Lieutenants Viljo Iisalo (1914-1983), Tauno Iisalo (1916-1947), Aulis Iisalo (1918-2007) and Cadet Pentti Iisalo (1920-2008) photographed in their mother's funerals in July 1942. Exceptionally two brothers, Pentti (in 1941) and Tauno (in 1944) were awarded with the Mannerheim Cross and Aulis was also a nominee for the cross. Note that Viljo still has his arm in "package" after it was torn by exploding bullet six months earlier, so badly that it was close to being amputated.
