From 25 to 30 July, the Croatian Army and Croatian Defence Council (HVO) troops attacked Serb-held territory north of Mount Dinara, capturing Bosansko Grahovo and Glamoč during Operation Summer '95. That offensive paved the way for the military recapture of occupied territory around Knin, as it severed the last efficient resupply route between Banja Luka and Knin. On 4 August, Croatia started Operation Storm, with the aim of recapturing almost all of the occupied territory in Croatia, except for a comparatively small strip of land, located along the Danube, at a considerable distance from the bulk of the contested land. The offensive, involving 100,000 Croatian soldiers, was the largest single land battle fought in Europe since World War II. Operation Storm achieved its goals and was declared completed on 8 August.
