Letter with a black stamp from Oda Nobunaga to Hashiba Hideyoshi

This letter was sent by Oda Nobunaga to Hashiba Hideyoshi when Hideyoshi attacked Tottori Castle. Hideyoshi, lord of Nagahama Castle, was ordered to conquer the Chugoku region, which was ruled by the Mori clan. In 1581, Hideyoshi attacked Tottori Castle, which was defended by Kikkawa Tsuneie. Hideyoshi chose to starve out the castle in an extremely gruesome strategy which resulted in people inside starving to death. In the letter, Nobunaga states that death by starvation was a divine punishment, that he was sending Akechi Mitsuhide along with reinforcements, and that he personally would also be coming.
