Question: When was the company responsible for delivering messages, newspapers, and mail in the Butterfield Overland Mail route?

<P0-S0> The Butterfield Overland Mail was a transport and mail delivery system that employed stagecoaches that traveled on a specific route between Saint Louis, Missouri and San Francisco, California and which passed through the New Mexico Territory. <P0-S1>  It was created by the United States Congress on March 3, 1857, and operated until March 30, 1861. <P0-S2>  The route that was operated extended from where the ferry across the Colorado River to Fort Yuma Station, California was located, through New Mexico Territory via, Tucson to the Rio Grande and Mesilla, New Mexico then south to Franklin, Texas, midpoint on the route. <P0-S3>  The New Mexico Territory mail route was divided into two divisions each under a superintendent. <P0-S4>  Tucson was the headquarters of the 3rd Division of the Butterfield Overland Mail Company. <P0-S5>  Franklin Station in the town of Franklin, (now El Paso, Texas), was headquarters of the 4th Division. <SEP> <P1-S0>  West of "Soldiers Farewell Hill" on the west bank of a drainage arroyo, the stop was on the Butterfield Overland Mail route (1858-1861) in Grant County, New Mexico. <P1-S1> 'Soldiers Farewell Stage Station was a stagecoach stop of the 1858-1861 Butterfield Overland Mail route before the company moved to the central route (former Pony Express route). <P1-S2>  According to the Overland Mail Company Through Time Schedule, it was 150 miles (33½ hours) west of El Paso, Texas and 184½ miles (41 hours) east of Tucson, Arizona. <P1-S3>  Located 42 miles east of Stein's Peak Station and 14 miles southwest of Ojo de Vaca Station. <SEP> <P2-S0> In Texas, the Butterfield Overland Mail service created by Congress on March 3, 1857, operated until March 30, 1861. <P2-S1>  The route that was operated extended from San Francisco, California to Los Angeles, then across the Colorado Desert to Fort Yuma, then across New Mexico Territory via, Tucson and Mesilla, New Mexico to Franklin, Texas, midpoint on the route. <P2-S2>  The route through Texas followed first the northern route to the Pecos River and downstream to Horse Head Crossing. <P2-S3>  The route in West Texas was changed in 1859, in order to secure a better water supply on the route and to provide mail service to a more settled area, the stages between Franklin and the Pecos River followed the San Antonio-El Paso Road to Camp Stockton and then turned east to Horsehead Crossing. <P2-S4>  From Horsehead Crossing the route crossed Texas to the Red River and into Indian Territory. <P2-S5>  In 1860 the route was changed to another route from Jacksboro to Sherman via Decatur due to the building of a new toll bridge at Bridgeport, that avoided delays crossing the West Fork of the Trinity River when it was flooded. <P2-S6>  From Colberts Ferry the route went on to Fort Smith, then up across Arkansas and southwest Missouri to Tipton with the final leg by train to St. Louis. <P2-S7>  The Texas mail route was so long that the route there, like that in California, was divided into two divisions each under a superintendent. <SEP> <P3-S0> The Pony Express was a mail service delivering messages, newspapers, and mail.
