The Planning of Pearl Harbor

On this date in 1941, the Imperial Japanese Navy launched an incredibly daring, technically sophisticated combined naval-aerial surprise attack on the U.S. naval base at Pearl Harbor, just northwest of Honolulu on the Hawaiian island of Oahu. The devastating aerial attack carried out by Japanese fighters, dive-bombers and torpedo planes crippled the U.S. Pacific fleet as a preamble to Imperial Japan’s lunge for strategic territories spanning the Pacific Ocean – but it also stirred the wrath of the American people, decisively ending U.S. isolationism and bringing the world’s largest industrial power squarely into the war against Japan and its European allies in Nazi Germany and Fascist Italy.

The Economic Vise

Pearl Harbor was born of strategic desperation. Over the previous couple years, Japan and the U.S. had been engaged in a tit-for-tat diplomatic and economic struggle, as the Roosevelt administration tried to restrain escalating Japanese aggression with embargoes on raw materials crucial for the Japanese war machine. Japan was heavily dependent on American supplies of oil and metal, with American shipments accounting for 80% of Japan’s oil and copper imports and almost half of its scrap iron imports.

Over several years the U.S. tightened the economic vise, responding to Japanese aggression in China and Southeast Asia by cutting off supplies of aircraft materials in 1939, scrap steel in 1940, and machine tools and metal ore in 1941. The final blow came with the suspension of oil deliveries in summer 1941.

At first, the Japanese hoped to negotiate their way out of the American economic embargo, but the Americans’ unwavering opposition to Japanese foreign policy convinced the Japanese leadership that further negotiation would be fruitless. They decided instead to deliver a knockout blow to the U.S. Pacific fleet with a surprise attack on Pearl Harbor, which would, they calculated, give Japan two years of unchallenged supremacy in the Pacific and a window in which they could conquer the oil-rich Dutch East Indies (today Indonesia) and the rubber plantations of Malaya. This, in turn, would give Japan enough resources to fight on once the U.S. rebuilt its Pacific fleet.

The odds were steep, to say the least. The plan required bringing a huge aircraft carrier battle fleet – comprised of six carriers, two battleships, and 48 combat and support vessels including cruisers, destroyers, submarines and tankers – 4,000 miles from the northeast coast of Japan to Pacific waters north of Hawaii in complete radio silence, a feat akin to smuggling an elephant through airport security. Ships in the attack fleet couldn’t communicate with home base, meaning there was no way to call off the attack without exposing their position.

Uphill Battle

In fact, the man in charge of planning the attack – the brilliant admiral Isoroku Yamamato, who had studied in the U.S. and respected American fighting spirit – advised against it, noting that even if it succeeded, Japan would still face an implacable enemy drawing on huge resources. He famously warned:

“Should hostilities once break out between Japan and the United States, it would not be enough that we take Guam and the Philippines, nor even Hawaii and San Francisco. To make victory certain, we would have to march into Washington and dictate the terms of peace in the White House. I wonder if our politicians (who speak so lightly of a Japanese-American war) have confidence as to the final outcome and are prepared to make the necessary sacrifices.”

But the hyper-nationalists in charge of Japan could not imagine submitting to what they perceived as American bullying, and decided on war, no matter how desperate, and no matter how steep the price. The die was cast.

After leaving Japan on November 26, the Japanese fleet steamed east across the Pacific, reaching a point about a thousand miles north of Hawaii on December 3. During their silent run, the Japanese ships were scattered by a sudden Pacific storm that lasted two days, stringing them out over hundreds miles of open water – but still managed to regroup with minimal use of short-range, low-power radio to communicate their positions, a remarkable feat of seamanship and navigation. Then from December 4-6, the fleet headed south until it reached a staging point a few hundred miles north of Oahu in the early morning hours of December 7.

Here the attack shifted from its naval phase to the aerial phase, with two waves of dive-bombers, fighters, and torpedo planes taking off from the carriers beginning at 6:10 a.m. Hawaii time. The first bombs fell at 7:48 a.m. Surprise was complete, as the operators of the primitive American radar mistook the approaching Japanese planes for a returning flight of U.S. B-17s.

Assisted by some ineffectual midget submarines, over two hours and 20 minutes 354 Japanese planes sank four American battleships, damaged three more and caused the last to run aground, while damaging or destroying ten other ships and over three hundred aircraft. The human toll came to 2,402 killed and 1,247 wounded, including 1,177 dead aboard the U.S.S. Arizona, the hardest-hit. Japanese losses were light, reflecting their success in achieving total surprise. Meanwhile Japanese forces fanned out across the Pacific, with near-simultaneous attacks on American forces in the Philippines and Guam, and tiny colonial garrisons in the Dutch East Indies and Malaya.

Although the attack was devastatingly successful, it was not the knockout blow Japanese planners had intended. Most importantly, the U.S. Navy’s Pacific carrier fleet was left untouched, since all three aircraft carriers were at sea during the attack. These would provide a crucial counterbalance to Japanese naval power in the Pacific in 1942, beginning with the stunning American victory at the battle of Midway.

Worse, the Japanese leadership badly miscalculated in their long-term strategy. In particular, they were over-optimistic about their ability to secure the long maritime supply lines from the oil wells of the East Indies to Japan; these proved vulnerable to American submarines, which helped strangle the Japanese economy in the final years of the war.

Last but not least, the effect on American morale was essentially the opposite of what the Japanese hoped. In the weeks following Pearl Harbor (which included Adolf Hitler’s declaration of war on the U.S. on December 11), approximately one million American men volunteered for military duty. This would be followed by a draft that eventually built the American military into 12-million-strong juggernaut by 1944, compared with Japan’s 4.3 million men in military service by the end of the war.

13 Incredible Facts About Frederick Douglass

The list of Frederick Douglass's accomplishments is astonishing—respected orator, famous writer, abolitionist, civil rights leader, presidential consultant—even more so when you consider that he was a former slave with no formal education. In honor of his 201st birthday, here are 13 incredible facts about the life of Frederick Douglass.

1. He bartered bread for knowledge.

Because Douglass was a slave, he wasn't allowed to learn to read or write. A wife of a Baltimore slave owner did teach him the alphabet when he was around 12, but she stopped after her husband interfered. Young Douglass took matters into his own hands, cleverly fitting in a reading lesson whenever he was on the street running errands for his owner. As he detailed in his autobiography, Narrative of the Life of Frederick Douglass, he'd carry a book with him while out and about and trade small pieces of bread to the white kids in his neighborhood, asking them to help him learn to read the book in exchange.

2. He credited a schoolbook with shaping his views on human rights.

During his youth, Douglass obtained a copy of The Columbian Orator, a collection of essays, dialogues, and speeches on a range of subjects, including slavery. Published in 1797, the Orator was required reading for most schoolchildren in the 1800s and featured 84 selections from authors like Cicero and Milton. Abraham Lincoln was also influenced by the collection when he was first starting in politics.

3. He taught other slaves to read.

While he was hired out to a farmer named William Freeland, a teenaged Douglass taught fellow slaves to read the New Testament—but a mob of locals soon broke up the classes. Undeterred, Douglas began the classes again, sometimes teaching as many as 40 people.

4. His first wife helped him escape from slavery.

Anna Murray was an independent laundress in Baltimore and met Douglass at some point in the mid-1830s. Together they hatched a plan, and one night in 1838, Douglass took a northbound train clothed in a sailor's uniform procured by Anna, with money from her savings in his pocket alongside papers from a sailor friend. About 24 hours later, he arrived in Manhattan a free man. Anna soon joined him, and they married on September 15, 1838.

5. He called out his former owner.

In an 1848 open letter in the newspaper he owned and published, The North Star, Douglass wrote passionately about the evils of slavery to his former owner, Thomas Auld, saying "I am your fellow man, but not your slave." He also inquired after his family members who were still enslaved a decade after his escape.

6. He took his name from a poem.

He was born Frederick Augustus Washington Bailey, but after escaping slavery, Douglass used assumed names to avoid detection. Arriving in New Bedford, Massachusetts, Douglass, then using the surname "Johnson," felt there were too many other Johnsons in the area to distinguish himself. He asked his host (ironically named Nathan Johnson) to suggest a new name, and Mr. Johnson came up with Douglas, a character in Sir Walter Scott's poem The Lady of the Lake.

7. He was deemed the 19th century's most photographed American.

There are 160 separate portraits of Douglass, more than Abraham Lincoln or Walt Whitman, two other heroes of the 19th century. Douglass wrote extensively on the subject during the Civil War, calling photography a "democratic art" that could finally represent black people as humans rather than "things." He gave his portraits away at talks and lectures, hoping his image could change the common perceptions of black men.

8. He refused to celebrate Independence Day.

Douglass was well-known as a powerful orator, and his July 5, 1852 speech to a group of hundreds of abolitionists in Rochester, New York, is considered a masterwork. Entitled "What to the Slave is the Fourth of July," the speech ridiculed the audience for inviting a former slave to speak at a celebration of the country who enslaved him. "This Fourth [of] July is yours, not mine," he famously said to those in attendance. "Do you mean, citizens, to mock me, by asking me to speak to-day?" Douglass refused to celebrate the holiday until all slaves were emancipated and laws like the Compromise of 1850, which required citizens (including northerners) to return runaway slaves to their owners, were negated.

9. He recruited black soldiers for the Civil War.

The Union attack on Fort Wagner, Charleston, during the American Civil War. The fort was under attack from July 18 to September 7, 1863, by soldiers including the 54th Massachusetts Volunteer Infantry, the first African-American regiment in the U.S. Army.

Douglass was a famous abolitionist by the time the war began in 1861. He actively petitioned President Lincoln to allow black troops in the Union army, writing in his newspaper: "Let the slaves and free colored people be called into service, and formed into a liberating army, to march into the South and raise the banner of Emancipation among the slaves." After Lincoln signed the Emancipation Proclamation, Douglass worked tirelessly to enlist black soldiers, and two of his sons would join the 54th Massachusetts Regiment, famous for its contributions in the brutal battle of Fort Wagner.

10. He served under five presidents.

Later in life, Douglass became more of a statesman, serving in highly appointed federal positions, including U.S. Marshal for D.C., Recorder of Deeds for D.C., and Minister Resident and Consul General to Haiti. Rutherford B. Hayes was the first to appoint Douglass to a position in 1877, and Presidents Garfield, Arthur, Cleveland, and Benjamin Harrison each sought his counsel in various positions as well.

11. He was nominated for Vice President of the United States.

As part of the Equal Rights Party ticket in 1872, Douglass was nominated as a VP candidate, with Victoria Woodhull as the Presidential candidate. (Woodhull was the first-ever female presidential candidate, which is why Hillary Clinton was called "the first female presidential candidate from a major party" during the 2016 election.) However, the nomination was made without his consent, and Douglass never acknowledged it (and Woodhull's candidacy itself is controversial because she wouldn't have been old enough to be president on Inauguration Day). Also, though he was never a presidential candidate, he did receive one vote at each of two nomination conventions.

12. His second marriage caused controversy.

Two years after his first wife, Anna, died of a stroke in 1882, Douglass married Helen Pitts, a white abolitionist and feminist who was 20 years younger than him. Even though she was the daughter of an abolitionist, Pitts's family (which had ancestral ties directly to the Mayflower) disapproved and disowned her—showing just how taboo interracial marriage was at the time. The black community also questioned why their most prominent spokesperson chose to marry a white woman, regardless of her politics. But despite the public's and their families' reaction, the Douglasses had a happy marriage and were together until his death in 1895 of a heart attack.

13. After early success, his Narrative went out of print.

Narrative of the Life of Frederick Douglass, An American Slave, Written by Himself, his seminal autobiography, was heralded a success when it came out in 1845, with some estimating that 5000 copies sold in the first few months; the book was also popular in Ireland and Britain. But post-Civil War, as the country moved toward reconciliation and slave narratives fell out favor, the book went out of print. The first modern publication appeared in 1960—during another important era for the fight for civil rights. It is now available for free online.

Belgium's Blue Forest is One of the Most Beautiful Natural Areas on Earth

Imagine if the poppy fields in The Wizard of Oz were all blue—and real. That's how Belgium's Hallerbos forest looks for a short time each spring. For roughly 10 days in April or May, innumerable bluebells blossom, covering the forest's floor in a lovely violet.

Dutch for "Halle's forest," Hallerbos is located about 30 minutes outside of Brussels. But while the forest is currently part of the Belgian state, its ownership has varied, starting with its first known owner in the 7th century. Records list it as having been part of the expansive land of the Abbey of St. Waltrudis, in Mons (about an hour south of the forest). A few centuries later, it became part of the duchy of Arenberg before passing to the French Republic after their troops invaded in 1794, then to the Netherlands in 1815, and eventually returning to the Duke of Arenberg in 1831.

Unfortunately, when World War I hit Europe, the German army felled much of the forest for wood, diminishing its original size of 1125 hectares down to 569 hectares (or roughly 1400 acres). Belgium regained control of the Hallerbos forest in 1929 and spent the next 20 years actively reforesting the land. This extensive history is what, in part, makes the forest look the way it is today—because though the trees are relatively new, the bluebells are ancient.

In fact, an abundance of bluebells is an indicator of the age of a forest. Certain types of flowers, including the small, white wood anemones and pale yellow native primroses, are very often markers of ancient woodlands—this flora grows deep underground and doesn't spread through trafficked or harvested land, meaning that that larger groves of them tend to only be found in secluded areas. And for bluebells (also called wood hyacinth or wild hyacinth), their life cycle is dependent on brisk weather and sunshine, so they sprout and bloom before the trees above them have fully budded. Then, as quickly as they came, they turn to seed and continue growing their roots deeper to survive another year.

And thus, the extraordinary sight of a blanket of bluebells scattered through the forest is best observed during the early spring. Of course, this effect makes for some absolutely gorgeous photographs, so it's no wonder that visitors flock to the woods each year. Hallerbos provides directions to the forest by both car and public transportation, as well as two different maps for walks through the growth and a bloom tracker to plan for the prettiest possible visit.
