Misfortune struck again a few hours after Task Group 53.7 steamed from San Diego on 14 July. The transport _Henrico_ developed a serious mechanical failure and was declared temporarily unseaworthy. This ship was carrying Lieutenant Colonel Murray, his regimental staff, and the entire 1st Battalion Landing Team.[96] After Murray and his headquarters transferred to the APA _Pickaway_ off San Clemente island, the _Henrico_ limped back toward California with about one-third of the Brigade’s fighting force. The vessel docked at the United States Naval Supply Depot, Oakland, on the 16th. Repairs were started in urgent haste, since there was no other ship available. For security reasons, the Marines were forbidden to leave ship except for training on the dock. On the nights of the 16th and 17th, they sat on deck and gazed longingly at the beckoning lights of San Francisco. Twice during this time the _Henrico_ weighed anchor and passed westward under the Golden Gate bridge; twice it was forced to return for additional repairs. Finally, on the evening of the 18th, the vessel steamed under the great bridge for its third attempt. This time it kept going, but it would not overtake the convoy until the morning of the very day the ships reached their destination. [96] 1st Bn, 5th Marines, with supporting units. During the voyage, strict wartime security measures, including radio silence, were enforced on all ships. While the North Koreans were believed to have no warships left afloat, their naval capabilities remained hidden from the outside world by a blur of question marks. No one realized more than the commander of Task Group 53.7[97] that it was much too early to take Soviet Russia for granted. [97] Capt L. D. Sharp, Jr., USN. The _Henrico_, now travelling independently, had a spine-chilling experience during her second night out of Oakland. The ship’s radar picked up two “unidentified submarines” which appeared to be converging on the stern of the lone vessel. General Quarters was sounded. While sailors peered into the darkness from their battle stations, several hundred Marines joked weakly in the troop compartments below the waterline. After an anxious hour, the persistent spots on the electronic screen vanished. Shipboard life for the Brigade was otherwise uneventful. The troops took part in physical drills as vigorously as the limited confines of vessels would allow. Daily classes and conferences emphasized those subjects most relevant to the news reports trickling back from the front. Success of North Korean armor stimulated keen interest in land mines and the new rocket launchers. Press commentaries on the battleground’s primitive environment made even field sanitation a serious matter. Since there was no military intelligence available on the North Korean forces, officers and NCO’s turned to publications on Russian tactics and weapons.
