Special units, such as KGr 100, became the Beleuchtergruppe (Firelighter Group), which used incendiaries and high explosive to mark the target area. The tactic was expanded into Feuerleitung (Blaze Control) with the creation of Brandbombenfelder (Incendiary Fields) to mark targets. These were marked out by parachute flares. Then bombers carrying SC 1000 (1,000 kg (2,205 lb)), SC 1400 (1,400 kg (3,086 lb)), and SC 1800 (1,800 kg (3,968 lb)) "Satan" bombs were used to level streets and residential areas. By December, the SC 2500 (2,500 kg (5,512 lb)) "Max" bomb was used.

Unhappy with this change of policy by the Portuguese government, Napoleon sent an army to invade Portugal. On 17 October 1807, 24,000 French troops under General Junot crossed the Pyrenees with Spanish cooperation and headed towards Portugal to enforce Napoleon's orders. This attack was the first step in what would eventually become the Peninsular War, a six-year struggle that significantly sapped French strength. Throughout the winter of 1808, French agents became increasingly involved in Spanish internal affairs, attempting to incite discord between members of the Spanish royal family. On 16 February 1808, secret French machinations finally materialized when Napoleon announced that he would intervene to mediate between the rival political factions in the country. Marshal Murat led 120,000 troops into Spain and the French arrived in Madrid on 24 March, where wild riots against the occupation erupted just a few weeks later. Napoleon appointed his brother, Joseph Bonaparte, as the new King of Spain in the summer of 1808. The appointment enraged a heavily religious and conservative Spanish population. Resistance to French aggression soon spread throughout the country. The shocking French defeat at the Battle of Bailen in July gave hope to Napoleon's enemies and partly persuaded the French emperor to intervene in person.
How many troops did Napoleon send to begin the invasion of Portugal?
A: 24,000

Practitioners of such sports reveal that, because of the city's dry weather, the city offers strong thermal winds and great "cloud-streets", which is also the name for a manoeuvre quite appreciated by practitioners. In 2003, Brasilia hosted the 14th Hang Gliding World Championship, one of the categories of free flying. In August 2005, the city hosted the 2nd stage of the Brazilian Hang Gliding Championship.
