Even success did not alter the conviction of Navy and Marine amphibious specialists that risks had been assumed in the Inchon landing which might have resulted in disaster. It was taking no credit away from General MacArthur for his unshakeable faith in victory to conclude that fortune had smiled in some instances when a frown would have been costly. The teamwork of Marine supporting arms was never shown to better effect than in the establishment of a bridgehead over the Han. Lieutenant Colonel Partridge’s engineers, of course, were on the job from the beginning. It was up to them to get the tanks across the river as soon as possible, in case the infantry needed the support of armor. Approaches and ferry landings had to be constructed for this purpose; and just six hours after the initial infantry crossing, the engineers had their first six-float M4A2 raft in operation. It had taken them four hours to build.[306] [306] 1st MarDiv _SAR_, Annex Nan Nan; Partridge interv, 23 Nov 54. The 2d Platoon of Able Company, 1st Tank Battalion, crossed the river at 1410 on 20 September and moved up in support of 3/5. The 1st Platoon followed at 1600 and the 3d Platoon late that afternoon, after the engineers completed a second raft. When the KMCs attempted to cross in DUKWs, the clumsy vehicles bogged down several yards from the river on the south bank. Partridge suggested to the KMC commander that his troops build a makeshift corduroy approach off the main route which Marine engineers were constructing to the embarkation point. The Korean officer agreed with Partridge that this was a sensible solution and soon had his men gathering logs. Neither of them dreamed that they had stirred up an international incident which called for a decision on the division level. American policy makers had felt it necessary to lean backwards to avoid giving Communist propagandists any excuse to charge us with recruiting Koreans for “slave labor.” It was an extremely sensitive subject, and Partridge was astonished at the repercussions. At last General Craig visited the ferry site and ruled that it was a closed incident after finding all explanations satisfactory. It was further decided--for mechanical rather than political reasons--to take the KMCs across in amtracs rather than waste any more time on DUKWs.[307] [307] Partridge interv, 23 Nov 54.
