		23 Aug 1943	0300	45° 12'N, 32° 30'E (0) Approximately.	At 0300 hours, a torpedo missed CB 1. It was probably fired by the same submarine (SC-203) attacked and sunk by CB 4 a half hour later. In 1949, the wreck of SC-203 was located. Her no. 1 and no. 4 tubes were found empty and speculation was made that she fired them at CB 1.

		15 Sep 1943	2145 (e)	(0) South of Cape Sarych.	At 2145 hours, three enemy vessels were sighted at a range of about 1,000 meters, steering west, speed 6-7 knots. One was a barge or very flat vessel, about 20 metres in length without any superstructure and believed to be carrying ammunition. Four men in rubber suits could be observed on board. The other two vessels seemed to be escorting gunboats. CB 1 fired a single torpedo at a very close range aimed at the barge. It was claimed sunk but the proximity of the explosion of the midget's own torpedo damaged her, causing the breakdown of the engine and a leak aft. Both the gunboats made off, dropping a few depth charges. Apparently the purpose of the Soviet operation was to land agents behind enemy lines.
