Jan Gralewski

Member of Polish resistance (Home Army) during World War II, he died in the controversial 1943 Gibraltar B-24 crash.

[7] On 4 July 1943, Gralewski most likely died in the 1943 Gibraltar B-24 crash, together with the Polish Prime Minister and commander-in-chief, Władysław Sikorski.

[3][6] Due to the controversy surrounding Sikorski's death,[8] some conspiracy theories surrounding this incident have raised questions regarding the role and fate of Gralewski in this incident, with suggestions by historians Dariusz Baliszewski and Tadeusz Kisielewski [pl] that he might have been shot by an assassin, and died ashore, not in the airplane crash, and that the assassin entered the airplane acting as his doppelganger.

His wife, who after the war became a sociologist in the United States, wrote about her belief that he was murdered as a part of an assassination plot in her 1987 book Niezdemobilizowani.

In late 2000s and early 2010s the Polish Institute of National Remembrance considered exhumation of Gralewski's body to address this issue, but eventually decided against it.
