Progress west was slow, but, on 1 March, she set a course toward Holtz Bay to check for enemy shipping. The next day, heavy mist and fog hindered her reconnaissance of Stellar Cove; and she turned to the coastal shipping lanes to intercept enemy traffic between Cape Wrangell and Holtz Bay. The entrances to the latter, to Chichagof Harbor, and to Sarana Bay, however were her primary hunting grounds. On the night of 9 March, off Holtz Bay, she attacked and damaged an enemy destroyer, then underwent a brief depth charging. Leaks caused by the depth charging were minimized, and "S-32" continued her patrol.
