8353. Your 6315. Expenditure of depth charges in all forces materially increased owing new depth charge policy, approved tactics provide laying barrage of 20 or 30 depth charges each attack. Refer Buord letter 32800 of 14 February 1918 paragraph 4. Urgently recommend daily output 125 mark 2 depth charges be at least doubled immediately if not already done, necessary establish stock of depth charges at various bases as recommended in my 7957, the possible loss of ship carrying large supply depth charges en route might seriously handicap successful prosecution of an[t]i-submarine campaign if sufficient stock is not maintained at each base. Supply of depth charges base 6 including shipments via BESOEKI and U.S.S. CULGOA will probably be completely exhausted June 15, recommend additional depth charges be shipped base 6 via U.S.S. GLACIER. As the number of United States Naval vessels in European Waters increases the supply of depth charges recommended for the various bases will have to be materially increased. 03024, 8353
