Since Soviet help wasn't forthcoming and the uprising failed to liberate Warsaw, and it cost many Polish lives.
Well said. Whilst I'm sure you're aware of it, Gen. Okulicki (aka Bear Cub) provided a statement as to the reasons why the Rising was launched. It makes compelling (and I'd suggest compulsory, given its candour) reading and is an Appendix to Davies' Rising '44, or may be available online. I prefer his views to the fantasies postulated by some of our resident armchair experts.
Indubitably, a triumph of the spirit, relative to the circumstances. I can't recall who said it, but to borrow a phrase "To Poland, it was more important to play the game fairly than to win it". Modern day Poland is far removed from such romantic notions, but vis a vis tragedies of the past, which cannot be changed or rationalised, such sentiment provides solace and a hope that the sacrifice wasn't in vain.
