By decree of Wilhelm I (as head of state) on 4 July 1867, the Kriegsflagge (war ensign) of the North German League and the Kriegsgösch (jack) were established. By the Cabinet Order of 10 September 1867, effective 1 October 1867, these flags were flown by all North German (later German) naval ships. The jack consisted of the black-white-red national colors with (slightly biased towards hoist) a black Iron Cross (cotised white) 5/9 the height of the flag.
