The Confederacy depended on exporting raw materials, especially cotton produced through enslaved labor, to pay for the manufactured goods needed at home and by its armies. The plantation system rested on coerced, unpaid labor, a fact the discussion refuses to hide behind euphemism. A simplified sixty-percent interception example shows why a blockade need not be airtight. Every lost export reduces the money available for imports, and every lost import further reduces the capacity to produce the next round of exports. The resulting cycle produces diminishing returns even when some ships continue to get through. Celebrated blockade runners provide dramatic stories, but successful voyages cannot reverse the cumulative loss of exports, purchasing power, and replacement machinery. Blockade works here through compounding economic damage rather than the absolute elimination of traffic.

The Anaconda Plan and compounding trade pressure
The Anaconda Plan illustrates why a blockade can be strategically decisive even when many blockade runners still get through: each lost export also reduces the enemy's ability to finance later imports.
