Upon its completion, the fleet was larger and more powerful than all the combined fleets of Europe during the age of explorers. It consisted of Fuchuan warships, patrol boats, supply ships, troop transporters, water tankers, and, largest of all, the treasure ships. These colossal vessels were a marvel in engineering. They were more than 120 meters long. (That’s longer than a football field.) And, in order to ensure that the ships would still be maneuverable, they were built with a shallow hull. This hull was wide and contained sixteen watertight bulkheads. The use of watertight bulkheads was not perfected in Europe until the nineteenth century.
In addition to being large, the treasure ships had a carrying capacity of 3,600 tons. Two anchors were used to weigh the ship in harbor. Each one measured more than two meters long. Rudders, which could be as long as eleven meters, steered the ship on its journey. So the sailors could make the best use of the wind, craftsmen designed triangular-shaped sails that pivoted around the masts. In the case of the treasure ships, there could be as many as nine masts. Unlike later European ships, Zheng He’s vessels did not lose proficiency if the wind was not at their backs.
Another unique feature of the Chinese fleet was that it was completely self-sufficient. Tankers supplied much-needed water, while cattle ships kept the crews in beef. Poor diet often posed problems for crews. Without vitamin C-enriched foods, crew members suffered from scurvy. Zheng He came up with a solution to the problem. Certain supply ships came equipped with growing beds, which the crews used to raise soy. Not only is soy rich in vitamin C; it also yields a big crop in a small amount of space. Because of the constant supply of sprouts, crew members no longer fell prey to the agonizing effects of scurvy. Zheng He managed to solve the age-old affliction of seafarers, which would continue to plague European sailors until the voyages of Captain Cook some three and a half centuries later.
The fleet itself consisted of 300 ships and 28,000 crew members. Although the ships were large enough to house settlers, the emperor had no interest in colonization. He wanted trade. In particular, the Chinese wanted pepper and frankincense. In exchange for these goods, they offered silk and porcelain. The Silk Road had been closed to them by the Mongols, so the Chinese became masters of the waterways. They raised money for their expeditions by intimidating countries into paying tribute. Most did not refuse because of the great size of the navy. When countries did offer objections, they were met with force and easily defeated by the well-equipped Chinese ships, which used cannons, flame throwers, grenade launchers, water mines, and crossbows that could fire twenty arrows every fifteen seconds. This immense strength coupled with Zheng He’s own diplomatic skill ensured his place as king of the high seas. Zheng He used his powerful position for other things besides trade. He brought back medical cures from the Arabic world as well as exotic animals; the most important of these being the Arabian horse, which proved more maneuverable than the Chinese horse.
Despite the improvements made to society, conservative followers of the teachings of Confucius felt that the navy was becoming too costly. They also believed that tradition was far more important and better for the country than trying to attain knowledge from the outside world. These beliefs spread throughout court. The imperial court split into two separate factions; the traditionalists who wanted isolation and those who wanted all the world could provide. The matter soon settled itself.
In 1424 Emperor Zhu Di died. Conservatives wasted no time seizing control of the throne. The new emperor immediately implemented changes that would ensure China’s centralization. He ordered that all naval voyages to the outside world cease. He also stopped all construction of naval vessels. None were to be built or repaired. Before long, the ships fell into disrepair. By 1503 the navy was one-tenth its former size. Conservatives destroyed the ship logs and any other evidence they could find of the navy’s voyages.
Zheng He did not wish for his greatest work to die without recognition. He erected a monument in honor of the goddess who he claimed protected him during his perilous journeys. Along with praises and exaltation, the monument included detailed accounts of where the navy had traveled. According to the writings, the navy sailed to Sumatra, Taiwan, Java, Ceylon, India, Persia, the Persian Gulf, Arabia, the Red Sea, and the African east coast. There is also modern evidence suggesting that the Chinese navy made it all the way to the Americas.
If this is true, then the Chinese could have easily gone on to be the world’s first superpower. With a strong naval presence in China, it is doubtful that the Portuguese would have established ports on the Chinese coast. The same is true for the rest of the Europeans. They may never have branched out as far as they did had the Chinese already established themselves firmly in India and the Persian Gulf. Centuries later, Japan would have thought twice before invading such a powerful nation. These are mere speculations and it is difficult to gauge what might have happened had the Chinese maintained a strong naval presence. However, one thing is certain: A country that once looked outward and led the world through technology and exploration turned in on itself, leaving only hints of its former glory.

FALSE SAVINGS
Point-Blank
1452
In 1452, Constantine XI Palaeologus ruled over a Byzantine empire that consisted of no more than a few small islands and the city of Constantinople itself. The city at that time was no more than a feeble image of the great imperial capital it once had been. The population had dwindled from more than 1 million residents to about 50,000. The army that could once field tens of thousands of fully armored cavalry now consisted of fewer than 7,000 men, including mercenaries.
What did remain unchanged were Constantinople’s massive walls. The entire city was surrounded by at least one thick and high wall, even where the city directly adjoined the water. On its more vulnerable eastern side, Constantinople was defended by double walls with a smaller outer wall six feet thick and twenty-five feet high and an inner wall, or great wall, that was more than twenty feet thick and forty feet high. There was a thirty-foot-deep ditch between these walls. A road ran inside each wall to allow quick and sheltered movement, and only small gates allowed access between them. Most of the gates were on the eastern wall and even more formidable than the wall itself.
Mohammed II ruled a Turkish empire that controlled all of the Mideast and parts of Africa. He wanted to expand his control into Europe, but, as it had for more than a thousand years, Constantinople blocked the way. He gathered an army and built a fort to cover his crossing into Europe near the city. There was no question of his intentions and no way for Constantine XI and his city to avoid a siege.
The defenses of Constantinople
Constantine put out a call for help to all of Christendom. He got very little response. The kings of France and England sent nothing. The pope demanded the Eastern Church recognize his authority. It was a bitter demand for the other center of Christian faith; even so, the Byzantine emperor agreed. When he did, the pope sent only 200 bowmen. The only real reinforcement that arrived in time was a mercenary who was an expert in defending walls. The mercenary brought with him 700 skilled soldiers. But men trickled in until, by the end of the year, the city’s garrison had risen to 10,000. Across the straits, Mohammed II waited with almost 100,000 men, and more were being mobilized in various parts of his vast empire.
One other mercenary group answered the Byzantine ruler’s call for help. In 1452 gunpowder weapons were just beginning to change warfare forever. Artillery was large, temperamental, and dangerous to fire. Gunners often made their own gunpowder and just as often cast their own cannon as well. The men who operated the cannons were civilian specialists who were paid highly because of the risk and the skills required. Among the greatest of the mercenary cannoneers of this time was Urban of Hungary. Hungary was a Christian kingdom, so before the siege began, Urban offered himself, his cannons, and his men to Constantine XI. Those cannon ranged from small guns that fired a metal or stone ball less than a few pounds, to one named
“Bassilica” that could fire only seven times per day but threw a ball that weighed upward of 600 pounds. Now, if the strength of Constantinople was in its wall, you might think that its ruler would understand that the cannons would pose the biggest threat to the walls. But Constantine XI decided the mercenary gunners and their guns were too expensive to hire. Even though there was a good chance that Urban would offer his cannon to Mohammed, for reasons of his own, Constantine turned them away. He passed completely on hiring Urban of Hungary and his troop of mercenary cannoneers. Within a few months, Mohammed II had hired Urban’s troops, and Bassilica, to assist him in attacking Constantinople. Having given the Byzantines first chance, the gunner accepted the sultan’s offer. Instead of defending the Christian city, his guns would instead batter down its walls.
By the end of the spring of 1452, the Turks had completed the fort that was to cover their army while they crossed the Bosphorus. By spring of 1453, Mohammed II was ready to besiege Constantinople. On April 6, every gun in the Muslim army began pummeling the city’s walls. Most of these were those cannons hired from Urban the Hungarian. After twelve days of steady bombardment, there was a narrow breach in one wall. Walls that had held out for a millennium were breached in less than two weeks by the cannon that Constantine XI had turned down. Hundreds of Turks attacked the small breach but were easily beaten off.
On May 6, the cannons created another breach where the Lycus River entered the city through the eastern wall. On the next day, the sultan threw 25,000 men into the attack, which was driven off after only three hours of intense fighting. The garrison did their best to repair the damage, but from this point they were stretched by the need to always keep men near the weakened areas.
Six days later, another breach was opened near the northern end of Constantinople’s great wall. The attack on that breach almost broke into the city. Only the timely reinforcement of the defenders by Constantine and his imperial guard saved Constantinople. The siege continued for weeks, with the valiant defenders thwarting an attempt to use a giant siege tower and tunnels to overcome the defenses. All this time, the cannon battered at the walls, attempting to create new breaches and reopen those that had been repaired. Ultimately, even the thick great wall was torn and battered.
After his largest siege tower was lost, some of the sultan’s generals began to council him to withdraw. But others encouraged the Turkish leader to give it one more try. If the general assault failed, they would withdraw. The cannon that Constantine XI had previously turned down had seriously weakened the great wall where the Lycus River entered the city. On May 29, Mohammed II threw everything into one final assault. Almost 20,000 Bashi-Bazouks, mercenaries who fought for loot, attacked first. They were driven off, but directly behind them came a second line of Turkish regulars who took up the attack on the weakened wall. They pushed at the partially blocked breaches and were driven off after only two hours of intense fighting. The defenders were exhausted and the great wall provided less and less protection. But before they could recover, a third wave of Turks attacked. Summoning their last reserves, the Christian defenders drove them away as well.
Unfortunately for the city, while almost every soldier was fighting near the Lycus breach in the center of the great wall, a few Turkish soldiers managed to rush through a small gate that had been left open elsewhere. They seized control of a small tower at the far north end of the wall and raised the sultan’s banner over it. While this really was just a minor threat, it appeared to be a disaster to the wall’s defenders. Their morale and determination plummeted as word spread among the defenders. Then the leader of the largest group of mercenaries was wounded and had to be carried from the wall. Exhausted men who had been fighting on adrenaline lost hope.
The sultan sent in his own elite troops, the Janissaries, who managed to gain control of the section of the eastern great wall from the Lycus to the next gate above it, the Adrianople Gate. Once the Janissaries had that gate open, tens of thousands of Turkish soldiers poured into Constantinople. Constantine XI Palaeologus, the last Byzantine emperor, died fighting in the streets.
The Turkish victory almost didn’t occur. Under pressure from his generals, if the last attack had failed, Mohammed II was ready to pack up and leave. Had the Byzantine emperor hired Urban the Hungarian and his cannon, the breaches that weakened the great wall would have never happened. Without those breaches, the sultan’s army would have found assaulting the walls of Byzantium an almost impossible task.
The effect of the fall of Constantinople on Europe was a surprising one. The subsequent monopoly prices charged by the Turkish merchants for the products and spices of the East inspired western Europe to search for another way to trade with the Orient. Within thirty years the Portuguese were traveling around Africa, and exactly forty years later, Ferdinand and Isabella financed Christopher Columbus’ first expedition. The fall of the city forced the beginning of the greatest period of exploration ever recorded. While Constantine XI’s mistake of not hiring Urban doomed Constantinople and brought about the end of the Byzantine empire, that same loss led to the great Age of Exploration.

SOME MISTAKES HAVE TURNED OUT WELL
A Math Error
1492
In 1491, a noted Spanish ship’s captain and seaman made a math error when calculating the circumference of the earth. At the equator, a line drawn all the way around our planet is about 25,000 miles long. This has been known and verified by various forms of mathematics since the time of ancient Egypt. But Christopher Columbus was convinced based on his own calculations that this number was 15,000 miles. That is a 10,000-mile difference and the reason he was sure he could reach China by sailing westward from Spain. If he had been correct, it would have been an easy sail. The error appears to have come from Columbus using the wrong value for a degree of longitude when looking at Chinese maps. It is even possible he used the distances as shown on Ptolemy’s maps, which were also far off.
At this time, the rivalry between Portugal, who had a painfully long but known route to the Orient around Africa, and Spain was intense. The Spanish monarchs were willing to do just about anything to find their own entry into the incredibly profitable trade. Many of us have heard the tale of Columbus convincing Queen Isabella that the earth was round by using an orange. There is no chance that really happened as just about every educated person in Europe already knew it was round. Columbus’ math error explains why the advisers to Ferdinand and Isabella all opposed financing his expedition. It wasn’t because they thought the earth was flat; it was because they had checked the sailor’s calculations. The learned men of Spain’s greatest court opposed financing the explorer because they had determined his math was wrong . . . and it was.
Even so, the Spanish monarchs decided to take a chance and in 1492 supplied three rather small ships to the mathematically challenged seaman. Or maybe it seemed a cheap way to just get rid of him after he had lobbied them for months on end. And so the rest is, as we say, history. Columbus sailed in the Nina, Pinta, and Santa Maria. Eventually, and rather heroically, he discovered the New World. Or at least he found a few islands in the Caribbean. The real importance of this being that Columbus showed everyone that something was there.
Incidentally, Columbus made another mistake while on his journeys. But this one was more fun. He mistook manatees for mermaids and recorded the finned women’s presence in the newly found waters.
Believing his own math was vindicated, the captain called the native peoples “Indians” and called the islands he finally landed on the “Indies.” Columbus died poor and would be amazed at how he has been revered today. He also might be a little upset to find out just how wrong he was. This math error may have been for Spain and Europe the most serendipitous mistake of all time. It brought the Spanish crown two centuries of plundered wealth and power while opening two continents to Europe.

OFF COURSE
Oh Yeah,
and a New Continent
&
nbsp; 1500
The Portuguese spice trade route to the Orient was the glory and the secret of that small nation. They had found a path, albeit a long one, that bypassed the Islamic merchants. The route they took was to sail around Africa and then up the eastern African coast before sailing across to India. Navigation was primitive, and techniques for preserving food were not much better. Spending any time in the open waters could get a ship lost and doom the crew to a death of thirst or starvation. Most merchants in the fifteenth century tried to always stay in sight of land. The long trip was risky, but immensely profitable. If one ship in ten returned full of spices, the profits were enough to cover the cost of the lost ships and give the investors 1000 percent return on their money.
In 1500, a Portuguese merchant named Pedro Alvares Cabral led his own fleet of fifteen ships attempting to trace the route of Vasco da Gama to India. But rounding the horn of West Africa, his ships caught some unusual winds and were pushed away from the coast. This likely caused everyone on board a good deal of concern. He sailed south and ran into an unfamiliar coastline. Cabral knew it was not part of Africa because it was on the wrong side of the ocean. It was to his west, and since he was supposed to be sailing down the coast of Africa, that would be to his east. It was a strange and wild land covered mostly by jungle. Today we call the country he found Brazil. Cabral had other business: He was after spices, not new continents. So after sailing along its coast for ten days and claiming the new land in the name of his king, Manuel I, (more or less standard procedure in his time), the Portuguese admiral wrote up a report and sailed east until he found a coast that was on the correct side of the ocean. Cabral finally did reach India, and four of his ships made it back to Portugal more than a year later.
