This is revised and updated version of Chris Dunning's since long time sold-out "Courage Alone" from 1998. The new edition includes many new images but so far I haven't found any new information (I haven't gone through all unit histories yet). The book covers every Gruppo and Autonomo Squadriglia histories, areas of operations, allocations, OOBs, aircraft types etc. Two new things in the book are two appendices with extracts from the technical manuals for the Ca.310 and CR.32 (not adding very much). It also list the Regia Aeronautica aces (which still unfortunately includes the error that Franco Lucchini (http://surfcity.kund.dalnet.se/italy_lucchini.htm) claimed five victories in Spain - in fact he only claimed an I-15 as a solo victory on 21/02/38. It is still the best reference source on the Regia Aeronautica available in English but if you have the first edition, there is no need to buy this version (if you're not like me, who wants to buy everything available on Italian aviation, that is...). However, if you don't have the previous edition and is the slightest interested in the Regia Aeronautica, this is definitively a must! Highly recommended!
