The Siege of Terabe took place in 1558.

This was the first battle that Tokugawa Ieyasu was involved in. At the time, he was a vassal of Imagawa Yoshimoto.

Suzuki Shigeteru, in charge of Terabe Castle, dumped Imagawa for Oda Nobunaga. Ieyasu attacked the castle, but was driven off by reinforcements sent by Nobunaga.
