What fiction or fantasy battle deserves a Sabaton song?

As a 40k fan, there are so many good ones (as comes as a surprise to no one). Some personal favorites of mine are:

• Anything from the 3rd war for Armageddon
• The battle of Hellsreach
• The invasion of Rin's world
• Istvan V dropsite massacre
• And of course the fall of Cadia
