You can read about the many ways to remember here.
In an area of The National Memorial Arboretum in Staffordshire, 2535 Sessile or Durmast oak trees have been planted to represent every British flagged merchant vessel lost to enemy action during the Second World War. Tree reference 19/109 is in honour of all those who served on board HMS Li Wo and my Great Uncle, Thomas Wilkinson, VC, who I wrote about here. The Arboretum is a unique place, peaceful and spiritual, a year-round centre of Remembrance. Do visit if you have the opportunity.
We will remember them.
