Siege of Takatenjin (1581)
The second siege of Takatenjin came only six years after Takeda Katsuyori took the fortress.
This second siege lasted from 1580 until 22 March 1581, and ended with deaths of 680 of Okabe Motonobu/Naganori's garrison.
Nobunaga sent Mori Nagahide to capture this fortress and the siege ended within four months. Okabe Motonobu died when he was attacked by Tokugawa forces under Honda Tadakatsu.
This was quite an advantageous event for Oda Nobunaga, as it weakened his enemies; the battle of Tenmokuzan the following year would come to be known as Takeda Katsuyori's last stand.
