Can someone please help me interpret this portion of the 13th century London Coroners Rolls?

by tlf9888

I'd like to start off by saying that yes, this is for my homework but I am not asking anyone to do it for me. I'm writing an analytical essay for my Early British History class using the London Coroners Rolls but I'm not sure what a specific sentence means; could someone please explain it?

Background: A man committed a murder, was found two days later by the sheriff and chamberlain who he admitted to the crime to (although it doesn't say if he was submitted to any ordeals beforehand.) The sentence I'm having trouble with is the second to last sentence, it says, "And the port of Dover was assigned to him, and to set sail in three days there-from."

I assume this means Dover, England but would he be banished to there, from there, or something else and was this common?

This is the book I'm using, the one I'm looking at now is on page 5 starting with "In the Ward of William de Hadestoke."

The clue is in the sentence above, where it says that 'acknowledging [...] that he had committed the felony before-mentioned, [he] in their presence abjured the realm.' Abjuration of the realm means that you give up all your goods and your nationality, go to some port (in this case, Dover) and take the next ship to anywhere that wasn't England.
