This is a release of a former Patreon-only episode.    The Germans and Russians are ready to fight, and each gives battle. The Russian 1st Army invades East Prussia from the east, and meets German 8th Army forces at Stallupönen. Both sides clash again at Gumbinnen, where the Germans suffer a stinging defeat that sets off a panic within 8th Army headquarters.    The BFWWP is on Patreon: https://www.patreon.com/BattlesoftheFirstWorldWarPodcast.    Any questions, comments or concerns please contact me through the website, www.firstworldwarpodcast.com.
