co-operate

— On Friday, 14 September–the same day on which the Chinese convoy with the reinforcements for Manchuria left Taku–Ito had completed his work in connection with the transport of Japanese troops, having landed the last detachments at Chinampo in the estuary of the Ta-tung River. Higher up the river General Nodzu's army was attaching the Chinese walled town of Ping-yang. Ito sent his gunboats up the Ta-tung to co-operate with Nodzu, and leaving his torpedo boats at the river mouth, went to sea with his fleet.
