Question: How and why did Duke William form his forces?
About the article "Battle of Hastings", section "Dispositions of forces and tactics".

Candidate passages:
After revealing his true intentions to Audrey and leaving her unconscious in a field, William and his henchmen have been tearing Haven apart by amplifying more and more Troubles.
The most recent victim is Doreen, whose newly supercharged Trouble has caused a volcano to erupt, causing havoc in Haven.
Among the injured is Cliff's wife, Suzie.
After dealing with it the best they can, Audrey and Nathan go back to Audrey's apartment over the Grey Gull and fall asleep together.
The next morning, Audrey finds herself alone on the floor in pajamas and no shoes.
The Grey Gull has been changed to Jojo's Bait Shop and, walking to Haven barefoot, she is picked up by Detective Duke Crocker, a third-generation Haven PD cop whose father is Chief.
There is a vandalized realty sign showing Suzie and another man.
They make a stop as Duke has to take a witness statement for the vandalism, and Audrey meets Vince and Dave, who don't recognize her and think she is a homeless person.
They walk off revealing the Haven sign which reads "The safest town in Maine" and she realizes that she is in a Haven where the Troubles do not exist.
Detective Crocker wants her to do a psych evaluation and at the hospital she meets Nathan, who is now Dr. Nathan Hansen (his father being Max Hansen).
She encounters William, and they both see Nathan with his daughter and wife.
William is determined to bring the normal Haven back, with or without Audrey's help.
He yakes one of her hairs and leaves.
He goes to see Vince and Dave Teagues, as Audrey meets up with Duke, explaining to him that William is dangerous.
A murder call comes in: Vince and Dave are both dead.
A blonde hair is found on Dave and Audrey is arrested for their murder.
William acts as Audrey's lawyer and asks her to help find the Troubled person responsible for the new Haven.
Nathan's family is missing and William calls him, asking to speak to Audrey, who is released from custody.
William has kidnapped the Hansens and forces Audrey to find who has changed Haven.
Nathan can't understand how it could happen in Haven, as there is never any crime.
Audrey recalls the vandalized sign and decides to find Suzie in the hope of understanding what has happened to Haven.
Suzie doesn't recognize Cliff who has been following her around.
Audrey with Nathan talks to Cliff who quickly explains that when Suzie died from her injuries he wished for the Troubles to be gone.
The cost of the wish, however, is that she doesn't know him.
Duke tracks Nathan's cellphone to where he is with Audrey, but Nathan and Cliff go to meet William in exchange for Nathan's family.
Duke believes Audrey's story.
They find Cliff tied up, and they are threatened by William, who shoots Duke.
He asks Audrey why she is the one who has to deal with the Troubles.
He tells her she is the one who created the Troubles along with him and she is being punished for it.
He knows because they did it together.
Nathan arrives and picks up Duke's gun, telling William to drop his.
William instead shoots Cliff and Audrey suddenly wakes up in bed with Nathan.
That morning Nathan learns that Suzie has died from complications and Cliff is found shot dead.
Audrey, Nathan and Duke find William at an abandoned warehouse.
William learns that Audrey hasn't told her companions what he told her and explains that Audrey and he are connected.
Before he can say more, however, Nathan shoots him and, as he falls, so does Audrey, having the same gunshot wound as William. 
Explanations advanced for why the revolution happened and took the form it did include actions of the Shah and the mistakes and successes of the different political forces: 
In the "near future" year 1998 (Duke mentions that he had defeated Dr. Proton the previous year), the evil Rigelatins plan to enslave Earth, and they kidnap Duke Nukem (who was performing in an interview about his new autobiography "Why I'm So Great"), to use his brain to plot the attack for their forces.
Duke breaks free to save the world, again. 
Detailed history of divisions in the Ernestine line.
Elector Ernest died in 1486, and was succeeded by his son, Frederick III, the Wise.
Leipzig, the economic center of Saxony, as well as the seat of the only university in Saxony, was located in Albertine Saxony.
Wanting a university in his lands, for example for educating civil servants and pastors, Frederick founded the University of Wittenberg in 1502.
It was there that Martin Luther posted his 95 Theses.
Frederick protected Luther, refusing to extradite him to Rome for trial.
Frederick, as did other German princes, allowed Lutheran reforms to be implemented in his domain.
Frederick III died in 1525; he was succeeded by his brother, John the Steadfast (1525-1532).
John was a leader in the Schmalkaldic League of Protestant princes in the Holy Roman Empire.
John died in 1532 and was succeeded by his son John Frederick I.
For the first ten years of his reign, John Frederick shared the rule of Ernestine Saxony with his stepbrother, John Ernest, titularly Duke of Saxe-Coburg, who died childless.
John Frederick increasingly hardened his support of the Lutheran Reformation, while the Emperor, Charles V, avoided direct confrontation with the Protestant princes, as he needed their support in his struggle with France.
Charles eventually came to terms with France, and turned his attention to the Protestant lands of the Holy Roman Empire.
In 1546 the Schmalkaldic League raised an army.
Elector John Frederick led the league's troops south, but shortly thereafter John Frederick's cousin, Duke Maurice of Albertine Saxony (Meissen), invaded Ernestine Saxony.
John Frederick hurried back to Saxony, expelled Maurice from the Ernestine lands, conquered Albertine Saxony and proceeded to invade Bohemia (held directly by Emperor Charles V' brother Ferdinand and that latter's wife Anna of Bohemia and Hungary).
Charles' forces drove the Schmalkaldic League troops back and decisively defeated them in the Battle of Mühlberg (1547).
John Frederick was wounded and taken prisoner.
The Emperor condemned him to death as a rebel, but stayed the execution because he did not want to take the time to capture Wittenberg, defended by John Frederick's wife Sybille of Cleves.
To save his life, John Frederick conceded in the Capitulation of Wittenberg to resign the Electorate and the government of his country in favor of Maurice of the Albertine Saxony, and his punishment was changed into imprisonment for life.
When the newly minted Elector Maurice, having again changed sides, attacked the Emperor, Duke John Frederick was released from prison, and given back the Landgraviate of Thuringia.
He established his capital in Weimar, and started a university at Jena (to replace the one in Wittenberg lost to Maurice) before his death in 1554.
The three sons of John Frederick I shared the territory, with John Frederick II becoming head (and briefly, 1554–56, holding the electoral title) with his seats in Eisenach and Coburg, the middle brother John William staying in Weimar (Saxe-Weimar), and the youngest, John Frederick III (namesake of the eldest brother, which thing has caused innumerable confusion in history writing) establishing residence in Gotha (Saxe-Gotha).
When John Frederick III of Gotha died unmarried and heirless in 1565, John William of Weimar tried to claim succession to Saxe-Gotha, but the sons of the imprisoned John Frederick II entered their own claim.
The contenders reached agreement in 1572 in the Division of Erfurt by which John William added the districts of Altenburg, Gotha and Meiningen to Saxe-Weimar.
When John William died a year later, his older son, Frederick William I received Altenburg, Gotha and Meiningen with using the title of Duke of Saxe-Altenburg, and with his several sons founding the first Saxe-Altenburg line, while Saxe-Weimar went to the younger son John II.
John Casimir (d 1633 heirless), the older son of John Frederick II, and John Ernest (d 1638 heirless), the younger son of John Frederick II, received together the territory of Saxe-Coburg-Eisenach, but got a legal guardian because they were underage.
In 1596 the brothers agreed to split the duchy into Saxe-Coburg and Saxe-Eisenach.
Johann II, Duke of Saxe-Weimar (or John II), died young leaving eight surviving sons (including Bernhard of Saxe-Weimar, the youngest, the famed general) and a will ordering them to rule jointly.
When the eldest of them, John Ernest III, Duke of Saxe-Weimar died in action (1626) unmarried, two more of his brothers were already deceased without children, leaving five dukes of Saxe-Weimar, with Wilhelm the eldest.
Two more died within fifteen years, including Bernhard in 1639, without heirs.
In 1638, the senior Coburg-Eisenach line went extinct and its possessions were divided between the Altenburgs and the Weimars, this doubled the Saxe-Weimar possessions and made it again feasible to be divided.
In c 1640, the remaining brothers finally divided their patrimony, William remaining in Weimar, Albert (Albrecht) receiving seat as Duke of Eisenach and Ernest (by-named "the Pious") also got his share and became known as Duke of Gotha.
Ernest I, Duke of Saxe-Gotha (1601–75) had married Elisabeth Sophie, the only child of John Philip, Duke of Altenburg and Gotha (1597-1638), the eldest son of Frederick William I.
When Elisabeth Sophie's cousin Frederick William III, Duke of Altenburg, died unmarried 1672, the entire first Altenburg line went extinct in male line, opening a succession strife.
Ultimately, Ernest and Elisabeth Sophie's sons received the lion's share of Altenburg inheritance, on basis of Duke John Philip's testament (as it was ultimately recognized in law that the Salic Law does not prevent an agnate to will all his possessions to those other agnates of the house he desires to make his heirs, leaving other agnates without; and if those favored agnates also happened to be the testator's son-in-law and maternal grandsons, that's in no way prohibited), but a portion (one fourths of the original Altenburg moiety) passed to the Saxe-Weimar branch.
These two lines: Weimar and Gotha(-Altenburg) form the basis of future Ernestine lines, and both have surviving male lineage up to today.
After the division of the inheritance of the first Altenburg line, the senior, Weimar, line held somewhat less than half of the Ernestine lands, and the junior, Gotha-Altenburg, line held more than half.
Gotha-Altenburg line subdivided more and Weimar line not so much, and ultimately all the said Weimar line's possessions were concentrated in primogenitural hands in 1741 and in 1815 were raised to grand ducal title of Weimar.
Duke Ernest of Gotha and Duchess Elisabeth Sophie's numerous sons divided the inheritance (five eights of all Ernestine lands) initially to seven parts: Gotha-Altenburg, Coburg, Meiningen, Römhild, Eisenberg, Hildburghausen and Saalfeld.
Of them, Coburg, Römhild and Eisenberg did not survive over that one generation and were divided between the four persevering lines.
The Ernestine territories in Thuringia were thus divided up and recombined many times as Dukes left more than one son to inherit, and as various lines of the Ducal Ernestines died out in male line.
Eventually, primogeniture became the rule for inheritance in the Ernestine Duchies, but not before the number of Ernestine duchies had risen to ten at one point.
By 1826 the remaining Ernestine duchies were the Grand Duchy of Saxe-Weimar-Eisenach (approximately three eights of all the Ernestine lands), and the ("Elisabeth-Sophie-line") duchies of Saxe-Gotha-Altenburg, Saxe-Meiningen, Saxe-Hildburghausen and Saxe-Coburg-Saalfeld.
In 1826 Ernest the Pious' senior line, the Gotha-Altenburg, went extinct.
The daughter of its penultimate duke had been married with Duke of Coburg and Saalfeld, and the couple had two sons (younger of whom was to become Albert, Prince Consort of the United Kingdom).
The patrimony of Gotha-Altenburg was divided between the other three lines stemming from Ernest the Pious and Elisabeth Sophie, causing changes in nomenclature: onwards, they were Saxe-Meiningen-Hildburghausen, Saxe-Altenburg (the former Hildburghausen line) and Saxe-Coburg and Gotha - the youngest line (originally Saalfeld line) receiving the "maternal" seat of Gotha which had been the seat of Ernest the Pious, progenitor of all these seven lines.
All of the Ernestine Duchies ended with the abolition of the monarchy and princely states in Germany shortly after the end of World War I.
Five of the Ernestine duchies were members of the Upper Saxon Circle of the Holy Roman Empire: Saxe-Weimar Saxe-Eisenach Saxe-Coburg Saxe-Gotha Saxe-Altenburg Membership in the Circle gave the ruler of a state a vote in the Reichstag.
In the 1792 Session of the Reichstag, the Duke of Saxe-Weimar was also the Duke of Saxe-Eisenach, and had two votes (as well as three-eights of all the Ernestine lands); the Duke of Saxe-Altenburg was also the Duke of Saxe-Gotha (as senior heir of both Duke John Philip and Duke Ernest the Pious), and had two votes; and the Duke of Saxe-Coburg had one vote.
The other Ernestine duchies were never members of the Imperial Circle, and did not have the right to vote in the reichstag as the five duchies that the other duchies did (for example, the principalities of Meiningen and Hildburghausen were such; that was one reason why Duke of Saxe-Hildburghausen exchanged his patrimony to that of Altenburg).
However, they were all autonomous and ultimately, with the dissolution of the Holy Roman Empire, the issue became irrelevant.

From a modest background, he was educated locally and did not attend a public school or university.
