Five Spahis were killed. British Air Marshal Arthur Barratt, impatient with the reluctance of the French Air Force to conduct air strikes, ordered a flight of Fairey Battle bombers from the 226 Squadron to attack German tank columns. They went unescorted and encountered heavy anti-aircraft fire. Most were damaged by flak but managed to escape. One received a direct hit and crashed near Bettendorf. German soldiers pulled the three injured crew from the burning wreckage, one of whom later died in a local hospital. The Grand Ducal Gendarmerie resisted the German troops, but to little avail; the capital city was occupied before noon. The Gendarmerie chain of command in the south was thrown into disarray by the influx of refugees and the arrival of German and French troops. Most gendarmes escorted refugees over the border, while some abandoned their posts and fled to France. Total Luxembourgish casualties amounted to six gendarmes and one soldier wounded, while 22 soldiers (six officers and 16 non-commissioned officers) and 54 gendarmes were captured. By the evening of 10 May 1940, most of the country, with the exception of the south, was occupied by German forces. More than 90,000 civilians fled from the canton of Esch-sur-Alzette as a consequence of the advance. 47,000 evacuated to France, 45,000 poured into the central and northern part of Luxembourg. On 11 May the Grand Ducal government reached Paris and installed itself in the Luxembourg legation. Fearing German aerial attack and finding the small facilities unsuitable, the government moved further south, first to Fontainebleau, and then Poitiers. It later moved to Portugal and the United Kingdom, before finally settling in Canada for the duration of the war. Charlotte, exiled in London, became an important symbol of national unity. Her eldest son and heir, Jean, volunteered for the British Army in 1942. The only official representative left behind was , head of the Ministry of State Affairs, as well as the 41 deputies. By the end of May Wehrer and several high ranking functionaries established a provisional "Administrative Commission" to govern Luxembourg in lieu of the Grand Ducal family and the other ministers. Wehrer retained the Ministry of State Affairs and assumed responsibility for Foreign Relations and Justice; Jean Metzdorf held the portfolios for Interior, Transportation, and Public Works; Joseph Carmes managed Finance, Labour, and Public Health; Louis Simmer oversaw Education, and Mathias Pütz directed Agriculture, Viticulture, Commerce, and Industry.
