25 APRIL 1862 · THE AMERICAN CIVIL WAR, 1861–1865

24–25 Apr 1862 — Farragut runs his fleet past the river forts in the dark and takes the Confederacy’s largest city and richest port without a siege. The mouth of the Mississippi is corked from the sea.

THE MOMENT IN CONTEXT

A blockade works through arithmetic rather than drama, which is why its effects were easy to underestimate at the time. It did not need to stop every ship, only to raise freight, insurance, delay, and loss until fewer useful supplies arrived at a far higher price. The growth of the Union navy from a few dozen ships to hundreds made that pressure stronger each year. Occupying the coast produced a second consequence its planners had not fully intended, because at places such as Port Royal enslaved people escaped to the fleet and forced commanders to decide whether federal forces would return human beings to their claimants or treat them as free.

From Chapter 4 — The Anaconda and the Rivers of The American Civil War, 1861–1865 (APR 1862).
