Two World War II liberators, ages 101 and 97, still teaching what freedom cost. As John puts it, freedom is a receipt.

In Bastogne the war stays behind the fence. In Kyiv the alerts keep sounding. John on the systems that only hold if we maintain them.

Deep snow, German guns on the ridge, and the 508th Parachute Infantry going uphill anyway. John on a Bulge battle few remember.

Today's 101st Airborne soldiers walked the ground their predecessors held at Bastogne, connecting the Bulge's lessons to modern leadership.

Harry Miller lied about his age to join the Army, passed shells in a Sherman at the Bulge, and later helped plan B-52 strikes. Lunch with a living history book.

Under siege at Bastogne, a 19-year-old paratrooper carried beer to wounded friends in his helmet. Decades later, it became a Belgian legend.

A Bicentennial train ride at 13 and a snowy staff ride through the Ardennes years later taught John the power of standing where history happened.

A former boxer and merchant seaman, Sgt. Jose Lopez held off a German attack at Krinkelt with a heavy machine gun and saved his company.
