1919 Motor Transport Corps convoy
The 1919 Motor Transport Corps convoy was a long distance convoy carried out by the US Army Motor Transport Corps that drove over on the historic Lincoln Highway from Washington, D.C., to Oakland, California and then by ferry over to end in San Francisco.
Lt. Col. Charles W. McClure and Capt. Bernard H. McMahon were the respective expedition and train commanders and civilian Henry C. Ostermann of the Lincoln Highway Association was the pilot. Official observers included those from the Air Service, A.S.A.P., Coast and Field Artillery, Medical Corps, Ordnance, Signal Corps and Tank Corps including the then Brevet Lieutenant Colonel Dwight D. Eisenhower. Eisenhower later said he joined the convoy partly for a lark, and partly to learn.
Organization
The Signal Corps filmed convoy events; and the civilians of the Goodyear band were transported from Chicago in one of the trucks. The Publicity Officer rode with Ostermann 2–10 days ahead of the main body, while the Recruiting Officer was 1–2 days ahead, and the Cook and Mess units were several hours ahead, Two motorcycles scouted about hour ahead to report conditions and place markers. The 5th Engineers' Company E of 2 officers and 20 men headed the main body with the in the lead followed by the machine shop and blacksmith shop trucks, and the Quartermaster Corps' Service Park Unit 595 of 1 officer and 43 men brought up the rear. In addition to 230 road incidents resulting in 9 vehicles retiring, the convoy of "24 expeditionary officers, 15 War Department staff observation officers, and 258 enlisted men" had 21 injured en route who did not complete the trip. Although some "were really competent drivers" by the end, the majority of soldiers were "raw recruits with little or no military training"; and except for the Motor Supply Company E commander, troop officers had "meager knowledge" of "handling men in the field".Equipment
In addition to engineer and quartermaster units; the convoy had 2 truck companies of the 433rd Motor Supply Train; a medical unit with surgeon, medical, and dental officers; and a Field Artillery Detachment which provided the Maxwell crawler tractor operated by a civilian. The 81 total vehicles and trailers included "34 heavy cargo trucks, 4 light delivery trucks", 2 mobile machine shops, 1 blacksmith shop, and 1 wrecking truck, actually a Millitor "Artillery Wheeled Tractor" that once towed 9 trucks at once and was equipped with a power winch. There were "2 spare parts stores, 2 water tanks, 1 gasoline tank, 1 searchlight with electrical power plant truck, 4 kitchen trailers, 8 touring cars, 1 reconnaissance car, 2 staff observation cars, 5 sidecar motorcycles, and 4 solo motorcycles"; as well as five GMC ambulances with two ambulance trailers, . Additional vehicle manufacturers included Cadillac, Dodge, F.W.D., Garford, Harley-Davidson & Indian, Liberty, Mack, Packard, Riker, Standardized, Trailmobile, and White. The heavy trucks included three examples of each of three wartime commercial models in the 3 to 5-1/2 ton range being considered for continued service along with eleven 1-1/2 ton trucks from Garford, GMC, Packard and White. The four "light delivery trucks" were 3/4 ton Dodges and the remainder were 3 ton Class B Standardized Military "Liberty" trucks.Dealers en route supplied gasoline and tires to the convoy and the Firestone Tire and Rubber Company provided 2 trucks fitted with "giant cord pneumatic" tires that carried spare standard tires. One Firestone truck detoured to Reno, Nevada, to have a new giant tire mounted. Six vehicles were chosen to evaluate Dixon's Graphite Grease to see if it provided worthwhile benefits.
Operations
In the course of its journey, the convoy broke and repaired dozens of wooden bridges and "practically" all roadways were unpaved from Illinois through Nevada. Dust was a constant problem. The convoy travelled up to, and the schedule was for to average. The actual average for the covered in 573.5 hours was over the 56 travel days for an average of 10.24 hours per travel day. Six rest days without convoy travel were at East Palestine, Ohio; Chicago Heights, Illinois; Denison, Iowa; North Platte, Nebraska; Laramie, Wyoming; and Carson City, Nevada. The shortest driving periods between control points were from Council Bluffs, Iowa, to Omaha, Nebraska and Delphos, Ohio, to Fort Wayne, Indiana, while 4 days had average speeds over : E Palestine OH to Wooster OH, South Bend IN to Chicago Heights Il, Jefferson IA to Denison IA, and Anderson's Ranch NV to Ely NV.At many stops along the way the convoy was escorted into town by local dignitaries and feted with church bells, parades, concerts, picnics, dances and banquets. For example, the log entry for July 18 reads "At 8:00 A. M. halted by request in Churubusco, Ind for 10 min., while refreshments were served by local Red Cross Canteen Service. Met and escorted through South Bend by Major F.R. Carson, Chief of Policy Peter Kline, Fire Chief I.A. Sorbell, Secretary Chamber of Commerce Jos. F. Kelley, Reception Comm. of prominent citizens, 3 Fire Companies and two bands, furnished by the Chamber of Commerce and the Goodrich Company." One pedestrian was struck, non-fatally, in Valparaiso, Indiana. In western Wyoming Eisenhower and a companion convinced the convoy that an Indian attack was imminent. Sentinels were posted that night, but when Ike and friend exchanged warrior yelps outside the perimeter a young officer on guard discharged his weapon. They had to stop a telegram being sent to the War Office reporting an encounter with hostile Indians.
Delays
Convoy delays required extra encampments at Sewickley, Pennsylvania ; Gothenburg, Nebraska ; and Ogallala, Nebraska ; which delayed arrival at Evanston, Wyoming, to August 16 instead of the scheduled August 13. To the next control point, the convoy travelled instead of the planned 88 and used extra camps at Echo, Utah, and Ogden, Utah ; arriving at Salt Lake City on the 19th. Despite travelling on the August 24 rest day, the convoy fell behind an additional day using 4 travel days instead of the 2 scheduled travel days from Orr's Ranch, Utah, through the Great Salt Lake Desert to Ely, Nevada; where the convoy arrived on the 24th. An extra travel day on "mining roads" was used between Ely and Austin, Nevada; where the convoy arrived on the 27th, short of the scheduled point for the 27th. The convoy remained 7 days behind schedule through Oakland, California, where it arrived September 5 at 4 pm. Forgoing a rest day originally scheduled for the day after arriving in Oakland, the convoy instead ferried to San Francisco the next morning 6 days behind schedule and parked at the Presidio of San Francisco.Results
In addition to transporting New York's Medal of Joan of Arc for San Francisco's Palace of Fine Arts, the convoy had four objectives; and Ordnance Department and Tank Corps observers completed their reports in October.The objectives were:
- Encourage "construction of through-route and transcontinental highways". The Ordnance Department notes "great interest in the Good Roads Movement was aroused by the passage of the Convoy".
- Procure "recruits for... the Motor Transport Corps": enlistment through the convoy was sparse
- Exhibit "to the public... the motor vehicle for military purposes": In the course of the journey, the convoy "passed through 350 communities, and it was estimated that more than 3,000,000 people witnessed it along the route."
- Study & observe "the terrain and standard army vehicles":. The Tank Corps Observer noted that "the light truck is so far superior to the heavy should be confined to... hard surfaced roads; and... short hauls."
Lt. Jackson, the Ordnance Department Observer, submitted a detailed report on the performance of all of the convoy's vehicles. The Cadillac and Dodge passenger cars and light trucks were found to be generally satisfactory, though the hood latches on the Dodge proved insufficiently durable. Of the transport trucks, the FWD proved the most satisfactory and the Garford the least, the former due to its mechanical reliability and all wheel drive and the latter due to a fragile cooling system, though the Standard B "Liberty" trucks were actually the most towed trucks in the convoy. The White, GMC, Riker, Packard and Mack trucks also proved satisfactory, though the latter's chain drive rendered them unsuitable for poor roads, and the larger motorcycles would have benefitted from more robust tires. Most of the failures that were not caused by operator error were due to the effects of the constant dust, vibration and pounding on the carburetors, ignition systems, bushings, fasteners and bearings. The various trailers were also evaluated and the graphite grease was determined to provide significant benefits. Finally, the Maxwell and Militor tractors were praised for their overall reliability and mechanical superiority, as the trip could not have been completed without them. Lt. Jackson also noted "The maintenance work was considerably hampered by the necessity of carrying spare parts for so many different makes of trucks" and "better tools should be furnished to the mechanics".
