An Appellate Court is not (usually) the Court of original jurisdiction. So, in many cases you would start at a Federal Trial Court (District Court) and would have a normal trial. If you lost, you could appeal to the Appellate Court, who would review the record (only) from the Trial Court for clear error, bias, etc. A new trial does not occur at the Appellate Level, unless it is a court of original jurisdiction.
The reason why there is such a difference between civilian deaths in WWI and WWII was that civilians were deliberately targeted in WWII.
<h3>Why were there more civilian deaths in WWII?</h3>
In WWII, the combatants targeted civilians directly in some cases as opposed to WWI where civilian deaths were limited.
For instance, WWII saw the Nazis targeting specific populations such as Jews. The allies also targeted civilian areas during their bombing raids in order to pressure the Nazis to surrender.
