The fighting within the town had become extremely intense, becoming a door to door battle of survival. Despite a never-ending attack of Prussian infantry, the soldiers of the 2nd Division kept to their positions. The people of the town of Wissembourg finally surrendered to the Germans. The French troops who did not surrender retreated westward, leaving behind 1,000 dead and wounded and another 1,000 prisoners and all of their remaining ammunition. The final attack by the Prussian troops also cost c.1,000 casualties. The German cavalry then failed to pursue the French and lost touch with them. The attackers had an initial superiority of numbers, a broad deployment which made envelopment highly likely but the effectiveness of French Chassepot rifle-fire inflicted costly repulses on infantry attacks, until the French infantry had been extensively bombarded by the Prussian artillery.

In which direction did the French troops who did not surrender head?
Answer: westward

Child labour played an important role in the Industrial Revolution from its outset, often brought about by economic hardship. The children of the poor were expected to contribute to their family income. In 19th-century Great Britain, one-third of poor families were without a breadwinner, as a result of death or abandonment, obliging many children to work from a young age. In England and Scotland in 1788, two-thirds of the workers in 143 water-powered cotton mills were described as children. A high number of children also worked as prostitutes. The author Charles Dickens worked at the age of 12 in a blacking factory, with his family in debtor's prison.

How many water-powered cotton mills used child labour in 1788 England and Scotland?
Answer:
143
