Is there any literature/documents that detail Rommel's enemies praising him?
There are so many that you can write books on that alone. You can read Desmond Young though. He interviewed many of his old opponents. The only one who wasn't impressed was Eisenhower. But to what extent? I think these can give some ideas, if one uses a broader meaning of "enemies":
-The men who killed him admired him. After his funeral Himmler (who had persuaded Hitler that Rommel needed to be killed) sent a mutual friend, Berndt, to Rommel's family, who were powerless and living in fear, to tell them that it was Keitel and Jodl's responsibilities alone, and he and Hitler did not know! They definitely didn't want to be remembered as Rommel's killers. And Hitler kept his promises that Rommel's family and staff wouldn't be touched, even when he and the Gestapo were certain that Rommel's CoS Speidel was guilty, even when Rommel's young son repeatedly and openly told people he met that his father was murdered. And when the regime was in its dying throes, Hitler still prepared drafts for Rommel's monument.
-When the US named their bombing campaign Operation Desert Fox, there were suggestions that it was disrespectful towards those who fought under him. In fact the veterans thought that it was an insult to Rommel http://www.nytimes.com/1998/12/19/us/impeachment-the-public-the-battle-finds-a-small-community-split.html
-His son Manfred was made Guardian of Jerusalem and he was told that his father protected North African Jews http://www.jta.org/1987/06/17/archive/jerusalem-medal-to-stuttgart-mayor-son-of-general-rommel Even Ariel Sharon openly stated that he copied Rommel's system and I've heard Jewish scholars called him the Jewish Rommel many times. The Arabs called him the Liberator, "Heil Romme" was popular and to this day his name was still used for boys.
