Question: Where did troops first invade in the country where the The Monument aux Morts de Montauban creator had citizenship?

<P0-S0> patuxai (lao: ປະຕູໄຊ, literally meaning victory gate or gate of triumph, formerly the anousavary or anosavari monument, known by the french as monument aux morts) is a war monument in the centre of vientiane, laos, built between 1957 and 1968. the patuxai was dedicated to those who fought in the struggle for independence from france. <P0-S1> in romanising the name from the laotian language, it is variously transliterated as patuxai, patuxay, patousai and patusai. <P0-S2> it is also called patuxai arch or the arc de triomphe of vientiane as it resembles the arc de triomphe in paris. <P0-S3> however, it is typically laotian in design, decorated with mythological creatures such as the kinnari (half-female, half-bird). <SEP> <P1-S0> by 1940 the third reich had occupied many of the alpine countries. <P1-S1> austria underwent a political coup that made it part of the third reich; france had been invaded and italy was a fascist regime. <P1-S2> switzerland was the only country to luckily avoid invasion. <P1-S3> the swiss confederate mobilized its troops—the country follows the doctrine of "armed neutrality" with all males required to have military training—a number that general eisenhower estimated to be about 850,000. the swiss commanders wired the infrastructure leading into the country, and threatening to destroy bridges, railway tunnels and passes in the event of a nazi invasion, and then they retreated to the heart of the mountain peaks where conditions were harsher and a military invasion would involve difficult and protracted battles. <SEP> <P2-S0> According to some historians, Bismarck adroitly created a diplomatic crisis over the succession to the Spanish throne, then edited a dispatch about a meeting between King William of Prussia and the French ambassador, to make it appear that the French had been insulted. <P2-S1> The French press and parliament demanded a war, which the generals of Napoleon III assured him that France would win. <P2-S2> Napoleon and his Prime Minister, Émile Ollivier, for their parts sought war to solve their problems with political disunity in France. <P2-S3> The German coalition mobilised its troops much more quickly than the French and rapidly invaded northeastern France. <P2-S4> On 16 July 1870, the French parliament voted to declare war on the German Kingdom of Prussia and hostilities began three days later. <P2-S5> The German forces were superior in numbers, had better training and leadership and made more effective use of modern technology, particularly railroads and artillery. <SEP> <P3-S0> The Monument aux Morts de Montauban is an 1894 sculpture by Antoine Bourdelle. <P3-S1> His romantic vision of the monument generated many violent oppositions. <P3-S2> Auguste Rodin's intervention in 1897 enabled Bourdelle to do this sculpture without any compromise. <P3-S3> The monument was erected in Montauban, in the department of Tarn-et-Garonne, in 1902. <SEP> <P4-S0> His studio became the Musée Bourdelle, an art museum dedicated to his work, located at 18, rue Antoine Bourdelle, in the 15th arrondissement of Paris, France.
