Brown in 1996 and Simpson in 2001 concluded that extending British supply routes over the ridge, which had been devastated by the mines and millions of shells, to consolidate the Oosttaverne line and completion of the infrastructure further north in the Fifth Army area, was necessary before the "Northern Operation" (the Third Battle of Ypres) could begin and was the main reason for the operational pause in June and July. In 1941 the Australian Official Historian recorded II Anzac Corps losses from 1–14 June as 4,978 casualties in the New Zealand Division, 3,379 casualties in the 3rd Australian Division and 2,677 casualties in the 4th Australian Division. Using figures from the Reichsarchiv, Bean recorded German casualties for 21–31 May, 1,963; 1–10 June, 19,923 (including 7,548 missing); 11–20 June, 5,501 and 21–30 June, 1,773. In volume XII of Der Weltkrieg the German Official Historians recorded 25,000 casualties for the period 21 May – 10 June including 10,000 missing of whom 7,200 were reported as taken prisoner by the British. Losses of the British were recorded as 25,000 casualties and a further 3,000 missing from 18 May – 14 June. The initial explosion of the mines, in particular the mine that created the Lone Tree Crater, accounts for the high number of casualties and missing from 1–10 June. In 1948, the British Official Historian gave casualties of II Anzac Corps, 12,391; IX Corps, 5,263; X Corps, 6,597; II Corps, 108 and VIII Corps, 203 a total of 24,562 casualties from 1–12 June. The 25th Division history gave 3,052 casualties and the 47th Division history notes 2,303 casualties. The British Official Historian recorded 21,886 German casualties, including 7,548 missing, from 21 May – 10 June, using strength returns from groups Ypern, Wijtschate and Lille in the German Official History, then wrote that 30 percent should be added for wounded likely to return to duty within a reasonable time, since they were "omitted" in the German Official History, reasoning which has been severely criticised ever since.
