Grumm Trenchler

Grumm Trenchler was a major character in the Redwall book Martin the Warrior. Grumm was a courageous mole and a friend of Rose of Noonvale. Grumm heard that her brother Brome was captured by Badrang, and so he set out to get Brome back from Marshank Fortress. Grumm dug right into the slave pit under the eyes of the enemy, aided by a clue from Brome, and Grumm found the slaves where Brome said they were. Grumm got them all out and he escaped with the others, noting with some despair that his side of the longboat was full of water and they were being chased by corsairs. However, Martin noted that the corsairs were having difficulty and were sinking. Grumm and the others soon realized they were free. Grumm got lost from the others and he ended up with Rose, and Grumm then became a prisoner in the pygmy shrew lair. Grumm was reunited with Martin and Rose and they freed Pallum from the shrews. Together they went North to the marshes and almost got eaten by the cannibal lizards but escaped with the help of the Warden of Marshwood Hill, a great heron, and they got to Boldred the owl's lair, but were chased by the savage Gawtrybe squirrels.

Boldred the owl saved them from the evil savages, and Grumm enlisted her help in fighting Badrang. The rebellion soon got underway and they returned to Fortress Marshank. There was a large battle and Grumm fought in it, killing many vermin but he was unable to stop Badrang killing Rose, his friend, and Martin killed Badrang in revenge. Grumm soon returned to Noonvale along with his friends.
