Question: Which of the two countries where Brandenburg units seized several bridges has a larger population? Passage:During the spring 1940 , the Brandenburg units proved essential in seizing "vital points ahead of Guderian's panzers." On May 8, 1940, the men of the 4th company led by Leutnant Walther crossed the Dutch border wearing uniforms of the Dutch police and arrived two days later. When the Wehrmacht began operations at the bridge Meuse of Gennep, they realised that the Dutch had previously rigged it with explosives to prevent its use by the Germans, however overall there were no issues, Walther's group, pretending to escort German prisoners, took the guards by surprise from one side of the bridge and after a brief confrontation three Germans were wounded and the platoon took possession of the station; the Dutch guards on the other side of the bridge in a confused scramble, left the Germans too close to their objective, and they had no difficulty completing the conquest of the bridge, on which the Wehrmacht tanks passed shortly afterwards. At the same time, other Brandenburg units seized several bridges over the Juliana Canal—also in the Netherlands, while their fellow soldiers entered Luxembourg, occupying bridges over the Our (river) and in Belgium carrying out similar actions. Chronicling Brandenburger No. 3 Company's penetration into Belgium, Lahousen was gratified to report that, "forty-two out of sixty-one objectives were secured and handed over to the units following behind." For their exploits in Belgium and the Netherlands, the Brandenburgers were among the most decorated units marching with the invading German armies, which earned them the admiration of the Abwehr Chief, Wilhelm Canaris. On 27 May 1940, chief-of-staff of the High Command of the German armed forces, Wilhelm Keitel, wrote to Canaris that the Brandenburgers had "fought outstandingly well" which was further validated when Hitler presented Iron Cross commendations to 75 percent of the 600 men who participated. By October 1940, the Brandenburgers constituted an entire regiment-sized unit.

Output:
