Raid on Corsin

"Spacers' tales told of massive Mandalorian war fleets lurking in the dark beyond the Rim, but for a decade the Republic did little but watch and wait, even as Neo-Crusader raids imperiled worlds from Corsin to Azure"

- From Vilnau Teupt's "Industry, Honor, Savagery: Shaping the Mandalorian Soul", 24 ABY

Mandalorian Neo-Crusaders once 'raided the planet of Corsin. Before Mandalorians directly harassed the Galactic Republic's forces in 3,965 BBY, they raided systems outside the Republic's territory. This went on for most of a decade after they devastated the planet of Cathar in 3,973 BBY, and during this time they attacked Corsin.

In 24 ABY, Vilnau Teupt delivered the keynote address at the four-hundred-twelfth Proceedings of Galactic Anthropology and History, in which he spoke on the Mandalorian race's development, mentioned the raiding of Corsin during his overview of the Mandalorian War.
