The Ship That Became an Island: HNLMS Abraham Crijnssen
In early March 1942, Lieutenant Commander A. van Miert gathered his crew aboard the Dutch minesweeper HNLMS Abraham Crijnssen and told them something most commanding officers never say.
He told them the truth.
The Battle of the Java Sea, fought on February 27, had been a catastrophe. The Allied fleet — Dutch, American, British, and Australian — had sailed out to stop the Japanese invasion convoys and been destroyed almost entirely. The Dutch flagship De Ruyter had gone down with her admiral. The door to Java was open. The order had gone out to every remaining Allied ship: run for Australia. Every vessel for itself.
Van Miert told his crew that he believed their odds were terrible. The Abraham Crijnssen was a minesweeper — 184 feet long, 525 tons, a top speed of 15 knots, armed with a single 3-inch gun and two 20mm cannons. Between her and Australia lay hundreds of miles of ocean now controlled by the Japanese Navy, patrolled by Japanese aircraft that could locate, report, and destroy her before she could respond. She could not outrun the planes. She could not outfight them.
He told them any man who wanted to leave had permission to go.
They stayed.
And then someone aboard the Abraham Crijnssen had an idea so simple that it should not have worked — and that worked entirely because it was so simple that no one thought to account for it.
The region around Java and the islands of the Dutch East Indies was scattered with thousands of small tropical islands — uninhabited jungle-covered rocks rising from a glittering sea, unremarkable from any altitude, indistinguishable from each other to a pilot with larger concerns. One more small tropical island would attract no attention.
So the crew of the Abraham Crijnssen cut down the jungle and brought it aboard. They lashed branches and foliage across the deck and superstructure until the angular steel shapes of a warship had disappeared under a thick green canopy. They painted the hull in grays and browns to resemble bare rock rising from the water. They worked fast, and they worked well, and when they were done the Abraham Crijnssen was no longer a warship.
She was an island. She moved only at night. By day she dropped anchor close to actual islands and sat completely still, just another piece of scenery in a sea full of it, while Japanese aircraft droned overhead.
Eight days. She arrived at Fremantle, Western Australia on March 20, 1942.
She was the last Allied vessel to successfully escape the fall of the Dutch East Indies. Every ship that had been behind her was already gone.

The Forty-Five Minute Empire: The Anglo-Zanzibar War
At eight o'clock on the morning of August 27, 1896, Sultan Khalid bin Barghash sent a message to the British consul in Zanzibar. The consul had issued an ultimatum the previous day: vacate the palace by nine o'clock or face the Royal Navy. Khalid's message said: "We have no intention of hauling down our flag and we do not believe you would open fire on us."
The consul replied that he had no desire to fire on the palace, "but unless you do as you are told, we shall certainly do so."
At nine o'clock, when Khalid had not complied, Brigadier-General Mathews gave the order. The ships waited two additional minutes to see if the Sultan would emerge. He didn't. At 9:02, HMS Thrush fired the first shot, destroying one of Khalid's artillery pieces with a single round. By 9:40, the bombardment had ceased. Khalid's flag came down. The war — if it can be called that — was over. Between 38 and 45 minutes from first shot to ceasefire, depending on the source. The shortest recorded war in history.
Five hundred of Khalid's defenders were killed or wounded. One British sailor was injured. The royal yacht HMS Glasgow was sunk; its masts were visible above the harbour waterline for the next eighteen years. Khalid himself escaped through a back door two minutes after the bombardment began, leaving his servants, guards, and conscripted civilians to die in the palace he had already vacated.
He sought asylum in the German consulate. The British surrounded it. The Germans eventually smuggled him to Dar es Salaam. During World War I the British captured him and exiled him to St. Helena — the same island where Napoleon had been imprisoned — and then to the Seychelles. Winston Churchill personally signed the letter allowing him to return to East Africa in 1922. He died in Mombasa in 1927, having never returned to Zanzibar.
The story most people know about the Anglo-Zanzibar War is that it was short. The case file is about what it was for.

The Tower That Survived by Accident: The Leaning Tower of Pisa
On August 9, 1173, construction began on a bell tower for the cathedral complex in Pisa, Italy. The foundation was three meters deep — approximately ten feet — set into a mixture of clay, fine sand, and shells on the southern bank of the Arno River. By the time the builders reached the third floor, approximately five years later, the tower had already begun to tilt.
They stopped building.
Not because they had noticed the tilt, although they had. They stopped because Pisa had gone to war with Genoa, and war required resources and attention that a bell tower did not. Construction halted for nearly a century — 99 years, by most accounts — before resuming in 1272.
Those 99 years of war and abandonment saved the tower.
Engineers analyzing the tower's survival in the twentieth century established what the medieval builders could not have known: the soft, waterlogged soil beneath the foundation needed decades to compress under the existing weight before it could bear the weight of additional floors. If construction had proceeded continuously, the tower would almost certainly have collapsed before it was finished. The wars with Genoa, Lucca, and Florence that repeatedly interrupted construction — events entirely unrelated to any decision about the tower — were the mechanism that preserved it.
This is not the story most people know about the Leaning Tower of Pisa. The story most people know is: it leans because of soft soil, Galileo dropped cannonballs from it to demonstrate the principle of gravitational acceleration, and in the 1990s engineers stabilized it.
The soft soil part is accurate. The Galileo story is almost certainly a legend invented by his disciple twelve years after Galileo's death, published 75 years after the supposed event, with no contemporary corroboration and no mention in Galileo's own writings. And the 1990s stabilization — which is presented as a triumph of modern engineering — nearly caused the catastrophic collapse it was designed to prevent, when a soil-freezing attempt in 1995 caused the tower to lurch more in a few days than it had in the previous year.
