What are some interesting Warhammer 40k Black Crusade stories?

A memorable story is about a Chaos Lord who decides to lead his warband on a suicidal mission during the Black Crusade. His goal is to take over a heavily fortified Imperial stronghold. Against all odds, they manage to break through the defenses.
