There were many during the war. The most famous, from an American perspective, is probably the Bataan Death March, which happened in 1942 in the Philippines. Japanese soldiers forced captured American and Filipino soldiers to march 80 miles from Bataan to a prisoner camp, and hundreds (maybe even thousands) of these prisoners died due to ill treatment during the march.
There were also others. For example, as the Soviets started "liberating" German occupied zones in eastern Europe, the Germans would force concentration camp prisoners to go on death marches to camps closer to Germany. The Japanese also had somewhat similar marches (besides the Bataan one). Even those who fought against the Axis Powers were not above having them- notably, in Brno, Czechoslovakia (now the Czech Republic), thousands of Germans were forced to leave because the Czechs were upset at what the Nazis had done to them during the war.
It was in Bataan in the Philippines.

The Filipinos who were not in the march and the Japanese Soldiers were the people who did filming and took photos of the march and the atrocities of the Japanese. The Filipinos have a museum of the Bataan Death March and a monument. See related link below. That site also gives you other links.

The Bataan Death March was not a battle. It was a forced death march, e.g. being forced to march at least 80 miles under extreme conditions. Over 10,000 soldiers died during The Bataan Death March.
If you need to find someone that was part of the Bataan Death March the Filipino people have made a computer database of who was on that death march. You can contact that tourism board about the Bataan Death March victims. They have a national site there and an office of people who have the database records. I have added a web page to get you started on contacting them. There are databases of survivors here in the US but the entire database of the 75,000 people is in the Philippines. Do not worry about language problems. They speak and write English better than some of us Americans.
