Hesiod, The Homeric Hymns, and Homerica
(ll. 224-251) But Reedy took to flight when he saw Ham-nibbler, and fled, plunging into the lake and throwing away his shield. Then blameless Pot-visitor killed Brewer and Water-larked killed the lord Ham-nibbler, striking him on the head with a pebble, so that his brains flowed out at his nostrils and the earth was bespattered with blood. Faultless Muck-coucher sprang upon Lick-platter and killed him with his spear and brought darkness upon his eyes: and Leeky saw it, and dragged Lick-platter by the foot, though he was dead, and choked him in the lake. But Crumb-snatcher was fighting to avenge his dead comrades, and hit Leeky before he reached the land; and he fell forward at the blow and his soul went down to Hades. And seeing this, the Cabbage-climber took a clod of mud and hurled it at the Mouse, plastering all his forehead and nearly blinding him. Thereat Crumb-snatcher was enraged and caught up in his strong hand a huge stone that lay upon the ground, a heavy burden for the soil: with that he hit Cabbage-climber below the knee and splintered his whole right shin, hurling him on his back in the dust. But Croakperson kept him off, and rushing at the Mouse in turn, hit him in the middle of the belly and drove the whole reed-spear into him, and as he drew the spear back to him with his strong hand, all his foe's bowels gushed out upon the ground.

(ll. 252-259) And when Leeky saw him fallen forward, but still half alive, he pressed through those who fought in front and hurled a sharp reed at him; but the point of the spear was stayed and did not break his shield. Then noble Rueful, like Ares himself, struck his flawless head-piece made of four pots—he only among the Frogs showed prowess in the throng. But when he saw the other rush at him, he did not stay to meet the stout-hearted hero but dived down to the depths of the lake.
(ll. 260-271) Now there was one among the Mice, Slice-snatcher, who excelled the rest, dear son of Gnawer the son of blameless Bread-stealer. He went to his house and bade his son take part in the war. This warrior threatened to destroy the race of Frogs utterly 3603, and splitting a chestnut-husk into two parts along the joint, put the two hollow pieces as armour on his paws: then straightway the Frogs were dismayed and all rushed down to the lake, and he would have made good his boast—for he had great strength—had not the Son of Cronos, the Father of men and gods, been quick to mark the thing and pitied the Frogs as they were perishing. He shook his head, and uttered this word:
