This collection of correspondence and newly discovered family papers is “a good read for anyone interested in WWI, or the British Army” (The NYMAS Review).   Hugo De Pree was the nephew of the better-known Field Marshal Sir Douglas Haig. However, De Pree had a distinguished military career in his own right. He served in the Boer War. He was sent to the Western Front, as Chief of Staff of IV Corps, and played a key part in planning the Battle of Cambrai in 1917.   In 1918 De Pree was appointed to command 189 Brigade in 63rd (Royal Naval) Division. His part in the March Retreat showed that he was not a chateau general. In August 1918, he took the morally courageous decision to cancel his Brigade’s attack, fearing heavy losses for little gain. He was sacked, but after appealing was appointed to command a brigade of 38th (Welsh) Division, which he commanded with distinction in the last weeks of the war. Afterward, De Pree rose to Major-General and was the Commandant at RMA Woolwich. His son, John, was killed in 1942 when attempting to escape from a POW camp in Germany, a story told in this book by one of the leading academics in the field, which combines De Pree and Haig family papers with incisive commentary to give a multi-faceted insight into both an important but obscure senior officer of the First World War, and his hugely famous uncle.
