Defense of the Coastal Corridor
Some elements of the 26th Division had arrived on Leyte during the naval battle, and on 1 November most of the 1st Division and the 12th Independent Infantry Regiment of the 26th Division landed at Ormoc. The 1st Division, which had been activated in Tokyo, had served in Manchuria during the “China Incident” and had been transferred to Shanghai in August 1944. Though it had no combat experience, this division was considered by General Tomochika to be the best equipped division of the Japanese Army. Under the command of Lt. Gen. Tadasu Kataoka, it had been held in reserve by Imperial General Headquarters for the decisive battle, and it was sent to Manila with great expectations.[10]
The arrival of these troops was in accord with a plan devised after the Battle of Leyte Gulf. The 102d Division, coming from Panay, and the 1st and 26th Divisions, sailing from Luzon, were to land at Ormoc. General Suzuki planned to have these troops move north along the Ormoc-Limon road (Highway 2) through Ormoc Valley, from which they were to diverge in three columns and capture the Carigara-Jaro road. After seizing the road, the Japanese troops were to advance east and destroy the American forces in the area between Tacloban and Tanauan. After the 1st Division had secured Carigara, the 68th Brigade was to land in the north as 35th Army reserve. At the same time the 30th Division was to land at Albuera on Ormoc Bay and advance over mountainous trails to Burauen and later neutralize all resistance in the Dulag area.[11]
When General Suzuki received information that the Americans had secured Carigara, he realized that it would be impossible to drive toward San Pedro Bay with the Americans on his left flank. He believed, however, that the reinforced 1st Division could easily wipe out the American forces in the Carigara area. On 3 November he ordered the 1st Division to speed up its passage through Ormoc Valley and the 102d Division to consolidate its forces with those of the 1st Division for an all-out attack to annihilate the American troops near Carigara. The 26th Division was to advance on Jaro.[12] No alternative to this plan had been prepared in case the projected operations were not successful.[13] On 3 November, American aircraft struck at the 1st Division as it moved up Ormoc Valley in a ten-mile-long convoy of trucks, tanks, and artillery. They destroyed about thirty trucks and left two tanks burning. The aircraft received heavy and accurate ground antiaircraft fire, and two of the planes were shot down by the Japanese.[14]
The lack of defense at Carigara had come as a surprise to General Krueger, since the Americans had observed the Japanese reinforcing the area. General Suzuki had cleverly concealed from the Americans his strength and intentions and thus had gained time for a withdrawal by a “very successful” delaying action.[15] At the same time, the 57th Infantry Regiment of the 1st Division had been able to move north through Ormoc Valley and establish itself in the northern mountains surrounding Highway 2.
The bringing in of reinforcements by the Japanese brought into sharp focus the lack of American aerial strength on Leyte. Although the Fifth Air Force had numerous aircraft in the rear areas, these could not be brought forward because of the very poor condition of the available airstrips. The few aircraft based on Leyte could not prevent the flow of additional enemy forces into the island or give direct support to the ground troops of Sixth Army.
Since the Japanese had been able to send without difficulty about 13,500 troops into the Ormoc area, General Krueger recognized that they were capable also of landing troops on the shores of Carigara Bay. This landing, if successful, would isolate the American forces in the Carigara area. To meet this threat, several courses of action were open to General Krueger: he could devote the full energy of the X Corps to preparing a defense against a sea force attack; he could disregard the threat and have the X Corps push vigorously south and secure a position on ground south of Limon, which was about two and a half miles southwest of Pinamopoan, before the Japanese could build defensive positions; or, finally, he could advance south with some elements, leaving others to guard the Carigara area.
If the Japanese Navy and amphibious assault forces entered Carigara Bay, the possibilities for effective countermeasures were not very promising. The escort carriers of the Seventh Fleet, greatly weakened by the Battle of Leyte Gulf, could not give support, and it was quite possible that any assistance that could be furnished by the Third Fleet might not arrive in time.
Ranking officers of the Seventh Fleet, however, did not believe it likely that the Japanese would launch an amphibious assault through Carigara Bay. The reasons given were as follows: The Japanese had never made an assault landing against defended beaches in the past; they were short of equipment to make a sustained amphibious assault; and they would be landing in the face of the combined fire of the X Corps artillery which would cover the beachhead area from positions well behind the beaches.[16]
Although General Krueger realized that the high ground in the Limon area was the key to operations farther south, he decided that the threat to the Carigara area could not be ignored. Since he had insufficient forces to drive south and at the same time to prepare the Carigara area for defense, on 4 November he directed General Sibert to protect the Carigara area from a seaborne attack before the advance to the south was continued. At the same time the X Corps was to send out units to explore for trails that led from Daro, about three miles southwest of Jaro, to Ormoc with the view of emplacing an artillery battalion of 155-mm. guns within effective firing range of Ormoc.[17]
