In the meantime the Indians had retreated to the lava beds and bade defiance to the soldiers. General Wheaton, commanding the district of the Lakes, ordered the concentration of troops from Camps Warner and Bidwell, while General Canby sent the forces under Colonel John Green and Major Mason from Ft. Vancouver to join the command under General Wheaton. As soon as the settlers could fort up for mutual protection, the entire forces of regulars and volunteers were concentrated at Van Bremer's ranch west of the lava beds under General Wheaton and at Land's ranch on the east side of Tule Lake and directly north of the stronghold. Such was the disposition of the forces when I arrived at headquarters at Van Bremer's ranch. By orders of Governor Grover of Oregon the volunteers under Captains O. C. Applegate and Kelley were placed under the command of General Wheaton. The two companies numbered about 225 men, and were commanded by General John E. Ross, a veteran Indian fighter, but too old to withstand the hardships of a winter campaign against Indians. The men were all poorly provided with clothing and bedding, most all having taken only what they could strap behind their saddles, but in spite of this and a temperature often below zero, no murmur was heard, and all anxiously, eagerly looked forward to a meeting with the brutal savage murderers of their fellow citizens. Such were the conditions when I arrived at headquarters. <sep>The area to where the Indians had retreated, where in proximity to Van Bremer's ranch?<sep>Yes, because the lava beds stronghold was east of Van Bremer's ranch

The Glory of Melaka: In the early days, if you were not a pirate or a mosquito, Melaka was not much of a place to live. The land was infertile, just a swampy plain, the river small and sluggish. But it had a sheltered harbor, protected from the monsoons by neighboring Sumatra. Later, the strategic location and deep-water channel close to the coast brought in the bigger vessels of the trade-wind traffic crossing the Indian Ocean. The first to realize the larger commercial potential, as so often throughout the country's subsequent history, were the Chinese. In 1409, under a new directive from Emperor Chu Ti to pursue trade in the South Seas and the Indian Ocean, a Chinese fleet of 50 ships headed by Admiral Cheng Ho called in at Melaka. They made Parameswara an offer he could not refuse: port facilities and an annual financial tribute in exchange for Chinese protection against the marauding Thais. In 1411, Parameswara took the money to Beijing himself, and the emperor gratefully made him a vassal king. Twenty years later, the Chinese withdrew again from the South Seas trade. The new ruler of Melaka, Sri Maharajah, switched his allegiance to the Muslim trading fraternity by marrying into the Muslim faith, wedding the daughter of a sultan in Sumatra. Islam won its place in Malaya not by conquestas had been the case in North Africa and Europebut by trade, dynastic alliances, and peaceful preaching. Bengali peddlers had already brought the faith to the east coast. In Melaka and throughout the peninsula, Islam thrived as a strong, male-dominated religion of individuality, offering dynamic leadership and preaching brotherhood and self-relianceall qualities ideally suited to the coastal trade. At the same time, Sufi mystics synthesized Islamic teaching with local Malay traditions of animistic magic and charisma, though Islam did not become the state religion until Muzaffar Shah became sultan of Melaka (14461459). But the key figure in the sultanate was Tun Perak, bendahara (prime minister) and military commander. He expanded Melaka's power along the west coast and down to Singapore and the neighboring Bintan islands. He also had orang laut pirates patrolling the seas to extort tribute from passing ships. After Ailied district chiefs had repelled assaults from Thai-controlled armies from Pahang, Tun Perak personally led a famous victory over a Thai fleet off Batu Pahat in 1456. <sep>Who was the first to exploit the commercial potential of the region and who was the admiral who took charge?<sep>The Chinese; Chengo Ho

(CNN) -- Women seeking an abortion in Texas will have to view a picture of the embryo or fetus and hear a description of its development before having the procedure, under a law that takes effect September 1. The bill stirred some controversy in Texas, but it easily passed through the state House and Senate, both of which are controlled by Republicans. It was signed into law Thursday by Republican Gov. Rick Perry. The law says that at least 24 hours before an abortion is performed, women must undergo a sonogram, a procedure that uses ultrasound to create an image. The doctor, then, is required to give, "in a manner understandable to a layperson, a verbal explanation of the results of the sonogram images, including a medical description of the dimensions of the embryo or fetus, the presence of cardiac activity, and the presence of external members and internal organs," the law states. There are some exceptions, including pregnancies that resulted from sexual assault, incest or other violations of law. Women seeking abortions also are exempt if the fetus has been found to have an irreversible medical condition that will cause a disability. "Governor Perry was pleased to sign this important legislation, which bolsters our efforts to protect life by ensuring Texans are fully informed when considering such an important decision," said his deputy press secretary, Lucy Nashed. Critics say the new law is unnecessary. "What no one is focusing on is that this is a mandate to humiliate women who want an abortion," said Yvonne Gutierrez, vice president for public affairs at the Planned Parenthood Trust of South Texas. Texas already requires a 24-hour consent period, and the new law will simply add emotional and financial costs to those seeking abortions, she said. <sep>Who signed this bill, which stirred some controversy in Texas, into law on Thursday?<sep>Senate signed it into law
