Question:  Childersburg, Alabama is near the munitions plant that was operated during what event?
Context: Deutsche Waffen- und Munitionsfabriken Aktien-Gesellschaft (German Weapons and Munitions public limited company), known as DWM, was an arms company in Imperial Germany created in 1896 when "Ludwig Loewe & Company" united its weapons and ammunition production facilities within one company.  In 1896 Loewe founded Deutsche Waffen- und Munitionsfabriken with a munitions plant in Karlsruhe (Baden), formerly Deutsche Metallpatronenfabrik Lorenz, and the weapons plant in Berlin.  Shares that Loewe had in other gun- and ammunition plants were transferred to DWM.  This included Waffenfabrik Mauser, Fabrique Nationale d'Armes de Guerre (FN) in Belgium and Waffen- und Munitionsfabrik A.G. in Budapest.  The DWM was orchestrated by Isidor Loewe (1848–1910), as his brother Ludwig had died in 1886.  Karl Maybach (who was part of the Maybach company) was employed by the Loewe company in 1901.
