In Hawaii the army asked for 1500 volunteers. How many showed up?

10,000 volunteers showed up.

Explanation:

After the Pearl Harbor attack on Americans by the Japanese on Dec. 7, 1941, The Japanese-Americans living in the U.S. were viewed as enemies of the state which saw to the ordering of Japanese Americans out of Thier homes  to the internment camps  by the Federal government.

In 1943, President Roosevelt authorized that  Japanese-American men be enlisted into the U.S. Armed Forces to act upon the request  by the Japanese American organisation propaganda that Japanese American be out of the camps.

In order to prove that they were not enemies of the state, the Japanese American males were allowed by choice  to join the millitary but would  form a seperate infantry outfit  – it was noticed that in Hawaii which had not experience any confinement to interment camps , 10000 volunteers showed up upon the army's request of 1500 volunteers.

The seperate infantry unit formed was later referred to the  442nd Infantry Regimental Combat Team which fought alongside the 100th infantry battalion and saw many victories starting from June 1944,  in Italy Rome and then Germany etc.
