The first reinforcement to the Teutonic forces arrived in early 1261, but was wiped out on January 21, 1261 by Herkus Monte in the Battle of Pokarwis. In January 1262 reinforcements arrived from the Rhineland, led by Wilhelm VII, Duke of Jülich, who was obliged by Pope Alexander IV to fulfil his crusader duties in Prussia. This army broke the Siege of Königsberg but as soon as the army returned home, the Sambians resumed the siege and were reinforced by Herkus Monte and his Natangians. Herkus was later injured and the Natangians retreated, leaving the Sambians unable to stop supplies reaching the castle and the siege eventually failed. Prussians were more successful capturing castles deeper into the Prussian territory , and the Knights were left only with strongholds in Balga, Elbing, Culm, Thorn, and Königsberg. Most castles fell in 1262-1263, and Bartenstein fell in 1264. The Prussians destroyed captured forts instead of using them for their own defence, so the end of successful sieges meant that large Prussian forces did not have to stay near their home and were then free to operate in other parts of Prussia, raiding the Culmerland and Kuyavia. A recovered Herkus Monte raided Culmerland with a large force and took many prisoners in 1263. On his way back to Natangia, Herkus and his men were confronted by a contingent of their enemies. In the Battle of Löbau that ensued, Prussians killed forty knights, including the Master and the Marshal. The Prussians also received help from Lithuanians and Sudovians. In summer of 1262 Treniota and Shvarn attacked Masovia, killing Duke Siemowit I, and raided Culmerland, provoking Pogesanians to join the uprising. However, assassination of Mindaugas and subsequent dynastic fights prevented Lithuanians from further campaigns. Skalmantas, leader of Sudovians, raided Culm  in 1263 and in 1265.

What battle started second: Battle of Pokarwis or Battle of Löbau?

The screening suggests that in 2000, 19 percent of all newborn babies in Metropolitan France had at least one parent originating from one of the risk regions. The figure for 2007 was 28.45 percent, for 2010 31.5 percent, for 2012 34.44 percent, for 2013 35.7 percent, and for 2015 38.9 percent. These percentages vary widely among French regions; for example, in 2015, screening suggested that only 8.1% of children born in Brittany had a parent originating from a sickle-cell risk region, while 73.4% of children born in Île-de-France (which includes Paris) did. The percentage for Île-de-France was a significant increase from 54.2% in 2005. However, a 2014 story in Le Monde suggested that the testing figures for Île-de-France were distorted by the practices of some hospitals in the region, which choose to test all babies whether or not they have parents with ancestry from an endemic sickle-cell region.

How many percent increase was seen between 2000 and 2015 of at least one parent of babies born in Metropolitan France originating from one of the risk regions?
A:
19.9
