The Duke of Wellington forbade officers to carry umbrellas into battle. On Dec. 10, 1813, during the Peninsular War, he saw a group of Grenadier Guards sheltering from the rain and sent an angry message: “Lord Wellington does not approve of the use of umbrellas during the enemy’s firing, and will not allow the gentlemen’s sons to make themselves ridiculous in the eyes of the army.” He later reproved their commander, saying, “The Guards may in uniform, when on duty at St. James’s, carry them if they please, but in the field it is not only ridiculous but unmilitary.”

Spectacles were not allowed in the British army until 1902. “There is little doubt that England will soon realize that she must take her place in company with the Continental people and furnish glasses as they do,” the Medical News had opined that March. It quoted ophthalmologist John Grimshaw, who had asked invalided South African soldiers whether their eyes had given them trouble in shooting on the veldt.

“Fightin’ all day, sir, and never saw a Boer,” one had replied. “Yes, sir, we simply blazed away at the kopjes on the chance of hittin’ a Boer or two.”

In August 1942 a students’ nursing brigade discovered 12-year-old Tanya Savicheva, weak with hunger, living alone in an apartment in Leningrad, which had been besieged by Hitler since September 1941. She had kept this diary:

1. Zhenya died on December 18, 1941, at twelve noon.
2. Grandma died on January 25, 1942, at three in the afternoon.
3. Leka died on March 17, 1942, at five o’clock in the morning.
4. Uncle Vasya died on April 13, 1942, at two o’clock at night.
5. Uncle Lesha on May 10, 1942, at four o’clock in the afternoon.
6. Mama died on May 13, 1942, at 7:30 in the morning.
7. The Savichevs are dead.
8. Everyone is dead.
9. Only Tanya is left.

The nurses evacuated her along the narrow lifeline that had been opened that summer by the Soviet army and placed her in an orphanage in a nearby village, but she died there, probably of chronic dysentery, in July 1944. The diary is kept today in the St. Petersburg Museum of History.

Around 1275, a native culture known as the Gallina vanished from northern New Mexico. And almost every Gallina skeleton ever found has been that of someone brutally murdered. No one knows why.

“[Someone] was just killing them, case after case, every single time,” U.S. Forest Service archaeologist Tony Largaespada told National Geographic News in 2007.

Seven skeletons found in a remote canyon paint a typical picture — one had a fractured skull, forearm, jaw, thighbone, pelvis, and several broken ribs; another bore cut marks on the upper arm that suggested blows from an ax. A 2-year-old child had had its skull crushed.

In other cases the victims’ necks have been broken, and the bodies are commonly thrown into a house, which is then burned to the ground.

Possibly this was a genocide, or possibly internecine conflict within the Gallina. Either could have been exacerbated by a drought that is known to have gripped the area around this time. But, so far, no one knows the reason.

When Germany invaded the Soviet Union in 1941, it interrupted one of the most ambitious building projects in history. Situated near the Kremlin, the Palace of the Soviets would have commemorated the founding the U.S.S.R. with a 21,000-seat congress hall, 100 stories of administrative offices, and a crowning statue of Lenin 75 meters tall.

It would have been both the largest and the tallest building in the world. But only the foundation had been built when the war intervened, and the frame was disassembled for its steel. Construction never resumed, and in the 1960s the site was turned into an open-air swimming pool. This must symbolize something.

In 1777, British general Sir Henry Clinton sent this message to his fellow officer John Burgoyne, lamenting that he’d be unable to join him in a plan to divide the colonies along the Hudson River:

This was a ruse — Clinton’s real meaning can be revealed by applying a mask:

Historians aren’t certain whether the message reached Burgoyne or influenced his decisions. As it happened, Clinton didn’t participate in the conflict, and Burgoyne lost the Battle of Saratoga, the turning point of the war.

As a boy Harry Truman practiced piano for two hours a day. “My choice early in life was either to be a piano player in a whorehouse or a politician,” he said later. “And to tell the truth, there’s hardly any difference.”

At age 12 he attended a concert by Paderewski. “And I was studying the Minuet by Paderewski. And when he got through with his concert — which was a wonder — he played that Chopin A-Flat Waltz, Opus 42, which has always been a favorite of mine. And he played the waltz rendition of the Blue Danube, and so on.”

“When we went back behind the scenes, [my teacher] took me with her, and it almost scared me to death. She told him I didn’t know how to make ‘the turn’ in the minuet, and he said, ‘Sit down,’ and he showed me how to do it. I played it at Postdam for old Stalin. I think he was quite impressed.”

He gave up piano because “it was a sissy thing to do. So I just stopped. And it was probably all for the best. I wouldn’t ever have been really first-rate. A good music-hall piano player is about the best I’d have ever been. So I went into politics and became president of the United States.”

To give his “Infamy” speech on the day after Pearl Harbor, Franklin Roosevelt rode to the Capitol in a car owned by Al Capone.

The Secret Service was concerned about assassination attempts, and Roosevelt’s regular state car had no protective features. So the president made use of Capone’s heavily armored 1928 Cadillac 341A Town Sedan, which the Treasury Department had impounded after the gangster’s arrest.

On July 1, 1916, the first day of the Battle of the Somme, British Army captain Wilfred Nevill needed a way to keep the East Surrey Regiment’s B Company organized and advancing toward the German trenches. He had been told that continuous shelling had left nothing alive in the German lines, but night patrols had shown him this wasn’t true.

So Nevill produced four footballs, one for each of his platoons to kick across no man’s land as they charged the German position.

Private L.S. Price of the 8th Royal Sussex, who was looking on, recalled, “As the gunfire died away I saw an infantryman climb onto the parapet into no man’s land, beckoning others to follow. As he did so he kicked off a football; a good kick, the ball rose and travelled well towards the German line. That seemed to be the signal to advance.”

The four platoons followed suit, kicking their balls continuously across 300 yards of ground to reach the German trenches. Twenty thousand British soldiers were killed that day, including Nevill, who was shot when they reached the barbed wire, but his company gained its objective. The Daily Mail commemorated their charge with a poem:

On through the hail of slaughter,
Where gallant comrades fall,
Where blood is poured like water,
They drive the trickling ball.
The fear of death before them
Is but an empty name;
True to the land that bore them,
The Surreys played the game.

Two of the footballs have been recovered. One is in the National Army Museum, the other at the Queen’s Regiment Museum, Howe Barracks, Canterbury.
