How Cossack coordinated a dispersed night attack

Who coordinated the box formation, and how was control maintained at night?

Cossack coordinated, but extensive training and delegated judgment let each destroyer operate with minimal signalling that might reveal its position.

Cossack coordinates the formation, but command cannot be micromanaged in darkness. Radio or flashing-light traffic risks exposing positions, so subordinate commanders must act from shared doctrine and their own judgment. The arrangement is a practical example of light-touch, or mission, command at sea.
