Having spent much of May training around Camisino, the 2nd
Battalion returned to the heights of the Asiago Plateau at the end of the month for a short tour, before once again descending to the plains where they were reviewed by the King of Italy on 7th
June, a major Austrian attack, which penetrated the British front, caused the HAC to be stood too as a reserve. But the front was restored within 48 hours, and the battalion was not needed. The month, however, ended unhappily when, once more in the line, a diversionary patrol was caught in short range machine gun fire with the entire section being killed, wounded or captured.
In France there was something of a (relative) lull between the last German offensive at the end of April and the beginning of the final 100 days on 8th
August. The Siege Battery spent the month of May in reserve, though under sporadic long range harassing fire, and the month of June in the line in support of Australian and American troops. 2/A and 2/B Batteries likewise spent the period in what were described as offensive/defence activities.
In Palestine, A and B batteries had been engaged in a major action on the River Jordan in early May, fighting a Turkish counterattack in which a gun was lost before the enemy was held and the position restored. Following this surge of activity the front went quiet and the batteries spent much of May and June 1918 sweltering in the Jordan Valley as, contrary to local usage, the allied forces held their ground in the valley bottom for the hottest part of the year.
