Manning the Rammas Echor

This is one of those math story problems I hated in school; hence, I became an English major.

But as an English major once force-fed a wide range of world literature (some of which I even enjoyed), I believe the answer is obvious...

42.

P.S. Considering a "league" is 3 statute miles (thus Rammas Echor was approximately 30 miles long), the correct answer would be that Gondor, even at the height of its power, could not man the whole wall; therefore small forts or bastions judiciously-spaced were the more likely means of defense.
