Why We Fight - S1-E9
Corrected entry: John A. Janovec, an American soldier is shown in this and the last episode. As shown in the titles, this episode takes place from March 11 to sometime in late April. Yet, John A. Janovec died on February 26, 1945.
Correction: Online sources claim two different death dates for Janovec, some the February date that you cite, others the May date as depicted in the show. As the book and TV series are specifically based on the recollections of those who were present at the time, as recounted in many interviews, both with the original author and subsequently the film crews, it seems reasonable to suggest that the May date is likely to be the more accurate one, particularly as Janovec's death, so late in the war and after the end of hostilities, would be likely to stick in the mind.

I've read the extremely well detailed and informative book by Ambrose about Easy Company and there's no mention of an early 1945 death of Janovec at all so the latter date is more likely. The original men who gave accounts never mentioned his death and the place where he was eventually killed fits in with the units timeline history.
