Each of the six increments had its own time schedule for an independent voyage. The route to Inchon was marked off on maps by a chain of check points, the most significant of which bore the code names ARKANSAS, IOWA, and CALIFORNIA. The first two, lying in the East China Sea off the southwestern tip of Korea, formed the junction of the sea lanes from Japan and Pusan. Consequently, there was no alternative to their remaining fixed in the direct path of the oncoming typhoon. Point CALIFORNIA was important in that it marked the end of the open sea phase and the beginning of the treacherous offshore approach to Inchon via Flying Fish and East channels.[116] [116] ComPhibGru-1, _OpOrder 14-50_, Annex Dog. [Illustration: MOVEMENT TO THE OBJECTIVE AREA] The departure schedule for the Attack Force was set out in Doyle’s Operation Order 14-50 as follows: ------------------------------------------------------+--------+------ Unit | Port | Date ------------------------------------------------------+--------+------ Pontoon Movement Group (2 ATFs, 3 LSUs, 1 YTB, 1 YW) |Yokohama| 5 Sep LSMR Movement Element (3 LSMRs) | do | 9 Sep Tractor Movement Element A (LSM, 1 AMS, 1 AM, 1 ARS, 2| | LSDs, 36 LSTs) |Kobe |10 Sep Tractor Movement Element B (1 ARL, 1 PF, 1 PCEC, | | 12 LSTs) | do |10 Sep Transport Movement Group (5 APAs, 8 AKAs, 1 AP, 2 PFs)| do |12 Sep Advance Attack Group (Wolmi-do) (1 LSD, 3 APDs) |Pusan |13 Sep ------------------------------------------------------+--------+------ The chart shows the basic pattern, which would evolve only after considerable shuffling and secondary routing. For instance, two vessels of the cumbersome Pontoon Movement Group, carrying vital equipment for the expansion of Inchon’s port facilities, would not leave Sasebo until 11 September. They were to join the slow Yokohama convoy near Point IOWA the same day. Tractor Elements A and B, the latter trailing at a distance of six miles, would pick up the Pusan LSTs at IOWA on 13 September. The Kobe contingent of the Transport Movement Group was to pass through Point ARKANSAS on the 14th, joining the _Cavalier_, _Pickaway_, _Henrico_, and _Seminole_ from Pusan.
