The Nazis had several methods of slaughtering the Jews that were in concentration camps. Their main goal for this was to kill the inferior race as they called them. Little do they know that in God's eyes they are far superior than any other nation and any nation that goes against them no matter what way, will suffer the wrath of God before he's done with them.
In any case, they were killed any number of ways. If starvation or overwork didn't kill them, then they burned them or gassed or tortured them in various ways and the torture was so horrible that most of them died from it.
Watch the Holocaust or The Hiding Place or The Boy in the Striped Pajamas. They are all movies that show some of what happened to God's chosen people.
Despite the help given by Italy and Germany to the Falangists and Franco during the Spanish Civil War (1936-39), Franco refused to give military support to Germany or Italy in WW2 (except that a few thousand Spanish volunteers fought on the Eastern Front).

However, since the United States' strongest ally was the United Kingdom, both FDR and Churchill found it more prudent to put the strongest effort in winning the war in Europe before turning their effort more strongly to the Pacific.
Naturally, because of the declaration of war, the United States ceased trade with the Axis powers and all Axis-Occupied Countries or Partners.
Although I can't answer the question directly I can tell you of a unit that served there. 537 Coast Regiment Royal Artillery was stationed there with 205 Battery at Skanse and 421 Battery at Naes.
I am not 100% sure but I think that Germany was blamed for starting the WW1. (they did not) and France was left in disaster after WWI. Their land was dug up from trenches and almost half of their male population was killed (could have been WW2 don't remember) But anyways, they decided to force Germany to pay them for all the damage the caused... The only problem was that Germany didn't have any money and was in major financial problems itself. So this made the Germans desperate for someone to stabilize and regrow the economy (that's how Hitler came to power)
