 dead, it remains the deadliest natural disaster in U.S. history. Following is the only account known to have been written while the storm was taking place — it’s an unsigned letter by a woman, probably a nurse, who was employed at the John Sealy Hospital:

A.M.
It does not require a great stretch of imagination to imagine this structure a shaky old boat out at sea. The whole thing rocking like a reef, surrounded by water, said water growing closer, ever closer. Have my hands full quieting nervous, hysterical women.

12-noon.
Things beginning to look serious. Water up to the first floor in the house, all over the basement of the hospital. Cornices, roofs window lights blinds flying in all directions.

The scenes about here are distressing. Everything washed away. Poor people trying, vainly to save their bedding, & clothing. Methinks the poor nurses will be trying to save their beds in short order. Now flames in the distance. It is all a grand, fine sight. Our beautiful Bay, a raging torrent.

3 p.m.
Am beginning to feel a weakening desire for something ‘to cling to.’ Should feel more comfortable in the embrace of your arms. You hold yourself in readiness to come to us? Should occasion demand? Darkness is overwhelming us, to add to the horror. Dearest — I — reach out my hand to you. My heart — my soul.

That’s all we have — we don’t know who wrote the letter, or whether she survived the storm (the hospital remained standing).

According to some survivors, we’re lucky to have any accounts at all. “One hour more of that wind would have killed every person on the island,” wrote Walker W. Davis, a salesman who waited out the storm in the Tremont Hotel.

Margaret Rowan Bettencourt, who was 9 years old at the time, remembered that the East End, where her grandmother’s house was located, was largely reduced to splinters. “They never would’ve found her place, but my aunt had a ‘polly’ [parrot] that was up in the attic and the attic didn’t go to pieces. It just sat on the top of the house and the next morning the polly was hollering ‘Pretty Polly. Pretty Polly.’ That’s how they found where they lived.”
