Is the Great Inland Sea in "the long patrol" (book)

[Faiyloe]

In "the long patrol" the Rapscallions first attacked Salamandastron and then they fled to a sea somewhere south west of Redwall. Could this be the same as the Great inland sea in "Salamandastron" and "Marlfox"?

• It seems illogical that The Rapscallions could have sailed all the way around the cost to the other side of the continent.
• It was also reported that they seemed to have just slipped out of existence and they couldn't be found anywhere. What better way to diaper then to sail down a river inland when you are being looked for on the coast.

It said they were on the Southeastern coast I think.

[Faiyloe]

that's not what the map shows in the book.
