On the night of November 29, 1939, the boat left Kronstadt and went on combat alert to position No. 17 near the island of Foret north-east of Gotland to monitor the Swedish ships and carry out a long blockade of Finland. During the first few days of patrolling, within sight of the Sch-309, only German steamships passed through without inspection. On December 2, a Swedish warship converted from a fishing vessel proceeded through the boat’s position. On December 5, the boat received an order to proceed to the base in Tallinn . On December 6, “Dolphin” arrived in Tallinn, and on December 12, having not had time to undergo post-post repairs, it was relocated to Libau .
On December 14, “Щ-309” was sent to block the sea communications at position No. 8 southeast of the Aland Islands . As a result of bad weather conditions (temperature up to −30 ° C and stormy weather), at the time of arrival at the position, the boat was very icy. Under the weight of the frozen ice, the antennas broke, the antenna racks broke. Waves twice washed away from the boat sailors chopping ice. With great difficulty they were lifted aboard. On January 17, the command gave permission to return to Tallinn due to the inability to continue patrolling due to the weather. After the end of this extremely difficult campaign, the commander of the "Dolphin" S. S. Veselov developed an acute gastric disease, which did not aggravate earlier. Soon, due to health reasons, Veselov was decommissioned from the submarine fleet and was appointed captain of the Smolny submarine base. The post of commander of the "Щ-309" was taken by I. S. Cabo , who commanded the submarine " M-81 " before that.
