Kenpuu Denki Berserk - episode 15 - 20 Jan, 1998

Griffith volunteers the Hawks to reclaim the impregnable Fortress of Doldrey from a Chuder governor named Gennon and the Purple Rhino Knights in his service. Guts learns that Griffith's unsavory history was with Gennon when he was a noble. The Hawks begin their assault before pulling back. Their boats are burned and there is nowhere to retreat to as the Chuder army leaves the fortress in pursuit. (Source: Wikipedia)
