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: What day did the expedition end that Vizcarra led against the Navajo of western New Mexico?

The Polovtsy raid of 1068-1069 was only the tribe's second major raid into Rus'  in 1055, but the tribesmen broke the treaty and attacked Kievan Rus' six years later, defeating Vsevolod in battle).  In 1068-1069, the Polovtsy penetrated the earthwork defensive lines built up over the years by Prince Vladimir Svyatoslavich  and his son, Yaroslav the Wise .  They were met by a combined army of Yaroslav's sons: Grand Prince Iziaslav of Kiev and his brothers, Princes Sviatoslav Yaroslavich of Chernigov, and Vsevolod, which was defeated and fled back to Kiev in disarray. The Polovsty continued to raid throughout the area, prompting the Kievans to call on the grand prince to rearm them so they could march out and meet the threat.  Iziaslav refused, prompting the rebellion.  The Tale of Bygone Years , a part of The Lavrentian Chronicle, relates what happened next:

Passage: The first German battlecruiser——was commenced March 1908. Four Parsons turbines were used, improving speed to 27 knots and reducing weight. Four twin turrets mounted 28 cm guns; although the two centre turrets were still placed one either side of the ship, they were offset so could now fire either side. The design was considered a success, but the cost at 35.5 million marks was significantly above the 1906 allocation. Light cruiser development continued with the  light cruisers, which were to become famous for their actions in the start of World War I in the Pacific. The ships were 3,300 tons, and armed with ten 10.5 cm rapid fire guns and a speed around 24 knots.  cost 7.5 million marks, and  6 million marks. Four  were produced between 1907 and 1911 at 4,400 tons and around 8 million marks each. These had turbines, twelve 10.5 cm guns as main armament, but were also equipped to carry and lay 100 mines. From 1907 onward, all torpedo boats were constructed using turbine engines.
Question: How many years after funds were allocated to build the first German battlecruiser  did building commence?
