During the next two decades, Thomas chased bandits in Haiti, guarded the U.S. mails, protected American interests in China, and served as naval observer in Egypt when Rommel knocked at the gates of Alexandria in 1941. As operations officer and later chief of staff of the 1st Marine Division, he participated in the Guadalcanal campaign in 1942. The next year he became chief of staff of I Marine Amphibious Corps in the Bougainville operation. Returning to Marine Headquarters in 1944 as Director of Plans and Policies, he was named commanding general of the Marines in China three years later. General Smith had won an enduring place in the hearts of all Marines for his magnificent leadership as well as resourceful generalship during the Inchon-Seoul and Chosin Reservoir campaigns. Speaking of the Marines of April 1951, he paid them this tribute in retrospect: The unit commanders and staff of the Division deserve great credit for the manner in which they planned and conducted the operations which resulted in blunting the Chinese counteroffensive in our area. In my opinion, it was the most professional job performed by the Division while it was under my command.[185] [185] Gen O. P. Smith USMC (Ret.), ltr of 11 Feb 58. The night of 25–26 April passed in comparative quiet for the Marines. A few CCF probing attacks and occasional mortar rounds were the extent of the enemy’s activity. All Marine units had now reached the modified Line KANSAS, but General Van Fleet desired further withdrawals because the enemy had cut a lateral road. IX Corps also directed that the 1st Marine Division be prepared on the 26th to move back to Chunchon, where it would defend along the south bank of the Soyang until service units could move out their large supply dumps. The Division was to tie in on the right with the lower extension of the Hwachon Reservoir, and contact was made in that quarter with the French battalion of the 2d Infantry Division, X Corps. On the Marine left flank the 5th Cavalry of the 1st Cavalry Division had relieved elements of the British Commonwealth Division. Marine regimental officers met with Colonel Bowser, G-3, to plan the continued withdrawal. It was decided that four infantry battalions--1/1, 2/1, 3/5, and 3/7--were to take positions on the west bank of the Pukhan to protect the Mojin bridge and ferry sites while the other units crossed. The execution of the plan went smoothly, without enemy interference. After all other Marine troops were on the east side, 3/7 disengaged last of all and forded the chest-deep stream as a prelude to hiking to Chunchon.[186] [186] 1stMarDiv _HD_, Apr 51; CO 7thMar msg to CG 1stMarDiv, 2040 27 Apr 51.
