I have recently come across a beautifully produced website on Latvian Displaced Persons and life in the camps. Dieva Putnini which translates to Little birds of God's has an English, Latvian and German translation. Most of the site is in Latvia. It looks at life in the camps, and migration around the world. It features some fantastic photographs as well. As the Lithuanian story is so similar to the Latvian one, this may be of interest if you are wanting to know more.
