"That's very sensible. They'd been working in Menegroth, making weapons for the war, for hundreds of years at that point and he'd always paid before. Anyway Thingol's people retaliated by slaughtering all the Dwarves in Menegroth, two survivors made it back to Tumunzahar, Tumunzahar sent out an army to try to retrieve any more survivors, ended up just laying waste to most of Doriath and taking the Silmaril for payment, Doriath sent a retaliatory force and killed most everyone in Tumunzahar and took the Silmaril back -
- we'd sworn to get the Silmarils from anyone who withheld them, because they were ours and we needed them. We wrote to Doriath offering to buy them. The messengers never returned. We attacked them."
