The truck companies of the 8th Transportation Group delivered cargo along the most heavily ambushed road in Vietnam, QL19, through the Central Highlands in northern II Corps Tactical Zone. The 523rd had five 5-ton gun trucks at the time. The Group Commander considered the 523rd his best truck company and when instructed to send two light truck companies north to I Corps Tactical Zone for the upcoming Laotian Incursion, Operation Lam Son 719, in February through April 1971, he chose to send his best. The 523rd was attached to the 39th Transportation Battalion and stationed at the abandoned Marine Corps base Camp Vandergrift. During the two-and-a-half-month incursion into Laos, the North Vietnamese Army tried to close down the supply route with 23 convoy ambushes. Baird fought in two of the operation's deadliest ambushes and lost his left arm during the convoy ambush on March 12, 1971. He earned a Bronze Star and two Purple Hearts. In 2012, the 523rd Transportation Company was inducted into the Transportation Corps Hall of Fame for its heroism during Operation Lam Son 719.
