About an hour later, a torpedo struck the Coast Guard cutter, and "Yukon" went to general quarters. About 30 minutes after that, the enemy submarine attacked "Yukon"; but her torpedo missed its mark, passing some astern. The cutter remained afloat for about a day before being sunk by American gunfire. "Yukon" arrived safely at Reykjavík, where she completed repairs before heading back to the United States. The ship resumed her voyages between the United States and American bases in the Atlantic, visiting such diverse places as Bermuda, Nova Scotia, Iceland, Trinidad, and Newfoundland.
