Upholder leads the scorecard with a claimed 21 vessels and 128,353 tons. Urge, Utmost, Unbeaten, Upright and the other boats follow, with possible claims kept separate from confirmed sinkings. The narrower period totals 390,660 tons even though the flotilla never fielded more than twelve submarines. Its targets included warships, transports, tankers, supply ships, schooners and a floating dock. The breakdown shows how much work a small force could do against several kinds of Axis shipping.
