Another thing - all the devas had given all their weapons to Kartikeya, so how did they fight? In the story of Durga vs Mahishashur where they did that, it made sense, since other than Durga, nobody did any fighting, but here, how could the Devas have given their major weapons to Kartikeya and still had them available for battle? Another thing - the devas were great archers as well, particularly Indra, but he's always shown fighting w/ a sword.
