Final answer:
The references provided do not narrate a specific account of a boy named Heinrich of Netherwood. They offer historical events of World War II and the Holocaust, including the operations of Sir Nicholas Winton and the tragic realities faced by children during this time.
Step-by-step explanation:
The boy named Heinrich you mentioned seems to be a representation of a child during a tumultuous historical period. However, based on the multiple references provided, there is no direct narrative detailing what happened to a specific boy named Heinrich of Netherwood.
Instead, these references seem to be an amalgamation of stories and historical events from the period surrounding World War II, including the Kindertransport operations, the Holocaust, and the personal accounts of individuals such as Anne Frank and Sir Nicholas Winton.
From the information provided, which includes historical context relating to the Holocaust and the rescue efforts of Sir Nicholas Winton, it is understood that many children faced dire circumstances.
Heinrich Himmler's imposition of the Einsatzgruppen and the construction of extermination camps at Majdanek and Auschwitz led to mass murders of Jewish and other persecuted populations during the Holocaust.
The term "Heinrich of Netherwood" does not correspond to a specific historical figure or well-known narrative, so it is unclear exactly what happened to this boy without further details.
If the student is referring to a character in literature or a specific historical account, additional context would be necessary to provide an accurate answer.
