(can I badly wound Longfur?)

(Of course. It's not like he expects to escape severe injury here.)

Hawk

Hawk slashes Longfur on his face. Then he bit Longfur, hard, and rips out some of his fur.

The slash across the face barely seems to faze Longfur, and the lost fur only angers him as he hisses, "Do you think that will stop me, BloodClan filth?"
He lunges forward, and Los loner leg trips him, leaving him flat on his belly. He had been goin for your throat.

Hawk

Hawk jumps behind Longfur, and rips out part of his tail (yeaaaah he's really aggresive).

Longfur
Longfur scrambles to his feet, and this time lunges successfully, touching deep claw marks across Hawk's face, barely missing an eye.

Shadowstar
Shadowstar and Terror were charging through the territory, closing on Carrionplace.

Hawk

Hawk slashes Longfur's throat.

Longfur
Longfur stiffens for a moment, then, knowing he is dying, throws himself on Hawk, fastening his teeth around the larger cat's spine, but is too weak to kill him.

Shadowstar and Terror
Shadowstar and Terror come into view just in time to see their son's throat slit, and charge in. Just as longfur goes limp, Terror barels into Hawk, while Shadowstar slips underneath, bringing his reinforced claws up between Hawk's hind legs, intending upon causing as much pain as possible to this cat that killed their only kit.
(You just killed ShadowClan's only full Medicine Cat. Congratulations on crippling a whole Clan.)

Hawk

Hawk looks at the two cats. He looked at the small black tabby, knowing he was the Leader. He gets ready to aim for Shadowstar's eye. (you can decide if Shadowstar loses a eye)

Shadowstar crouches under it, and lunges, both sets of claws cutting deep into Hawn's face. Then Terror bites down on his spine and crushes it easily.
She keeps her grip as she begins clawing at him rapidly gutting him.
