As many who have followed lately Grizzly Adams, Smith and I have been talking through a tread in the Wild Bunch. This was on USMC/USN Persona's during the Invasion and Occupation of Vera Cruz. Others have discussed the Pershing Expidition into Mexico. I wanted to add something about other Expiditions that were going on during this time.
The Banana Wars
Panama, United States interventions in the isthmus go back to the 1846 Mallarino-Bidlack Treaty and intensified after the so-called Watermelon War of 1856. In 1903, Panama seceded from the Republic of Colombia, backed by the US government,[1] amisdt the Thousand Days War. The Panama Canal was under construction by then, and the Panama Canal Zone, under United States sovereignity, was then created (it was handed down to Panama as of 2000).
Nicaragua, which, after intermittent landings and naval bombardments in the previous decades, was occupied by the U.S. almost continuously from 1912 through 1933.
Cuba, occupied by the U.S. from 1899 to 1902 under military governor Leonard Wood, and again from 1906–1909, 1912 and 1917–1922; governed by the terms of the Platt Amendment through 1934.
Haiti, occupied by the U.S. from 1915 through 1934, which led to the creation of a new Haitian constitution in 1917 that instituted changes that included an end to the prior ban on land ownership by non-Haitians. Including the First and Second Caco Wars.[2]
Dominican Republic, action in 1903, 1904, and 1914; occupied by the U.S. from 1916 through 1924.
Honduras, where the United Fruit Company and Standard Fruit Company dominated the country's key banana export sector and associated land holdings and railways, saw insertion of American troops in 1903, 1907, 1911, 1912, 1919, 1924, and 1925. Writer O. Henry coined the term "Banana republic" in 1904 to describe Honduras.
Other Latin American nations were influenced or dominated by American economic policies and/or commercial interests to the point of coercion. Theodore Roosevelt declared the Roosevelt Corollary to the Monroe Doctrine in 1904, asserting the right of the United States to intervene to stabilize the economic affairs of states in the Caribbean and Central America if they were unable to pay their international debts. From 1909 to 1913, President William Howard Taft and his Secretary of State Philander C. Knox asserted a more "peaceful and economic" Dollar Diplomacy foreign policy, although that too was backed by force, as in Nicaragua.
This time period sparked a Marine Corps Publication of the small wars manuel, The Strategy and Tactics in Small Wars Manuel 1921.
