Papuan campaign

Brigadier Generals Hanford MacNider, Albert W. Waldron, and Clovis E. Byers recuperate in hospital in Australia after being wounded in the Battle of Buna-Gona.

When the Battle of Buna-Gona started going badly, General Douglas MacArthur, the Supreme Commander, South West Pacific Area, decided to send I Corps headquarters to the front in Papua. Eichelberger recalled Macarthur's instructions:

"Bob," he said, "I want you to go out there and take Buna, or don't come back alive." He paused for a moment and then, without looking at Byers, pointed a finger. "And that goes for your chief of staff, too."^[5]

In accordance with MacArthur's orders, Eichelberger relieved the 32nd Infantry Division's commander, Major General Edwin F. Harding, replacing him with the division's artillery commander, Brigadier General Albert W. Waldron, on December 2, 1942.^[6] In an attack on December 5, Waldron was shot in the shoulder by a Japanese sniper,^[7] and Byers succeeded him as commander of the troops in the field.^[8] Byers in turn was wounded on December 16. He became the third American general to be shot at Buna, Brigadier General Hanford MacNider having been shot earlier in the fighting, none of whom was more than 75 metres from Japanese lines at the time.^[9] General Eichelberger assumed command, as he was now the only American general officer present. Waldron and Byers were awarded the Distinguished Service Cross.^[10] Byers' citation read:

For extraordinary heroism in action near Buna, New Guinea, on 15 December 1942. Immediately prior to launching an attack on an enemy position, Brigadier General Byers, without regard to his personal safety, visited the front line troops in close proximity to the enemy and to the impact are of our own preparatory mortar concentration, inspiring the men to a greater effort by his personal example. When the attack was launched, he advanced to a position within fifty yards of the assaulting troops. When wounded by an enemy sniper, he continued observation of the action and encouragement of the troops until he was evacuated. His inspiring example of heroism contributed greatly to the success of the attack.^[11]

For his role in the fighting in Papua, Byers also received the Silver Star and Purple Heart. In turn, Byers recommended Eichelberger for the Medal of Honor but the nomination was disapproved by MacArthur.^[12] Byers returned to the front on January 17, 1943, as Chief of Staff of Advance New Guinea Force, now commanded by Eichelberger. The two remained until January 26, when they returned to Australia.^[1]

As Chief of Staff, General Byers performed outstanding and meritorious services in coordinating the several planning units during the preparation for an amphibious operation. During the combat phase of this operation his unremitting tact and energy were responsible for the prompt installation and subsequent forward displacement of the task force headquarters with a minimum of confusion and delay. His outstanding example during the long hours of work under trying circumstances served as an inspiration to all those whom he came in contact.^[13]

Byers was awarded an Oak Leaf Cluster to his Silver Star in the Battle of Biak. His citation read:

For gallantry in action on Biak, Netherlands East Indies, on 17 June 1944. Troops of the HURRICANE Task Force, dispirited by three weeks of vicious fighting, were in a critical condition in the Sump area on Biak Island. The Japanese, hidden in caves, had maintained their principal lines of resistance despite all efforts of American forces. At this point General Byers made a personal reconnaissance of the most advanced positions. Although enemy mortar shells were bursting behind him, he continued to observe the enemy and to obtain information which was instrumental in the subsequent defeat of Japanese forces. The disheartened American troops were inspired by General Byers' conspicuous bravery and his disregard of danger instilled with them the spirit vital to victory. The spectacular leadership exhibited by General Byers in this action is within the highest tradition of the military service.^[14]

He was also awarded an Oak Leaf Cluster to his Bronze Star Medal. This citation read:

On one such occasion a motor vehicle following closely behind that in which he rode was ambushed by the enemy and all the occupants were killed. In addition, he made an aerial reconnaissance of a suspected enemy point of resistance based on fortified caves. The information thus obtained was of great value in eliminating the position.^[15]

Lieutenant General Walter Krueger, commander of the Sixth Army offered to make Byers an assistant division commander. When Byers refused the offer, Krueger took this as a personal affront.^[16]
