7th Cavalry Regiment
WW II, Pacific
"The Seventh First"





Captured Japanese Pilot's View
  
On 07 December 1941, without warning, the Japanese destroyed the American fleet at Pearl Harbor. Although the 1st Cavalry Division was created as a result of a proven need for large horse-mounted formations, by 1940 many thought that the march of progress had left the horse far behind. All doubt was erased with the surprise of the Japanese attack on Pearl Harbor. Immediately troopers returned to the 1st Cavalry Division from all over the United States. They outfitted their horses and readied their weapons and vehicles in anticipation of the fight against the Axis.

In February 1943, the entire 1st Cavalry Division was alerted for an overseas assignment as a dismounted unit. An impatient 1st Cavalry Division was dismounted and they were processed for movement to the Southwest Pacific theater as foot solders. In mid June 1943, the last troops of the division departed Fort Bliss, Texas for Camp Stoneman, California and later on 03 July, boarded the "SS Monterey and the SS George Washington" for Australia and the Southwest Pacific.

On 26 July, three weeks later, the division arrived at Brisbane and began a fifteen mile trip to their new temporary home, Camp Strathpine, Queensland, Australia. The division received six months of intense combat jungle warfare training at Camp Strathpine in the wilds of scenic Queensland and amphibious training at nearby Moreton Bay. In January 1944 the division was ordered to leave Australia and sail to Oro Bay, New Guinea. After a period of staging in New Guinea, it was time for the 1st Cavalry Division to receive their first baptism of fire.

Island Combat
  
On 27 February, Task Force "Brewer", consisting of 1,026 troopers, embarked from Cape Sudest, Oro Bay, New Guinea under the command of Brigadier General William C. Chase. Their destination was a remote, Japanese occupied island of the Admiralties, Los Negros, where they were to make a reconnaissance of force and if feasible, capture Momote Airdrome and secure a beachhead for the reinforcements that would follow.

Just after 8:00 on 29 February, the 1st Cavalry troopers climbed down the nets of the APD's and into the LCM's and LCPR's, the flat bottomed landing craft of the Navy. The landing at Hayane Harbor took the Japanese by surprise. The first three waves of the assault troops from the 2nd Squadron, 5th Regiment reached the beach virtually unscathed. The fourth wave was less lucky. By then. the Japanese had been able to readjust their guns to fire lower and some casualties were suffered. At 8:00 hours 04 March 1944, 7th Regiment, as a part of the combat reinforcements of the Admiralty Campaign landed, unopposed, in the Los Negros Islands at the northeast corner of the Momote Airdome. Their first significant resistance was encountered on 05 March. By 10 - 11 March, mop up operations were underway all over the northern half of Los Negros Island and attention was being given to a much bigger objective immediately to the west; Manus Island.

The First Wave
  
The Manus Island invasion commenced at dawn 15 March, with heavy shelling, naval bombardment and air attacks. Soon afterward, the 2nd Brigade, under the command of Brigadier General Verne D. Mudge, surprised the enemy by swarming ashore at two beaches near the Lugos Mission Plantation. By dusk the 1st Squadron of the 8th Cavalry regiment had advanced past snipers and scattered resistance and dug in on the western edge of Lorengau Airdrome, the last airfield controlled by the Japanese. 16 March was a day of heros - and casualties - as troopers charged or crawled through heavy machine gun fire to wipe out the enemy positions. Lorengau Airdome was captured the next day, after the 7th Cavalry moved up to relieve the weary 8th Cavalry fighters.

On 18 March, the 2nd Brigade crossed the river in force and drove the enemy from Lorengau Village. The objectives were Rossum, a small village south of Lorengau and Salsia Plantation. By 21 March, the 8th Cavalry had won control of most of the plantation, but the battle for Rossum was slowed by heavy jungle which the Japanese used to their advantage. After 96 hours of bitter combat the 1st Squadron, 7th Cavalry was relieved by the 1st Squadron, 8th Cavalry. The final push to Rossum was made behind heavy artillery fire and air bombardment. On 28 March, the battle for Los Negros and Manus was over, except for mopping up operations.

The Admiralty Islands campaign officially ended on 18 May 1944. Japanese casualties stood at 3,317 killed. The losses of the 7th Cavalry Regiment included 43 dead, 17 wounded and 7 died of non battle injuries. Training, discipline, determination and ingenuity had won over suicidal attacks. The 7th Cavalry Troopers were now seasoned veterans.

Return to the Philippines
  
After a period of 5 months in rehabilitation and extensive combat training, the 7th Cavalry Regiment received instructions on 25 September, to prepare for future combat operations. On 20 October, the regiment began the assault of Leyte Island. The first wave landed at White Beach at 10:00. The 7th Cavalry was assigned the mission of securing the Taeloban Airstrip. During the Leyte Campaign, the regiment suffered 52 killed, 204 wounded while inflecting 1,390 losses on the enemy. On 02 January 1945, the evacuation of Villaba began. Upon arrival in Tunga, the entire regiment devoted its time to establishing a camp, re-equipping and rehabilitation.

With the last of the strongholds eliminated, the division moved on to Luzon, the main island of the Philippines. On 26 January, conveys were formed and departed for the Lingayan Gulf, Luzon Island, the Philippines. Landing without incident on 27 January, the regiment assembled in an area near Guimba and prepared for operations in the south and southwest areas. From 23 February to 11 March, the entire regiment concentrated in breaking the strongly held Japanese line west of Antipolo. 02 April, second phase of the Luzon Campaign began. On 28 July, the final elements of the regiment closed in Sariaya and the Luzon Campaign was officially ended at 2400 hours on 30 June. The regiment suffered 145 killed, 37 died of wounds, 603 wounded and 2 were reported missing while inflicting 3,146 losses on the enemy.

Surrender of Japan
  
On 13 August, the 1st Cavalry Division was alerted that they were selected to accompany General Douglas MacArthur to Tokyo and would be part of the 8th Army in the occupation of Japan. On 02 September, the long convey of ships steered into Yokohama Harbor and past the battleship Missouri where General MacArthur would later receive the Japanese surrender party. At noon on 05 September 1945, a reconnaissance party headed by Colonel Charles A. Sheldon, the Chief of Staff of the 1st Cavalry Division, entered Tokyo. This embarkment was the first official movement of American personnel into the capital of the mighty Japanese Empire.

At 8:00 on 08 September, a history making convey left Hara-Machida with Tokyo as their destination. Headed by Major General William C. Chase, commanding general of the 1st Cavalry Division, the party included a veteran from each troop of the division. Passing through Hachioji, Fuchu and Chofu, the Cavalry halted briefly at the Tokyo City Limits. General Chase stepped across the line thereby putting the American Occupational Army officially in Tokyo and adding another "First" to its name;

"First in Tokyo".

7th Cavalry Headquarters - Tokyo
  
The first mission of the division was to assume control of the city. On 16 September, the 1st Cavalry Division was given responsibility for occupying the entire city of Tokyo and the adjacent parts of Tokyo and Saitama Prefectures. The command posts of the 1st Brigade, 5th Cavalry and 12th Cavalry were situated at Camp McGill at Otawa, approximately 20 miles south of Yokohama. The 2nd Cavalry Brigade had its command post at the Imperial Guard Headquarters Buildings in Tokyo, while the 7th Cavalry was situated at the Merchant Marine School. The 8th Cavalry occupied the 3rd Imperial Guard Regiment Barracks in Tokyo, which provided greater proximity to security missions at the American and Russian Embassies and the Imperial Palace grounds. Division Headquarters and other units were stationed at Camp Drake near Tokyo.

Troops of the 7th Cavalry Regiment were assigned to guard the American Embassy where General MacArthur had taken up residence. Over the next five years, until the outbreak of the Korean War, the regiment was able to perform many valuable duties and services that helped Japan reconstruct and create a strong, viable economy. On 25 March 1949, the reorganization which began in 1945, was completed by redesignating troops as companies.
