By the most bizarre of coincidences, the day on which the putsch was decided — 12 April 1961 — was also the centenary of the day on which South Carolina batteries opened fire on Fort Sumter, thereby sparking off the American Civil War.

XREF: Connects the April 1961 putsch (likely Algerian generals' coup) with the American Civil War centenary, both occurring on 12 April.
