"CINDERHEART!" Lionblaze screamed. In the thick of battle, he had lost his mate.
But let me explain everything from the beginning.
Shadowclan had invaded thunderclan territory, and they had almost reached the Camp when a ThunderClan patrol had found them and raised the alarm. Bramblestar, who led the patrol, told Cherrypaw to get others at the camp, and engaged the patrol in battle. The patrol, consisting of Bramblestar, Foxleap, and Sandstorm tried to hold them off until Cherrypaw came back, but they were forced to fall back and Bumblestripe, the guard, joined the fight. Just then, Cherrypaw came with Squirrelflight, Lionblaze, Ivypool, and Cinderheart. The nine cats then hurled themselves at the dozen Shadowclan cats.
A little time had passed but Thunderclan was losing. Cherrypaw was laying still, not moving. Sandstorm's ear was torn, and Foxleap had a huge gash on his flank, and was losing blood.
Only one ShadowClan cat - not one Lionblaze knew - had been driven off. And he couldn't see Cinderheart anywhere. Then he saw her. Time slowed down as he saw Cinderheart take a heavy blow to the head from Blackstar himself.
"No!" he screamed as he launched him self at Blackstar in a blind rage. When he returned to his senses he was pinning Blackstar down with one paw on his throat. He blinked and got off, but when Blackstar tried to get up he slammed into his flank, knocking him down again. He raked his claws against his belly, growling with anger.
Blackstar mumbled something that sounded like "Retreat." Then, he said it louder so his cats could hear it. They gave one last growl before leaving. Lionblaze glared at the ShadowClan leader with a hint of a snarl, getting off him and letting him go. Remembering Cinderheart, he whipped around and saw her body. She was breathing, but just. Bramblestar offered to help take her down to Jayfeather's den, but he ignored him and took her down to the medicine den. Mumbling "I love you.'
