Are the phrases "not yet a week passed" grammatically correct?

Question

--------------------------
Not long after that, the marine controlled the beach and the infantery troops entered. *Not yet a week passed*, all inch of the land in the island have been controlled by the military.

(another question: "all inch of the land" is a correct english phrase?)

Answer 1

"Not yet a week" = not even a week has/d passed
"all inch of the land" = Every inch of the land

I think that they are correct. The grammer is more poetic in intention

Answer 2

"A week had not yet passed".

"Every inch of the land"
