hi stella
no it wasn't me. My friend chris ("Njaco") was the person that found that information and posted it. I have an entry 1 june 1940 in that thread for the events affecting the BEF and French forces trapped in the encirclement on that day. But I did not mention your grandfathers name in my account.
By 1 June the allies were being placed under extreme pressure and the commanders on the spot were doubtful they could hold the perimeter much longer. At the evacuation points, the ships and embarkation points were by this stage under near continuous attack. It is not an exaggeration to equate what was happening to Dante's vision of hell. Despite this, the defenders, both French and British, held their nerve and fought hard to keep the germans at bay for several more days. it was, as they say, one of those miraculous moments in history.
