I’d also hoped they’d have been able to punch through like Patton’s 3rd Army, but it wasn’t to be.A real shame as I'm sure people were still hoping that Ukraine would mount some kind of rescue counterattack to punch a hole through Russian lines towards Mariupol. It could have ended in either a success like Bastogne or a failure like Alesia (Gauls vs. Caesar), but it would have been worth a try, especially as Russians are retreating about everywhere else.
Either way, they occupied large amounts of Russian troops, inflicted high casualties, and fought one of the greatest last stands in modern military history.
