Russia intervened to prevent British and French (two of the countries with Rothschild banks) intervention on behalf of the Confederacy. It was both a show of good faith to the Union and payback for British/French behavior in the Crimean War a decade before.

Jews never forgive. They hold grudges for all eternity. And Russia’s pledge of support to the Union kept them from reestablishing the slave trade under the Confederacy. Also oy vey don’t look into Judah P. Benjamin!
