The chronological events in Shakespeare's "Hamlet" are the following:
1. Hamlet and Horatio come upon the grave diggers.
The gravediggers do not recognize Prince Hamlet, who picks up a skull and is told it belonged to King Hamlet's jester, someone he remembers from his childhood.
2. A funeral procession, including the King, Queen, and Laertes arrives at the grave site.
The funeral procession for Ophelia, who has committed suicide, arrives at the churchyard with Claudius, Gertrude and Laertes.
3. Upset by Laertes' showy display of grief, Hamlet also jumps into the grave.
Laertes jumps into the grave to hold his late sister and Hamlet declares his love for Ophelia.
4. Hamlet and Laertes fight, but Claudius orders attendants to separate them.
They must be separated after Hamlet proclaims he loves Ophelia more than Laertes and that he would eat a crocodile or be buried alive for her.
5. Claudius reminds Laertes that his time for revenge will soon come.
King Claudius has already a plan to make Laertes kill Hamlet in a sword fight or to murder him by offering some wine.
