On 25 February, the Germans occupied Douaumont. French reinforcements—now under the leadership of General Philippe Pétain—began to arrive and were instantly thrown into "the furnace" (as the battle was called) to slow the German advance, no matter what the cost. Over the next several days, the stubborn defense managed to slow the German advance with a series of bloody counter-attacks. In March, Falkenhayn decided to target the French positions on the left bank of the Meuse as well, broadening the offensive front twofold. Throughout March and April, Cumières-le-Mort-Homme and Hill 304 were under continuous heavy bombardment and relentless infantry attacks. Meanwhile, Pétain organised repeated, small-scale counter-attacks to slow the German advance. He also ensured that the sole supply road from Bar-le-Duc into Verdun remained open. It became known as the Voie Sacrée "Sacred Way" because it continued to carry vital supplies and reinforcements into the Verdun front despite constant artillery fire.
