To Hakazin, the Battle of Calth was where that particular world was invaded by the Word Bearers at the start of the Horus Heresy. It rendered Calth what it is now, &, kind of like the Battle for Macragge, it was only won because Sergeant Thiel thought outside of the box. Or at least, he helped to win it because of his original tactics & ingenuity for communication methods. Basically, it was (as far as I am aware) the first time that an Ultramarine had done something that was not part of whatever battle doctrine they followed back then, & which is still something you hardly ever see among them these days.
