The Transit to Manila
To cover the transportation of the troops to the Philippines, in fear of a more pronounced Japanese naval presence in that theatre, the Navy ordered several fleets from Kiska to Hawaii to be sent as cover for the force. Not since the opening days of the war, with the sea battles around Hawaii and off the California coast, had the American fleet met any serious resistance. It gave a false hope to the admirals no doubt, but Secretary of the Navy William Standley knew the Japanese navy was far more powerful than that, with the vast majority of its bite left. He knew that the bulk of the Japanese navy was out there still, probably protecting the waters closer to home, but exactly where it was, what its mission was and how large it was were the questions that troubled him most, forcing him to gather a large host of capital ships from several ports to help cover the transport fleet on its way to the Philippines. The second phase of the operation for the navy, once the troops were landed would be to guard the shores from Japanese invasion.
Despite the risky trip through the Japanese held waters, the convoy fleet successfully navigated the waters between Guam and the Carolinas. Without so much as a single Japanese ship sighted in the areas, the confidence increased as the Philippines neared. Like the landing in the Kurils, the troops disembarked onto the eastern beaches without a hitch or shot fired. To say the least, General Simpson commanding the 370th on the island since before the outbreak of war, was quite glad to see his fellow Americans coming ashore to aid him. The Philippines were so very far from home, and so very cut off from it. With the landings completed successfully, the troops were reassigned around the perimeter of the city and beaches.
Patton and Clarkson met with Simpson and the Philippine generals to lay out the best plan for defense, choosing to integrate the two forces into one combined command. To the south on Mindinao, the Japanese force, collectively known as the Fourteenth Army under General Hanada, was comprised of up to six divisions, the exact makeup at the time was unknown. Air strikes were ordered for the newly arrived tactical wing fresh from the states, to get a better idea of the force dispositions and makeup. It was agreed upon by the Generals for the time being to hold the line from Manila to the north, in effect grouping the forces together to prevent being overpowered by a large invasion force. With the first step of the mission complete, Sherman's now empty transport fleet was ordered back to Wake, while the other naval forces began to close around the northern and eastern half of the island to protect it from invasion.
The Naval Battles of the Philippines
The staff at Pacific Navy HQ in Hawaii were quite busy at this time, pushing and relocating many ship units across the board, as unit after unit were being sent to the Philippine theatre. It was quite a cluttered mess really, with units ranging from single destroyers to entire fleets setting sail for the general Philippine theatre, without so much organization as to be able to coordinate and support one another. Once the fleets were in place around the island, then they would be drawn up into more cohesive units, and given proper theaters of operations off each coast. Very soon the majority of the fleets sent to the theatre had arrived, or were arriving when the first contact with the Japanese Navy began.
Mitscher's 5th Cruiser fleet was brought down from the northern pacific for coastal duty in the northern Philippines and the timing could not have been more perfect. Their main mission being to prevent a proper Japanese landing force from getting ashore, their purpose was realized just as they arrived in the area. A seventeen ship fleet of mostly convoys was intercepted off the shores of Manila, apparently meant for a massive invasion. The guns were let loose, and fire reigned down on the Japanese ships. After quite a bit of damage was done to them they were sent fleeing.
However, two days later in the West Philippine Sea William Standley's nightmare of what the Japanese Fleet might be made of came to light. Mitscher's fleet was assailed by an absolutely massive fleet under the much feared Admiral Yamamoto. The pilots on reconnaissance flights merely radioed back words of great disbelief at the sheer size of the armada. Coming at the American fleet broadside, it let loose a hail of fire from its many battleships and cruisers. The 5th Cruiser Fleet was simply outnumbered, outmatched and outgunned. A very lopsided battle which did considerable damage to the main of the fleet, several ships were quickly sunk, while the bulk of the force withdrew under cover of night, most ships severely damaged. Mitscher realizing just how much damage his ships had taken ordered a full retreat, and the wounded fleet, much smaller in size than a day before, was sent limping back to Wake Island for repairs.
The Second Strike
After having dropped off the troops on the island, Sherman's 5th Transport Fleet had set sail to return to Wake to began planning for the loading of more reinforcements. To the southeast of the battle that had just transpired, on the following morning to Sherman's horror, that same immense fleet making incredible speed soon caught the transport fleet in its sights. As on the previous days the massive guns of the Japanese battleships and immense firepower afforded by the sheer size of the fleet ripped through the lightly defended transport fleet and decimated its ranks. It was a second day of woeful losses for the American navy, and under cover of night the ships remaining afloat were ordered withdrawn "at all speed" to Wake for repairs. In anticipation of engagements with the Japanese Navy in the Philippine theatre, Wake was set up to anticipate an increased need for ship repair, with many men being sent from the San Francisco and Pearl Harbor docks for that purpose. They simply had no idea there would be this many ships headed this way looking for repairs. The docks at Wake would become the busiest area in the entire American military over the next few weeks. Overburdened, those ships that were in the best shape were transferred instead to Pearl Harbor, as Wake was just unable to service this many ships at once.
The Third Strike
With unprecedented speed and awareness of the American fleet dispositions, Yamamoto's work was not done. Reconnaissance flights having picked up the largest of the American navies, Kimmel's 4th Fleet off the east coast of Manila, the massive armada move with all speed to destroy it. For reasons not entirely known, Kimmel's 4th fleet despite knowledge of the two naval battles in the waters to the north over the previous three days, was completely unprepared for battle. Disorganized and still drawing up its formation for coastal defense, it had simply not anticipated being attack by such a large fleet so quickly. And Kimmel had simply not considered that a Japanese fleet of that size could have moved so quickly after two successive battles.
Simply put the 4th Fleet was assailed and ambushed upon the first rays of dawn. A low hanging fog in the early morning hours prevented the two fleets from realizing the other was there. The difference was that the 4th Fleet wasn't expecting a fight and was not manning its guns, while the entire of Yamamoto's force had been moving in during the night with full knowledge of the 4th Fleets location, guns fully trained and ready for when the forces would meet. The 4th Fleet's positioning could not have been worse for the initial engagement. The first they realized of the Japanese Fleet's arrival was the sound of countless guns firing at them broadside. By time battle stations were ordered, several capital ships were engulfed in large black clouds of oil fire. Several ships, cruisers and battleships among them were sunk within the first 15 minutes of the fray.
Having sent a second smaller force farther out in the sea in a flanking maneuver, this 2nd Japanese group now moved in from the east, and the 4th Fleet was taking fire from two sides. Before Kimmel could even coordinate his ships in a firm battle plan, most of his ships were damaged beyond repair or sunk as the immense Japanese fleet of over 50 ships hit the 4th Fleet like a tsunami. Completely overpowered and outgunned, as well as outfoxed and unprepared, the bulk of the 4th Fleet was sent to the ocean floor within four hours. The last ship standing, that being the USS Saratoga was finally sunk by torpedoes at 4pm, July 19th. In a mere week, the majority of the United States navy in the Philippines had been sunk or put out of action by Yamamoto. It was very simply the worst naval defeat in United States History. For the second time in a month, the military had been served a crushing defeat, first on land in the Kurils and now at sea in the Philippines.
