Grace's constellation house

In 2525, man went to war with the interstellar alliance on fertile planet. Zhiyuan is the gateway to the earth and the headquarters of UNSC. In 2552, the earth fell and was in jeopardy.

2 160-2200: Early conflict

The human history of this period is full of a series of bloody conflicts between the major governments and factions in the solar system. Conflicts of great historical significance include: the satellite battle of Jupiter, the rainforest war and a series of encounters with Mars.

With the aggravation of overpopulation and political turmoil on the earth, many new political movements have emerged. The most famous political heresy movements in this period were "Coslov Doctrine" and "Freeden" movements. "Kos Loweck" refers to the supporters of Folad Coslov, a powerful leader of the new communists. They are committed to returning to the hope and glory of communism and eliminating the harmful influence of companies and capitalists, especially in low-earth orbit and alien colonies.

Freeden Movement is the revival of fascism, which originated from the anti-Koth Loweck sentiment and rooted in Jupiter colony (largely supported by enterprises in the Federal Republic of Germany, which often became the object of Koth Loweck's "workers' uprising"). "Frieden" literally means "peace"-that is to say, they believe that peace can only be achieved if "tyrants on land" are eliminated.

9.22160 March-June: the battle of Io begins.

Jupiter's separatist forces attacked the United Nations colonial adviser on Io, resulting in a fierce battle between the Earth Army and Jupiter's "Freeden" forces for three months. Although this is not the first armed conflict in our solar system, it has become one of the bloodiest battles and is widely regarded as the fuse of the next wave of friction and militarism.

The battle of Io also escalated the tension between governments on earth-many countries established colonies in the solar system and began to compete for their own interests outside the earth. The continuation of the colonial war made the tension on the earth explosive, which triggered several armed conflicts on the earth.

9.3 2 162: rainforest hegemony

Armed conflicts swept across the South American continent, and Koth Lauwick, Frieden and the United Nations Army went to war because of different ideologies. This, in turn, exacerbates conflicts outside the earth.

9.421631February: Fighting on Mars

The three main factions on the earth ignited the war burning to Mars in the rainforest hegemony. A series of blitzkrieg against Koth Lauwick's army near Argyre Planitia on Mars is the first deployment of non-ground troops. The battle won a decisive victory. Therefore, the later military guidance strategy used to be a large-scale ground force raid to cooperate with the ship landing operation.

9.5 2 164: Star Wars

The United Nations forces began to form a large-scale assembly pattern, and finally ushered in the first real star war. After the successful deployment of Mars troops, the large-scale recruitment and propaganda strategy greatly boosted the morale of UNSC (United Nations Space Command) troops. The United Nations forces defeated the forces of Koth Loweck and Freeden on the earth, and then began to systematically concentrate on expelling the remaining forces established on other planets in the solar system. After these local wars, the armies of Freeden and Kos Loweck were completely wiped out by the huge, unified and powerful United Nations forces.

9.6 2 170: expansion

2/KLOC-The war in the 1960s prompted people to establish a unified government on the earth. Now, the winner must deal with less obvious but equally serious threats: overpopulation and a huge army that surrendered without a fight.

In the years after the war, a large number of people expanded rapidly; The resource destruction and famine left by the hegemony of the rainforest are even worse, and the world economy is in jeopardy.

9.7 229 1: Beyond the speed of light

A team of researchers, physicists and mathematicians is secretly developing Shaw-Fujikawa Translight Engine (SFTE), which is a special means to drive spacecraft through distant stars.

This new engine allows spacecraft to drill into "slipstream" or "slipspace", also known as "migration fault space". "Fault" is a space under the law of elastic physics, which allows faster-than-light travel and avoids the side effects of relativity. Faster than light travel is not instantaneous; "Short-distance" jumps usually take two months, while "long-distance" jumps can last six months or more.

SFTE can produce resonance field, and combined with the physical characteristics of transition space, it can greatly shorten the time of cross star space; However, scientists have also noticed that there will be a strange temporary current "variable" inside the jump space. Although human scientists are not sure why the time required for interstellar travel is not a constant, there is a theory that there is a "vortex" or "surge" inside the jumping space-which leads to a difference of 5% to 10% in the time required for interstellar travel. This temporary inconsistency annoys military tacticians and strategists-it will hinder many coordinated operations.

9.8 23 10: menarche

The earth government announced the first of a series of colonial spacecraft to the public-the applicant was quite enthusiastic. The situation on the earth is getting worse because of overpopulation, so it is naturally an attractive choice to go to alien colonization by spaceship.

Each colonial ship is equipped with military personnel and frigates, which helps to make better use of the existing huge fleet. After the disintegration of heretical armed forces, the army is consuming huge military expenses and materials.

Because superluminal travel is still very novel and expensive at this stage, colonial residents and military personnel must pass strict physical and psychological tests. In principle, only the best citizens and soldiers can be allowed to colonize the "neighboring" world. This is the birth of the near-earth colony.

9. 10 2362: Exploration

The Odyssey was launched on June 65438+1October 65438+1October 2362. As the leader of a powerful colonial fleet, the expedition was full of troops and landscape modification devices, and the colonial spearhead was directed at the New World. The initial stage of human expansion beyond the boundaries of the solar system began.

9. 1 1 2390: Near-Earth Objects

By 2390, the colonial movement in the near-earth colonies was in full swing. A total of 2 10 worlds occupied by human beings are undergoing different degrees of landform transformation, and in the space controlled by human beings, the population burden has been greatly alleviated.

The birth of distant colonies

Expansion is still going on. By 2490, there were more than 800 human worlds (all kinds of worlds, from highly civilized interstellar fortresses to remote small settlements) on the arm of Orion in the Milky Way. As the outward expansion continued, the near-earth colonies became political and economic centers, although they were extremely dependent on the raw materials provided by distant colonies.

During this period, the planet Reach (orbiting Eridani, the fifth star in the constellation Bojiang, just like the throat of the earth) became the main shipyard and training camp of UNSC. Zhiyuan is the main manufacturing place of warships and colonial ships, and also the place where special agents and special forces are trained.

9. 13 2525: Star Alliance War begins.

On April 20, 2525, contact with the distant colony Harvest was interrupted. After trying to re-establish contact failed, CMA sent a reconnaissance ship "golden fleece" to investigate. However, as soon as golden fleece arrived in the rich galaxy, contact with the spacecraft suddenly broke down.

CMA rushed to send a fleet of three battleships to Rongfeng Star. Only Hercules, the flagship of the battleship pilot, returned to the distant planet, scarred and suffered heavy casualties. The commander of the warship reported that an alien warship with powerful weapons appeared, which trampled on Fu Xing and wiped out the colony (and possibly golden fleece).

The battle formation soon encountered an alien warship and was closely followed. After two warships were destroyed, Hercules quickly jumped out of the galaxy, but it took Hercules several weeks to return to Zhiyuan because of serious damage.

The earth army immediately raised the alert level and began to actively prepare for the battle plan to recover Fuxing. In February 65438+ AD, the fleet of the Earth Army led by Lieutenant General Preston Cole set out in a mighty way, and sent such a huge expeditionary force so quickly, which is rare in human history.

9. 14 2525: Battle of Abundant Stars

Cole's fleet vowed to avenge the fall of the colonial star and won the encounter with the alien warship-although the price of victory was that Cole lost two-thirds of his effective strength. It was Cole's tactical epiphany in the last few minutes that turned the situation around.

After the army returned to Earth, Cole, who was promoted to general, learned that many peripheral colonies had fallen, and no one lives. Cole began to line up and prepare to intercept the intruders. The ground war and the ship war were quite fierce, and the war spread to the whole distant colony. In a ground encounter, human forces captured an alien intruder. Before they died of injuries, humans learned that these aliens called themselves "Covenant people."

The distant colonial massacre

In the next few years, Colbert suffered a heavy blow, and his outstanding personal leadership and strategic talent did not help. This is a completely unequal contest, and the winning rate of the Star Alliance in the battleship war is even close to four to one.

By June 65438 +065438+2535 10, in fact, all the distant colonies were slaughtered by the Star Alliance. The Cole Agreement, as a military command, established the following principles: All Earth ships must ensure that their interstellar allies cannot find the Earth. When the earth spacecraft is forced to retreat, it must stay away from the route around the earth and even travel through time without calculation.

If there is a danger of being captured by the Star Alliance, even a "blind jump" is not feasible, the captain must order the spacecraft to self-destruct. In addition, the core data of powerful ship artificial intelligence (AI) must not fall into enemy hands. Therefore, part of the Cole Clause also points out that in a state of emergency, the artificial intelligence on board must be transferred or destroyed.

9. 15 2536-2552: Surrounding Near-Earth Colonies

The iron hoof of the Star Alliance has entered the near-earth colony. Years of wars have gradually become a foregone conclusion: mankind can only win local wars, especially ground operations, at a very high price. In the space war, the defeat of mankind caught people off guard, and the colonies fell one after another.

9. 16 2552: The Fall of Zhiyuan

The interstellar coalition finally reached the main military fortress Zhiyuan, which is closest to the earth, and Zhiyuan was destroyed. The cruiser "Autumn Pillar" carrying the last Sergeant Spartan escaped and survived. The so-called "Sparta" refers to an elite combat unit of the super special forces, equipped with formidable Raytheon hammer armor. They are the ultimate artificial arms.

Now, only one Spartan can fight the enemy. Jacob keyes, the captain of Qiuzhu, ordered a long jump with unknown destination in order to abide by Cole's clause, hoping to keep the tracker of the Star Alliance away from the earth.

After the engine turned off, Qiuzhu found herself in a distant and unknown galaxy. There is also an alliance fleet in the galaxy, and there is a planet-sized ring structure-"halo" near them.

9. 17 2552-2553: Earth Movement

After solving the "halo" problem, a few survivors of Qiuzhu joined some survivors of Zhiyuan and returned to Earth after a series of arduous battles. However, at this time, the Star Alliance fleet also invaded on a large scale. Man must fight for his last hometown. The confrontation between the elite in the interstellar alliance and the forces of the ghost beast led to the division of the interstellar alliance. At the end of 2552, the elite uprising fleet headed by the arbitrator Tyre Vaida and the commander of the Star Alliance Fleet Vatumi fought with the Prophet Ghost Fleet headed by the Truth Prophet and Ghost Beast Leader Ta talos. At this time, the prophet has found the entrance to the "Ark" on the earth, and the elites have formed an alliance with mankind and headed for the mysterious "Ark".

9. 18 2553: Battle of the Ark, the war ended.

The sergeant and others stopped the plot of the prophet of truth to destroy the world on the ark. In order to deal with another threat, they destroyed the ark. However, after returning to earth, everyone looked forward to the sergeant but failed to come back. Everyone mourns the soldiers who died in the war with sadness, but I don't know who carved the number "1 17" in a corner of the monument.
