Note 21 — XVIII THE GENESIS OF TWO CAMPAIGNS July, 1846—February, 1847
Reading edition
“Norther” was the name given to an extremely violent wind which blew at frequent intervals from October to April, lasting usually about three days. During Scott’s operations one lasted seventy-six hours. It grew more violent as one went south toward Vera Cruz, probably because the cordillera approached the coast and produced somewhat the effect of a funnel. Its merit was that it prevented yellow fever.
