From Halopedia, the Halo wiki
Fighter's Blood, along with Hammerstrike, were destroyed during the Carrow Conflict after Hekabe's forces turned on Thars 'Sarov. One of Hekabe's Jiralhanae, Anexus, suggested they send Foebane to rescue survivors and salvage weapons. Hekabe refused, saying they would need Foebane for transport soon.
