Note. The British Army was only marginally involved in the Battle of Caporetto. The remaining Royal Garrison Artillery Heavy Batteries and the support elements were caught up in the Italian retreat but managed to withdraw to safety more or less intact; one man died on the way and is buried near Udine. Also caught up in the melee were some British Red Cross personnel and volunteer aid workers, including GM Treveleyan, who wrote about the experience.

Notes

The Austro-Hungarian Army is referred to here as KuK; the abbreviation of Kaiserliche und Konigliche Heer, or Imperial and Royal Army, as the Emperor of Austria was also the Apostolic King of Hungary; in addition, there was not one but three armies; the Common, or Regular, Army; the Austrian Territorial Defence Force and the Honved, its Hungarian equivalent.

 The Italian GHQ was called the Commando Supremo, as, confusingly, was the head of the Army; CS is used here to denote either. The French equivalent was referred to here as the GQG, and the Austro-Hungarian one, the Armee Ober Kommando, is AOK, while the German Supreme Headquarters, the Oberste Heeresleitung is OHL. GHQ is used to refer to the HQ of the British Expeditionary Force (Italy), or BEF(I).
