45th HAG had been supporting the Anzacs in their attacks at Pozières, but the BEF was preparing for a new phase of the Somme offensive (the Battle of Flers-Courcelette). 94th Siege Bty was ordered to go 'into action' at once. It spent two days preparing a position on the western edge of Contalmaison, which had just been captured, but this was unsuitable, so the two guns of Right Section (RX) were mounted on 25 August behind the ruins of La Boisselle Church. On 3 September, Left Section (LX) moved into an exposed advanced position in 'Spring Gardens', a sunken road connecting Ovillers with the main Albert–Pozières road. It was while preparing these positions that the battery suffered its first casualties killed in action by shellfire.
