Why didn't Szpilman save captain Wilm Hosenfeld?

Why didn't Szpilman save captain Wilm Hosenfeld (he died in 1952)? If Szpilman finally found out his name he had about 8 years to do that (or at least to try to do that. Did he try really hard? Did he want to try hard?). I see at least a few potential explanations, but I prefer to hear first what do you think about it, or maybe even better you know the real reason (did Szpilman write something about it in his book?)?
