Passage: Melgares's successor, Governor José Antonio Vizcarra met Navajo leaders at Paguate on 12 February 1823. His terms essentially stated that the Spanish would settle the Navajo in pueblos and energetically convert them to the Catholic religion. The Navajo were not interested in either of these proposals. They rejected the treaty and renewed the fight. Six New Mexicans were killed at Socorro in April and eight more at Sabinal in May. On 18 June 1823, Vizcarra led 1,500 troops in a 74-day expedition against the Navajo of western New Mexico. His route took him through the Chuska Mountains to the Hopi mesas in what is now Arizona, then north towards Utah, reaching Oljeto Creek in what is now San Juan County, Utah. Thirty-three Navajo were killed, of whom eight were women, and about 30 were captured. The expedition reached Canyon de Chelly in what is now eastern Arizona. In retaliation for Vizcarra's expedition, the Navajo raided Socorro again, and attacked Tome, Albuquerque and reached the outskirts of Santa Fe. The 1823 raid marked the start of a long period of raids and counter raids lasting until 1848 as New Mexicans took Navajo captive to work as slaves, and as Navajo raided to recover their people and to obtain livestock. 
Question: How many month after Governor Jose Antonio Vizcarra met Navajo leaders at Paguate did he lead 1500 troops on an expedition against the Navajo of western New Mexico?

Passage: In May 1944, as the war began to turn in favor of the Allies, WCBW reopened the studios and the newscasts returned, briefly anchored by Ned Calmer, and then by Everett Holles. After the war, expanded news programs appeared on the WCBW schedule - whose call letters were changed to WCBS-TV in 1946 - first anchored by Milo Boulton, and later by Douglas Edwards. On May 3, 1948, Edwards began anchoring CBS Television News, a regular 15-minute nightly newscast on the CBS television network, including WCBS-TV. It aired every weeknight at 7:30 p.m., and was the first regularly scheduled, network television news program featuring an anchor . NBC's offering at the time, NBC Television Newsreel , was simply film footage with voice narration. In 1950, the name of the nightly newscast was changed to Douglas Edwards with the News, and the following year, it became the first news program to be broadcast on both coasts, thanks to a new coaxial cable connection, prompting Edwards to use the greeting "Good evening everyone, coast to coast." The broadcast was renamed the CBS Evening News when Walter Cronkite replaced Edwards in 1962. Edwards remained with CBS News with various daytime television newscasts and radio news broadcasts until his retirement on April 1, 1988. 
Question: How many years did Edwards remain with CBS News before he retired in 1988?

Passage: Although the Curonians had attacked Riga in 1201 and 1210, Albert of Buxhoeveden, considering Courland a tributary of Valdemar II of Denmark, had been reluctant to conduct a large scale campaign against them. After Albert's death in 1229, the crusaders secured the peaceful submission of Vanemane  by treaty in 1230. In the same year the papal vice-legat Baldouin of Alnea annulled this agreement and concluded an agreement with the ruler of Bandava in the central Courland Lamekins , delivering his kingdom into the hands of the papacy. Baldouin became the popes's delegate in Courland and bishop of Semigallia; however, the Germans complained about him to the Roman Curia, and in 1234 Pope Gregory IX removed Baldouin as his delegate. After their decisive defeat in the Battle of Saule by the Samogitians and Semigallians, the remnants of the Swordbrothers were reorganized in 1237 as a subdivision of the Teutonic Order, and became known as the Livonian Order. In 1242, under the leadership of the master of the Livonian Order Andrew of Groningen, the crusaders began the military conquest of Courland. They defeated the Curonians as far south as Embūte, near the contemporary border with Lithuania, and founded their main fortress at Kuldīga. In 1245 Pope Innocent IV allotted two thirds of conquered Courland to the Livonian Order, and one third to the Bishopric of Courland. At the Battle of Durbe in 1260 a force of Samogitians and Curonians overpowered the united forces of the Livonian and Teutonic Orders; over the following years, however, the Crusaders gradually subjugated the Curonians, and in 1267 concluded the peace treaty stipulating the obligations and the rights of their defeated rivals. The unconquered southern parts of their territories  were united under the rule of the Grand Duchy of Lithuania. 
Question: How many years was it from Albert's death to the treaty for the peaceful submission of Vanemane?
