Elms, Matthew. When the Akimotos Went to War: An Untold Story of Family, Patriotism, and Sacrifice during World War II. Arlington, VA: American Battle Monuments Commission, 2015. Print.
This book was written about the Akimotos, a Japanese American family. Connecting Japanese American Internment to the famous 442nd/100th Battalion, this book was very useful to understanding the historical context of anti-Asian sentiment in America. This book was biased in favour of Japanese Americans in that it was told to represent their perspective. We used this book to develop the middle section of our project about Japanese Americans becoming soldiers in the US Army. Published by the US government agency, American Battle Monuments Commission, this is a reliable source due to the variety of primary sources and the evidence is corroborated by other sources. We found this book in our school library.
