The passage begins with the gap between a U-boat force that could overwhelm a located convoy and one large enough to find and attack enough convoys across the Atlantic. The quoted 300,000 tons is then checked against broader Allied shipping-loss totals, distinguishing the drama of tonnage from the number of ships and the much larger wartime system. The comparison separates local operational intensity from the scale of the shipping network Britain's war effort had to sustain. An impressive statistic may be accurate while still giving a misleading sense of strategic effect when isolated from the surrounding campaign.
