April 27, 1805 — The Battle of Derna commences

The first extra-territorial land battle fought by the armed forces of young United States of America. It is the source of the Marine Corps Hymn (“To the Shores of Tripoli”), because the American forces – which consisted mostly of a few hundred mercenaries, backed by three ships – were led by 54 marines. It was the decisive engagement of the First Barbary War (fought between the United States and Sweden on one side and the so-called Barbary States – the Eyalet of Tripolitania and Morocco – on the other).

The battle itself took place after the mercenary forces, led by 8 US marines, attacked the fort at the city of Derna, taking it after heavy fighting against a greatly numerically superior enemy. The surrender of the Barbary forces came a month later, and the US set an early precedent for its poor treatment of its veterans by stiffing the mercenaries on part of their pay.

April 28, 1965 — US Marines occupy Santo Domingo

The Dominican Civil War was not even a week old before Lyndon Johnson decided that it posed a threat to US interests (to be fair to Johnson, the Cuban Missile Crisis was only three years earlier, and Johnson was worried that ‘another Cuba’ was about to form). The US Marines landed near Santo Domingo (the capital of the Dominican Republic) on April 28, and had captured the city within a day or so – the Constitutionalist forces surrendered the city on the following day.

The Dominican Civil War dragged on until September, and American forces remained in occupation until July of the following year, when somebody the US liked could be elected.
