I have been revisiting the process that ended with my dad being taken prisoner on 20th May 1940. I have the page in his units war diary that reveals his troop along with another was overun before they could be evacuated. The delay was caused by their lorries being used to evacuate the guns of 210 AA Battery. I have found out that 210 Bty was attached to 60 AA regt part of 2 AA brigade from its original deployment in 73 AA regt part of 12 AA brigade. Does anyone know the correct war diary ref at NA for this unit at this period. I have attached the wording from the war diary of 8 Bty 2 S/L Regt RA as it appears. Many Thanks
