 suspected an American attack in the vicinity of Cisterna and sent a large force of crack troops, armored units, and artillery to cut off the Rangers.

On the night of January 30, 1944, the 1st and 3rd Ranger Battalions made their way behind enemy lines and killed the German sentries in Cisterna. Suddenly, concealed German artillery and armor opened fire on the Americans. One of the first shells killed Major Miller, the 3rd Battalion commander. Major Dobson, the 1st Battalion C.O., took command of the two battalions. The Rangers took cover and started firing, but rifles were no match for the heavy German equipment. All of the Rangers fought bravely, killing a good number of Germans, but they suffered many more killed and wounded. Major Dobson was among the wounded.

When Colonel Darby, Colonel Dammer, and the other staff officers in the 6615th Headquarters found out about the plight of the 1st and 3rd Battalions, Major Walter Nye, the 4th Battalion's acting commander, was ordered to bring his men up the road to rescue the other two battalions. The battalion, with armored and infantry support, fought a bitter, bloody battle with the Germans. Many Germans were killed in the two-day battle that followed. However, the relief force was stalled too long to be of much help to their fellow Rangers. Out of the 767 Rangers who made it into Cisterna, only 6 made it out. The rest were killed or captured.

After Cisterna

Cisterna marked the end of the 6615th as a complete unit. The 4th Battalion was assigned to the 1st Special Service Force and Colonels Darby and Dammer were given different assignments. Darby eventually became assistant division commander of the 10th Mountain Division
