As I remember it, the only controversy was which level was the "real Troy" of the Trojan War; not whether the site itself was the site of Troy.
We need SC to dredge up some of the archival matterial.
Carl Blegen (the American excavator) thought it was Troy VIIa; Dorpfeld (the second German, Schliemann’s protege’) thought it was Troy VI. I agree with Dorpfeld. :’) The “Jewels of Helen” were stolen by the Red Army at the close of WWII (honestly, who can blame them?) but were probably grave goods dug down into the lower levels from Troy III or IV. :’)
