Les miserables timeline

John and Cosette go back and fro to different houses to stay in, knowing they are constantly being pursued by javert and the police. They finally take safe refuge in a gardeners home whom John recognizes from his mayorship.
And so they stay there for some time. (place is near Austerlitz bridge)

Marius- a former royalist and Grandson of Guillenormand, leaves his home.

He had just witnessed his fathers death (Marius did not know his father). His father was a devout Revolutionist, and Marius decided to change his way's to his fathers ways.

Guillenormand could not stand his grandson's change (as he himself was a complete royalist) and so kicked him out of the house.

Marius also learned that his father was saved in battle by a comrade. Marius says to himself that he is indebted to his father's saviour. The comrades name: Thenardier

Marius find's out that thenardier, his father's saviour was actually a dirty bandit eager for money.

Louis Phillipe is made king of france.

Marius and Cosette, who have now grown up to be bright youths of their age, properly see each other (not the first time) at the Rue Plumet gardens.

Marius and Cosette meet each other almost every single day together in the Rue Plumet gardens. Their relationship grows with nobody around them.

Marius (who is now completely in love with Cosette) re-visits his grandfather to marry Cosette.
His permission was denied.

While Marius was at his grandfathers house, John Valjean felt it was not safe to stay there any longer. They prepare to go to London.
Cosette could not disobey her guardians commands.

ABC, the organization Marius had joined in create barricades to oppose the government. Marius and eventually John Valjean joined the group to fight for independence.
Javert who was there as a spy for the police, is caught.
John Valjean saves Javery by letting him go.
The group holds out until the next day, in which the royal battalion bring in cannons to destroy the barricade and managed to kill most of the people in ABC. John Valjean carry's out the unconcious Marius and saves him from death.

Javert, ashamed that he has been saved by a criminal, suicides soon thereafter.

Cosette and Marius finally marry together.

Thenardier arrives at the household attempting to degrade John Valjean by showing his crimes, whilst actually showed proof that he performed miraculous deeds that were kept hidden from most people.

Marius pays his debt to Thenardier unwillingly by throwing sacks of money at him.

John Valjean knows he cannot keep Cosette any longer and is in pain. He soon dies in mid October, leaving behing and enourmous amount of money to his new family.
