In the first hours of August 30, confronting the reality of his armyвЂ™s collapse, Samsonov went into the forest, away from his staff, and shot himself.

After three days of battering by German artillery, SamsonovвЂ™s troops began their retreat more German forces cut off their path and a massive slaughter ensued. The delay in starting the attack had given SamsonovвЂ™s forces more time to advance deeper into the sack formed by the German divisions enveloping them from both sides, the strength of which Samsonov consistently underestimated. On August 26, after intercepting wireless messages from both Samsonov and Rennenkampf, the Germans were able to take SamsonovвЂ™s army by surprise with the force of their attack near the village of Tannenberg, to the southwest of the Masurian Lakes. Though Ludendorff succumbed to nerves initially, delaying the start of the German attack by one day, Hindenburg was able to calm his subordinate-not for the last time in what would become a fabled partnership. Separated by the great Masurian Lakes, the two Russian armies were unable to effectively communicate with each other as to their movements, a circumstance that would prove deadly.
