In a conference held aboard our tender before reaching the American coast, I arranged that U-40 should attack the submarines and destroyers; that U-41 should torpedo the caisson gate of drydock A; and that U-42 should destroy the gate of drydock B. Each boat was to do such other damage as the conditions would permit. U-40 and U-41 were to enter in line ahead, and make the circuit of the basin; U-42 was to back in and take position in the middle of the basin.
