who was sent to the rio grande to claim the southern border of texas
History of Texas (1845–1860) When Texas was annexed, Mexico broke diplomatic relations with the United States. The annexation bill did not specifically define the boundaries of Texas. The former republic claimed the Rio Grande as its southern border, while Mexican authorities had always considered the Nueces River, situated further north, to be the boundary of Mexican Texas. The United States sent John Slidell to negotiate with the Mexican government, offering l $25 million ($692,019,231 today) to set the Texas border at the Rio Grande and to purchase Mexico's provinces of Alta California and Santa Fe de Nuevo México. Popular sentiment in Mexico was against any sale, and the army deposed President José Joaquín de Herrera when he appeared inclined to negotiate with Slidell.

Ulysses S. Grant and the American Civil War In January 1863, McClernand and Sherman's combined XIII and XV corps, the Army of the Mississippi, defeated the Confederates at Arkansas Post. Grant made five attempts to capture Vicksburg by water routes; however, all failed. With the Union impatient for a victory, in March 1863, the second stage to capture Vicksburg began. Grant marched his troops down the west side of the Mississippi River and crossed over at Bruinsburg. Adm. David D. Porter’s navy ships had previously made a run past Vicksburg's batteries on April 16, 1863, enabling Union troops to be transported to the east side of the river. The crossing succeeded due to Grant's elaborate series of demonstrations and diversions that masked his intended movements from the Confederates. After the crossing, Grant maneuvered his army inland, and after a series of battles, the state capital, Jackson, Mississippi, was captured. Confederate general John C. Pemberton was defeated by Grant’s forces at the battles of Champion Hill and of Black River Bridge and retreated to the Vicksburg fortress. After two unsuccessful and costly assaults on Vicksburg, Grant settled in for a 40-day siege. Pemberton, unable to combine forces with the army of Joseph E. Johnson, which was hovering in central Mississippi, finally surrendered Vicksburg on July 4, 1863.[16] The capture of Vicksburg was a turning point for the Union war effort. The surrender of Vicksburg and the defeat of Confederate general Robert E. Lee at Gettysburg were stinging defeats for the Confederacy, now split in two by the Union's domination of the Mississippi River. President Lincoln promoted Grant to the permanent rank of Major General in the Regular Army. Vicksburg marked the second surrender of a Confederate army (the other being Buckner's surrender to Grant the year before). During the Vicksburg siege, Grant dismissed McClernand for publishing to the press a congratulatory order that seemed to claim it was McClernand's corps that was winning the campaign. McClernand appealed the dismissal to his personal friend, President Lincoln, but to no avail. Grant had ended the rivalry on his own terms. The Union army had captured considerable Confederate artillery, small arms, and ammunition. Total casualties, killed or wounded, for the final operation against Vicksburg that started on March 29, 1863 were 10,142 for the Union and 9,091 for the Confederacy.[16]
Battle of San Jacinto Santa Anna, the President of Mexico, was captured the following day and held as a prisoner of war. Three weeks later, he signed the peace treaty that dictated that the Mexican army leave the region, paving the way for the Republic of Texas to become an independent country. These treaties did not specifically recognize Texas as a sovereign nation, but stipulated that Santa Anna was to lobby for such recognition in Mexico City. Sam Houston became a national celebrity, and the Texans' rallying cries from events of the war, "Remember the Alamo!" and "Remember Goliad!," became etched into Texan history and legend.
