Operation Husky has been well covered over the years. From the Allied side, there are superb official histories by the British, US, and Canadian armies, as well as accounts by the Royal Navy, US Navy, and US Army Air Force. Many of these histories were written in the 1950s and so the vital issue of Allied Ultra signals intelligence was not openly discussed. Fortunately, the superb Hinsley study has a chapter devoted to this subject. Besides the published studies, there are numerous specialized reports and monographs, many unpublished, covering the campaign. From the Axis side, the Italian perspective is covered by an account by Guzzoni’s deputy, Gen. Faldella, as well as Santoni’s more recent official history. The US National Archives and Records Administration in College Park, MD (NARA II) has an extensive collection of captured Italian army documents, including excellent order-of-battle data on Italian dispositions on Sicily. There is no official German account, though there are a variety of accounts contained within the US Army’s Foreign Military Studies series by German commanders. Several of these were collected under the omnibus T-2 study. The most detailed English-language account of the Axis forces on Sicily was prepared under the direction of Magna Bauer to support the US Army’s official “Green Book” history of Husky. The Bauer study consists of 18 separate reports in the R-114 to R-147 series, totaling over a thousand pages. It has not been published but it is available at NARA II. Dozens, if not hundreds, of divisional and other unit histories from formations participating in Operation Husky have appeared in print, but they are not listed here owing to their sheer volume.
