But to return for a time to the means taken to attract the notice of other ships. The wireless operators were now in touch with several ships, and calling to them to come quickly for the water was pouring in and the Titanic beginning to go down by the head. Bride testified that the first reply received was from a German boat, the Frankfurt, which was: "All right: stand by," but not giving her position. From comparison of the strength of signals received from the Frankfurt and from other boats, the operators estimated the Frankfurt was the nearest; but subsequent events proved that this was not so. She was, in fact, one hundred and forty miles away and arrived at 10.50 A.M. next morning, when the Carpathia had left with the rescued. The next reply was from the Carpathia, fifty-eight miles away on the outbound route to the Mediterranean, and it was a prompt and welcome one--"Coming hard," followed by the position. Then followed the Olympic, and with her they talked for some time, but she was five hundred and sixty miles away on the southern route, too far to be of any immediate help. At the speed of 23 knots she would expect to be up about 1 P.M. next day, and this was about the time that those in boat 13 had calculated. We had always assumed in the boat that the stokers who gave this information had it from one of the officers before they left; but in the absence of any knowledge of the much nearer ship, the Carpathia, it is more probable that they knew in a general way where the sister ship, the Olympic, should be, and had made a rough calculation. Other ships in touch by wireless were the Mount Temple, fifty miles; the Birma, one hundred miles; the Parisian, one hundred and fifty miles; the Virginian, one hundred and fifty miles; and the Baltic, three hundred miles. But closer than any of these--closer even than the Carpathia--were two ships: the Californian, less than twenty miles away, with the wireless operator off duty and unable to catch the "C.Q.D." signal which was now making the air for many miles around quiver in its appeal for help--immediate, urgent help--for the hundreds of people who stood on the Titanic's deck.
