Altavilla Sicily

Activated in May 1942, the 504th Parachute Infantry Regiment earned high praise for its very first mission when it effected the first U.S. mass regimental combat jump of World War II in the invasion of Sicily. According to German General Kurt Student, “if it had not been for the Allied airborne forces blocking the tanks of the Hermann Göring Division from reaching the beachhead, that Division would have driven the initial seaborne forces back into the sea.” Led by Col. Reuben Tucker, the 504th subsequently dropped into the endangered Fifth U.S. Army beachhead at Salerno; bitter fighting led to hard-won success at Altavilla and Hill 424 and the regimental motto “Strike and Hold.” Birth of a Regiment is the first book-length account of the birth of U.S. airborne forces, and the first to fully capture the details, danger, and crucial stakes of the initial 504th missions in the unforgettable voices of the newly minted paratroopers who fought the first Allied battles in the ETO up through the victorious entry into Naples. These initial missions were all the more important, in that they would determine future Allied strategy, planning, and tactics. It is not to be forgotten that Sicily was a testing ground for the Allied coalition: the first time an American army and a British army, managed at the top by a unified Allied staff, would undertake a major campaign. According to James M. Gavin, the Commanding General of the 82nd ABD at the end of the war, who had jumped into Sicily himself: “What was learned in that first cooperative action affected the whole outcome of World War II.” Personally interviewed by the author over a period of 20 years, nearly 200 veterans of the 504th recount their remembrance of combat, permitting readers of Birth of a Regiment to relive epic battles of the ETO through the words of the very men who made history. Participants include survivors and witnesses of the tragic decimation of 23 aircraft and the death of 164 paratroopers and crew when U.S. troops mistook them for the enemy and fired on their planes as they flew into Sicily. Veterans recount the ferocious, desperate battle at Biazzi Ridge, and the later regimental action at the Salerno Beachhead, where the 504th crucially took Hill 424 after a night drop and seaborne landing. Having undisputedly proven their prowess, Tucker’s troopers were chosen to spearhead the Fifth Army drive into Naples. These dramatic, unforgettable memories of the war provide new information from the foxhole view on up, giving historians and lay readers alike fresh perspective on the initial U.S. engagements in WWII and the difficult birth of Allied airborne operations. The volume is enriched by new maps and historic archival photos, including many previously unpublished photos and provided by 504th veterans.

In the four decades since its discovery nuclear magnetic resonance (NMR) has become an indispensable tool for obtaining chemical information often. inaccessible by other methods. With the development of instruments of increasingly higher magnetic field strengths, the integration of powerful computers and the availability of an expanding array of flexible software new applications and developments have proliferated rapidly. Among the more exciting new advances is the use of NMR spectroscopy to probe biological systems. The last ten years have witnessed tremendous progress in the development of new NMR imaging and spectroscopic techniques for research and diagnostic applications. The ability to investigate metabolic processes and anatomical structure of intact biological systems under conditions that are totally non-destructive and non-invasive clearly provides much of the impetus for the intense activity that has been generated in the fields of medicine, radiology and the allied basic sciences. Significant advances have been made in this brief period: Whole-body proton NMR imaging today provides anatomical definition of normal and abnormal tissue with a contrast and detection sensitivity often superior to those of X-ray computed tomography and other competing imaging methods. Biochemical pathways, using NMR spectroscopy of protons, carbon-13 and phosphorus-31 nuclei in live animals and man can readily be followed by surface-coil methods to detect metabolites in localized regions. Indicative of the importance and widespread acceptance of these techniques is the explosive growth that the NMR literature is experiencing. This augers well for the future.

This book represents a collection of lectures presented at the NATO Advanced study Institute(ASI) on "Chemistry & Physics of the Molecular Processes in Energetic Materials", held at Hotel Torre Normanna, Altavilla Milicia, Sicily, Italy, September 3 to 15, 1989. The institute was attended by seventy participants including twenty lecturers, drawn from thirteen countries. The purpose of the institute was to review the major ad vances made in recent years in the theoretical and experi mental aspects of explosives and propellants. In accordance with the format of the NATO ASI, it was arranged to have a relatively small number of speakers to present in depth, re view type lectures emphasizing the basic research aspects of the subject, over a two week period. Most of the speakers gave two lectures, each in excess of one hour with addition al time for discussions. The scope of the meeting was limit ed to molecular and spectroscopic studies since the hydro dynamic aspects of detonation and various performance crite ria of energetic materials are often covered adequately in other international meetings. An attempt was made to have a coherent presentation of various theoretical, computational and spectroscopic approaches to help a better understanding of energetic materials from a molecular point of view. The progress already made in these areas is such that structure property (e. g.
