On 16th March, 1968 Warrant Officer Hugh Thompson Jnr was flying helicopter reconnaissance for an attack on an alleged North Vietnamese-controlled village at My Lai.

As the ground attack developed below, Thompson realised he was in fact witnessing something something else:

A massacre.

He decided to act. /1 🧵 #history #histodons

At first Thompson and his crew, Lawrence Colburn and Glen Andreotta thought the wounded Vietnamese they saw below them were the result of artillery fire.

They dropped a green flare near a wounded civilian, expecting the infantry to help. Instead, Captain Medina of Charlie Company walked over and shot her in the head. /2

@garius What a great thread. Thank you. I'm currently listening (again) to Max Hastings account of Vietnam. What a march of folly. No lessons learnt, either.
