Per Ian's nomination statement: "Bill Anderson was one of the founding members of the Royal Australian Air Force. Among his claims to fame: sharing in the first aerial victory credited to No. 3 Squadron of the Australian Flying Corps in World War I; earning the first Distinguished Flying Cross awarded to an Australian; and serving the shortest term as Chief of the Air Staff (one month)...! [...] He appears to have been well liked but there's the suspicion that he gained his promotions and commands more through convenience and length of tenure than ability and sound judgement (surely not the only such officer!)"
This article covers an April 1863 battle fought during the American Civil War's Vicksburg campaign. As part of operations to bring Major-General Ulysses S. Grant's Army across the Mississippi seven US Navy ironclads attacked Confederate positions at Grand Gulf near Vicksburg. The attack was driven off, and Grant decided to cross the river elsewhere; he did so successfully the next day.
