July 6, 1936, Route 66, New Mexico. This is Martha Evans, 32. She had been walking for three days. Her husband died of tuberculosis in Oklahoma in May. The farm was foreclosed. She took the six kids and a Radio Flyer wagon and started west for California. The twins in the wagon were 11 months old. The boys walking were 6, 5, 4, and 3. Her dress was torn on barbed wire. Her leg was cut and infected. She wrapped it with a feed sack. She had $1.60 in her pocket. A photographer from the Resettlement Administration saw them and pulled over. He offered her a ride. She said no. She said if she took a ride now, the kids would expect one every time they were tired. She gave him her name and kept walking. The photo ran in newspapers across the country. Donations came to a PO box in Barstow. She got $200 and a bus ticket. She made it to Bakersfield and picked grapes. All six kids lived. Three went to college. Martha died in 1978. The wagon is in the Smithsonian.

On June 13, 1777, a 19-year-old French teenager landed on a beach in South Carolina, uninvited, to fight in someone else's war. He would become one of the most important men in American history. The Marquis de Lafayette was one of the richest young aristocrats in France. He had a beautiful wife, a fortune, and zero reason to risk any of it. But he believed in the American cause so fiercely that when the French king forbade him from going, Lafayette bought his own ship and sailed anyway. He literally went AWOL from a life of luxury to bleed for a country that didn't exist yet. Congress was annoyed at first. Another foreign officer looking for a paycheck? Then Lafayette offered to serve for free and pay his own way. That got their attention. He met Washington and the two formed one of the great father-son bonds in American history. Washington had no biological children. Lafayette named his only son George Washington Lafayette. He took a bullet in the leg at Brandywine and kept rallying the retreat. He was instrumental at Yorktown, the battle that won the war. He went home a hero on two continents. A foreign teenager believed in America before America did. 249 years ago today.
