War & Military 1920's

What led the U.S. to join the War

  1. Close ties to England made the U.S. an enemy to Germany immediately
  2. The Sinking of the Lusitania When the Germans sunk the Lusitania in 1915, a passenger ocean liner with 159 Americans on board, the public opinion in the United States toward the war began to change. This act killed 1,198 innocent passengers. When the United States finally entered the war two years later, the cry "Remember the Lusitania" was used on recruitment posters and to unite the people against the Germans
  3. Zimmerman Telegram In January of 1917, the British intercepted and decoded a secret telegram sent from German Foreign Secretary Arthur Zimmerman to the German ambassador in Mexico. He proposed that Mexico ally with Germany against the United States. He promised them the territories of Texas, New Mexico, and Arizona.

WWI 1914-1918

The U.S. was only in the war for 1 year and 7 months

There number of civilian and military casualties numbered 38 million (worldwide)

American Military casualties were 53,402

Before WWI the Active Army and the national guard numbered 200,000 and after the draft it was 4,355,000

Soon after troops were no longer needed they were disbanded

At home during 1919-1921 the active army played the role of the National guard (that was not yet reorganized)

At home during 1919 and 1920 the Army forces continued to guard the border of Mexico required by revolutionary disturbances in that country. Because of the lack of National Guard forces, the active Army until the summer of 1921 also had to supply troops on numerous occasions to help suppress domestic disorders, chiefly arising out of labor disputes and race conflicts in a restless postwar America.

Treaty Of Versailles 1919

Because the U.S. rejected the Treaty of Versailles the United States was technically at war with Germany until a separate peace was signed during the summer of 1921.

The last occupying U.S. forces in Germany left for home on January 24, 1923

  1. Woodrow wilson came up with the league of nations but the American government and the people did not want to join it.
  2. The American people wanted to go back to a stage of isolationism.

Disarmament

In the early 1920's major combatants of the war met to try and agree on a reduction in weapons.

Though the public was in favor of disarmament, politicians and military leaders maneuvered their armed forces to their best advantage, since unresolved tensions were still left from WWI.

Advancement in weaponry

In 1922 the Navy developed a radio-controlled battleship that could be used in joint exercises with Army and Navy air forces to test aerial bombing attacks on warships traveling at speed while taking evasive measures.

To provide air cover and attack capability at sea required a new type of ship - the aircraft carrier.
