MISSOURI HISTORICALSOCIETY, ST. LOUIS (ABOVE), AND THE BEALECOLLECTION,VAN NUYS, CALIFORNIA Chamberlain, volunteer from Boston, stand as a unique documentary of the war. "Storming the Bishop's Palace" reveals fighting still raging at Monterrey in Mexi co, even as the United States flag replaces the Mexican tri color (left). Government expeditions systematically explored the blank areas of the map. One of the first trained topogra phers to chart the Far West, John C. Fremont became known as the Pathfinder. In the painting at right by Joseph Boggs Beale, Fremont plants the Stars and Stripes in the central Rockies, August 15, 1842. Two years later he crossed the Sierra Nevada in midwinter, a feat that even the Indians said could not be done. In June, 1846, while ostensibly exploring northern California, Fremont helped instigate a successful insur rection against Mexican rule that culminated in the Cali fornia Republic. Four years later, California entered the Union as the 31st state.
