as many as possible of his colleagues and henchmen to visit him, to receive his ever-generous hospitality." In January 1928, James Lees-Milne stayed as a guest of Churchill's son Randolph. He described an evening after dinner; "We remained at that round table till after midnight. Mr Churchill spent a blissful two hours demonstrating with decanters and wine glasses how the Battle of Jutland was fought. He got worked up like a schoolboy, making barking noises in imitation of gunfire, and blowing cigar smoke across the battle scene in imitation of gun smoke". On 26 September 1927, Churchill composed the first of his Chartwell Bulletins, which were lengthy letters to Clementine, written to her while she was abroad. In the bulletins, Churchill described in great detail the ongoing works on the house and the gardens, and aspects of his life there. The 26 September letter opens with a report of Churchill's deepening interest in painting; "Sickert arrived on Friday night and we worked very hard at various paintings ... I am really thrilled ... I see my way to paint far better pictures than I ever thought possible before".

I built ... two cottages, ... and walls and made ... a large swimming pool which ... could be heated to supplement our fickle sunshine. Thus I ... dwelt at peace within my habitation". Bill Deakin, one of Churchill's research assistants, recalled his working routine. "He would start the day at eight o'clock in bed, reading. Then he started with his mail. His lunchtime conversation was quite magnificent, ...absolutely free for all. After lunch, if he had guests he would take them round the garden. At seven he would bathe and change for dinner. At midnight, when the guests left, then he would start work ... to three or four in the morning. The secret was his phenomenal power to concentrate." In his study of Churchill as author, the historian Peter Clarke described Chartwell as "Winston's word factory". In the opinion of Robin Fedden, a diplomat, and later Deputy General Secretary of the National Trust and author of the Trust's first guidebook for Chartwell, the house became "the most important country house in Europe".
