version, there are three plain mouldings on the shaft near the base, often reduced to one in smaller sizes, and the three extremities of the cross finish at a plain moulding projecting sideways from the main element. The crossarms are sometimes irregular octagons in section, with four wide faces at front, back, top and bottom, and four shorter faces in between them. A stylized bronze longsword, point down, is fastened to the front of the cross. The cross is designed so that a second bronze sword may be fastened to the rear as well. The sword is positioned so that the crossguard on the sword matches where the cross's shaft and crossarm meet. The Cross of Sacrifice originally came in four heights: , , , and . Sizes up to are now permitted; exceptionally so too larger versions. As of 2012, the largest stands as the instance at the Halifax Memorial in Halifax, Nova Scotia, Canada. The shaft is fastened to an octagonal base. The size of the base varies, according to the height of the shaft, but the high cross has a base in diameter. This largest base weighs . The base usually sits on three octagonal steps. This can vary, however, depending on the height of the cross, its placement in the cemetery, and whether it is part of some other cemetery element. The position of the Cross of Sacrifice in Commonwealth war cemeteries varies depending on a wide range of factors. Many cemeteries were laid out haphazardly during the war. The role of the junior designing architect was to determine the position of the Cross (and Stone of Remembrance) in relationship to the graves. Most cemeteries had two axes—a main axis and an entrance axis, or a main/entrance axis and a lateral axis. An overriding guiding principle was that the War Stone should be the focus of the cemetery. The Cross of Sacrifice, however, usually functioned as the primary orienting feature of the cemetery for visitors, due to its height. In hilly areas, the architect had to ensure that the cross was visible from the road or path. (This was far less important in flat areas, obviously.) When a road passed directly by the cemetery, the cross usually was placed near the road and the entrance to the cemetery associated with the cross. These design considerations meant that the Cross of Sacrifice could be placed in a
