On a serious note, though, this is sometimes bred into men culturally (and in the case of the Kelts, the women, too). Japanese members of the Bushi class were obliged by Bushido to never show their fear. They weren't so callow as to deny that they felt fear, but it was considered honorable to overcome it. A man steeped in that tradition would be so shamed by having displayed cowardice that he would likely commit seppuku--put a knife in his own guts. A man captured in battle who felt storngly enough attached to his own commander would insist on being allowed to commit seppuku, and the request would be honored. (Members of the Bushi class, those we call Samurai, would lose respect for their commander if he did not grant such a request.) In honor of his resolution, a friend or other companion would be allowed to stand behind him with a katana, and after he had plunged the knife into his own guts, the friend would then cut off his head to end his suffering. The "banzai" charges of Japanese infantry during the Second World War were an example of this cultural value, as were the Kami-kazi pilots. (Kami-kazi means "divine wind." When the Mongols from China threatend to invade Japan, their fleet was destroyed by a typhoon. The Japanese considered that to have been a spirit wind, or a divine wind, a great
kami, i.e., spirit, which protected their divine land.) In the Second World War, the entire paraphernalia of ritual suicide would be observed by kami-kazi pilots before they took off. They would write a death poem, a copy to be sent to their family, and the text copied for publication. They would put the poem in a sash wrapped around their uniform, along with prayers by those who were Buddhists. They would wrap a bandana around their heads with patriotic slogans written on it and the red "meat ball" (as the Americans called it), the symbol of Nippon, in the center. They would be ritually served saki before getting in their aircraft, and the ground crews would stand at attention to honor them as they took off.
This is to be seen in other cultures, too. Among the Norge (i.e. the Norwegians, the Norse), the Danes and the Goths (i.e., the Swedes), but most expecially the Norge, there were the berserkers. The word means "bear shirt," and referred to them dressing in a bear skin cloak before entering battle, and rather than wearing armor. These were sometimes also called Ulfhethnar, meaning wolf skin, another adornment they would wear into battle. Some claim that the Berserkers were so called because they were required to go into the woods unarmored with nothing but a knife, to kill and skin a bear--but this is not reliably attested.
The Scandanavians and the North Germans (such as the Saxons) fought in a style which became a doctrinal imperative, because really, with the weapons they used (they used no missile weapons and no heavy cavalry, and this method could probably stop an attack of heavy cavalry--the Saxons at Hastings held off repeated charges of the Norman heavy cavalry, and the line only broke when King Harold was killed). This tactical doctrine was the shield wall. The two sides would line up in parallel order, both sides facing one another, and they would join their shields (many had hooks so that they could be locked together, although that could dangerous if a man fell), and then the two sides would slug it out. As a man fell, the shield wall would close the gap, and the slugfest would continue. It was such a ritualized combat, often involving no more than a few hundred men on a side, or even just a few dozen, that if a man broke and ran from the shield wall, the other side would desist long enough for his companions to run him down, take his sword away and kill him. (Any man killed in combat who died without his sword or axe in his hand could not enter Valhalla.) Then they would resume the battle of attrition. The combat would usually only finally end when one side had inflicted enough casualties on the other that they could lap around the flanks of their enemies, at which time the shield wall could be broken by sheer weight of numbers. At that point, the losing side could surrender at discretion with no loss of honor. Many, perhaps even most, though, would elect to continue fighting, and if they fell, dropping their weapon, their enemies would put their sword in their hand before administering the
coup de grace, to honor their courage. Many devices were thought up to hasten the breaking of the shield wall, such as the introduction of the battle axe, but the technique remained in use until as late as the battle of Hastings (1066) and probably longer in small local quarrels. You could **** yourself, but if you held your place in the shield wall, even your bitterest enemies would honor your courage. This is a different, much more focused kind of courage than the gameness you describe--battles with large forces of thousands of men could go on all day. It would take a special kind of courage to stick to the work when your arm is so tired you feel you can hardly lift your sword.
The berserkers were intended as another method to break the shield wall. They were intendced to run screaming at the enemy, weilding a huge sword or battle axe, wearing no armor and carrying no shield and sacrificing their lives to break the enemies shield wall. It was not necessarily a reliable technique, though. Three weeks before the battle of Hastings, King Harold marched north to what is now Yorkshire, and at Stamford Bridge, defeated Harald Hadrada, a Norge who also claimed his throne. Harald is said to have had 2000 berserkers--however many there were, they utterly failed to break the Saxon shield wall, they were all impaled on Saxon spears or cut down as they closed with the line.
"Mere" discipline can achieve the same effect. When Rome was a rising power, and threatened to conquer all of what is now Italy, the Greek colony cities of the south, in the region known as Italia (hence the name Italy), hired Pyrrhus, the King of Epirus and Macedon, to defeat the Romans. This he routinely did, but at such a cost that he was eventually ruined. Marching on Rome, he was unable to take the city, and began to march back south. At the battle of Asculum, he very nearly destroyed a consular army, killing at least 6000 Romans. But it cost him the cream of his own army. It is said (i cannot state it is known) that after the battle, he looked on the Roman dead, all lying in their ranks, facing their enemy, and wept, because he knew his army was ruined, and that he'd never command another such army. It was the discipline of the Romans which lead very nearly every man of two legions to die where they stood and fought. The only survivors were those wounded who had been carried off before the lines were joined, and the detachments of flank guards who retreated in good order. This is the origin of the term a Pyrrhic victory, a victory which comes at such a cost as to undo the victor. Plutarch wrote:
Quote:The armies separated; and, it is said, Pyrrhus replied to one that gave him joy of his victory that one more such victory would utterly undo him. For he had lost a great part of the forces he brought with him, and almost all his particular friends and principal commanders; there were no others there to make recruits, and he found the confederates in Italia backward. On the other hand, as from a fountain continually flowing out of the city, the Roman camp was quickly and plentifully filled up with fresh men, not at all abating in courage for the loss they sustained, but even from their very anger gaining new force and resolution to go on with the war.
This sort of courage, the courage of a high order of discipline, allowed the Romans to march over the corpses of their enemies for a thousand years.
Perhaps this is not what you meant, perhaps you meant the attitude of the individual. Consider this a description of the corporate version.
