if referring to concentration camps Washington had received information about such camps but there was nothing that could be done due to war time. the matter was stressed to President Roosevelt by Jewish groups during th war.........

Ordinary concentration camps (like Dachau and Buchenwald, for example) were public knowledge before the start of World War 2. The Allies knew about the extermination camps since the first of them started (December 1941) but did not want to know. They saw them as a distraction from World War 2.
While the Nazis did try to keep secret the what they were doing in the camps; their existence and use was well know to the allies before they were captured at the end of the war. Even though they were briefed on what they would find, the troops were all shocked and horrified. May had lifelong mental trauma as a result of the horrors they found in the camps.
The Allies were well informed thanks to the efforts of the various resistance movements, though information about exact locations did not reach them immediately. However, it seems that they did not really want to know about the Holocaust.
Because they did not know what was going on in the camps, they thought it was more of a prison camp than a death camp
The Allies had some knowledge about the Nazi concentration camps before they liberated them. Reports and intelligence gathered by various agencies, underground resistance groups, and individuals provided information on the existence of the camps and the atrocities being committed. However, the full extent of the horrors and the systematic genocide was not fully grasped until the camps were liberated and the evidence was uncovered.
The Holocaust had been kept secret by the Nazis as far as possible. They knew that it did not have the active support of the majority of Germans. They knew that they had committed appalling atrocities and wanted to hide them from the rest of the world. _____________ Well, because they knew if the Russians knew about the holocaust they had created, they'd all be in big trouble. The holocaust was hidden, no one really knew, and during that time period (and some now) people doubted the fact it happened. After the war, people like Auschwitz commandant Rudolf Hoess were hanged for war crimes. ______________ Actually the US government and other governments around the world new about the Concentration Camps/Labor Camps, it just wasn't public knowledge. The Allies did not know about the Death Camps though, so the Germans spend the last years of the war trying to eliminate the Jews (They blamed the Jews for defeat in WW1) via mass slaughter at the Death Camps. Germans did not want the allies to find out out about the death camps, so they tried to destroy them. The Russians found the first Death Camps, as the majority were in Poland, since Poland had a high Jewish Population. Around 3 million Polish Jews were killed at the Death Camps. Anyway, the Nazis destroyed the death camps (or tried to), since they didn't want the rest of the world finding out about them.
You should know this, but if you really don't know it's the Allies. (and don't ask me what "Allies" is)
The Allies fooled the Germans by having many fake airfields and army bases set up, complete with thousands of wood and cardboard trucks,tanks and aircraft. -They even had people imitating the famous leaders of the day circulating in the areas of these camps.
i also am looking to join the army but i don't know the
The Holocaust ended in 1944 and 1945, when the Allies began began to liberate the concentration camps. Another big event that ended The Holocaust was the suicide death of Adolf Hitler. After his death many Nazis retreated and went into hiding for fear of the Allies. ___ The Holocaust ended because the American, British, Soviet, and other Allied armies drove into Germany, liberated the concentration camps, and forced Germany to surrender unconditionally. The Allies won the war. Humanity was saved.
Your question is unclear. As a many Jews were in the camps it is safe to assume that they knew of them.
Most Germans did know, at least that the camps existed. Some kidded themselves that they were just forced labor camps. Some knew they were death camps, but as it was "just Jews", they didn't care.
* The death camps were all located in Poland (plus one in Belarus). * With the exception of Majdanek, which was in a suburb of Lublin, they were all in remote places. * The whole operation was classified as Top Secret (Geheime Reichssache). * Some of the death camps were destroyed in 1943 (Treblinka, Sobibor, Belzec). * The other death camps were destroyed as the Soviet Army approached. * On various levels and in various ways, most people didn't want to know.
