Mules in the CBI and their Veterinarians
We often comment on the animals who help us, especially in war, BUT the Veterinarians who care for them are very rarely given a voice…
I received a message from Lavinia Ross @ Salmon Brook Farms about her veterinarian, D.E. Larsen, DVM and his mentor, Robert W. Davis, DVM, Please visit to read!
“GP, you might like this post by our old veterinarian who retired some years back. One of his mentors in vet school was the same veterinarian who cared for the mules used by Merrill’s Marauders in Burma during WWII.”
The most famous American unit of the CBI was the 5307th Composite Unit, also known as “Merrill’s Marauders.” Undertaking operations similar to those of the Chindits, it used large numbers of mules. Six Quartermaster pack troops were part of the unit, and mules were liberally issued to the rest of the unit as well to transport their own equipment and supplies. Each troop had about 300 mules and 75 men.
During campaigns the mules proved their worth time and again. Don L. Thrapp served with the Marauders and later wrote of his experiences with the pack mules during the fighting at Tonkwa against the Japanese. “They were zeroed in on our bivouac area at a river crossing, and their fire caused us some casualties in men and animals. One tree burst accounted for seven animals. Another shell cut between two mules … and burst about eight feet behind them, but injured neither.”
In the words of a veteran of the China-Burma-India Theater, retired Technical Sergeant Edward Rock Jr., [they] “served without a word of complaint or lack of courage. They transported artillery, ammunition, food, and medicine, and under enemy fire transported the wounded. Many of the CBI veterans are here today because a mule stopped a bullet or a piece of shrapnel meant for the GI. Mules fell in battle, mortally wounded, and we shed tears for them.”
Pack mules indeed performed yeoman service in Asia and other theaters during World War II, hauling weapons and equipment as well as saving lives by carrying wounded off the front lines. They took the same risks as their human masters and too often they paid the ultimate price.
A report on April 4, 1944, from one of the units of Merrill’s Marauders described their sacrifice in detail: Japanese artillery fire had killed or wounded most of the unit’s mules. The mules really proved their value in the CBI with both British and American units fighting there. The famous British Brigadier Orde Wingate used large numbers of mules to supply his Chindit Brigade.
After the war, the mules were not forgotten. A beloved character, “Francis the talking mule.” became a well-known movie. https://pacificparatrooper.wordpress.com/2020/04/20/francis-the-talking-mule/
