CHAPTER TEN
The Squadron Complete
After a conference with the commanding officers with the various incidents of the first excursion fresh in mind, revised instructions applying equally to every excursion were drawn up, to be supplemented by the particulars for each successive occasion issued at the appropriate time. The term excursion met with ready adoption, for its cheerful suggestion of a return—weary no doubt, but content.
A navigation memorandum of the intended courses, speeds, and principal incidents, for the information of the escort leader and each ship, accompanied the excursion order. An excellent understanding, as well as good feeling, grew up between the squadron and its escort. The escort commander would often dine on board the San Francisco and discuss the coming excursion and the two bodies soon came to move as one, changing course, night or day, or changing formation, frequently with only a whistle blast—a whole excursion sometimes without any tactical signal at all between the two bodies, except for some unforeseen change of course or speed.
Preparations had begun at once for the second excursion to continue the first minefield, but change had become necessary, and a line across Area C was ordered—not, however, until Roanoke had been loaded with 830 mines of an adjustment not suited to the changed plan, and these remained on board 33 days, the crew living around, but keeping up cleanliness and order the same as usual. So long a period fully loaded had not been contemplated, but it showed one more thing these vessels could do when well manned and commanded.
As before, assembly was at night 30 June, and Udsire the point of final departure. The supporting force was the 6th Battle Squadron of five American battleships under Rear Admiral Hugh Rodman, U.S.N. Needless to say, every one came on deck to see our handsome battle squadron, as it filed out past Pentland Skerries and formed line, disappearing to the southeastward. Twice during the afternoon submarine periscopes were seen by the battleships and their destroyer screen, which opened fire and dropped depth bombs, but without known effect.
Considerable current was found near the Norwegian coast, but visibility was good until we passed to the northward of Udsire; then it became increasingly hazy. The run of the flagship, guiding, was accurately determined notwithstanding, by other marks to the northward before they too became indistinct. At 4.26 a.m., minelaying began—great care taken not to lay any mines inside Norwegian waters, yet to begin just outside them. Despite the unexpected strong current at the critical moment, the first mines were dropped within 250 yards of the intended spot, just outside the three-mile limit.
Overcast sky prevented obtaining good observations to check the run during the minelaying, and as there was no check on latitude and the current was variable, the course was changed slightly for the last third of the run, to be sure of clearing our first field, towards which we were heading. This accounts for the bend in that line on the chart. We were crossing the 150-fathom deep water which skirts the Norway coast, three large ships, Canonicus, Canandaigua, and Housatonic, led by San Francisco, laying 2200 mines in two rows on a line 46 miles long. In spite of repeated breaking of the distance-measuring taut wire, the speed over ground was estimated closely enough to end the line within one-half mile of the point intended, which was correct within 1 per cent.
