He was Liberal MP for St Ives for 6 years until his resignation in 1906 and was knighted in 1912 for services to shipping. His son came to Chernocke House from Twyford School.

On leaving Oxford he went to South Shields to study ship construction and engineering. After a further period in the offices of his father’s company in London and Cardiff he was appointed to the board of directors. On the outbreak of war, having joined the Cornish Squadron of the 1st Devon Yeomanry in 1912, he rejoined his regiment, being promoted Captain a fortnight later. In 1915, they went to the Dardanelles, and Captain Hain fell in action at Suvla Bay on November 11th 1915 when a shell hit his dug-out. He was buried in grave I.F.18 of Hill 10 Cemetery, Gallipoli.

At the outbreak, two ships were berthed in German ports and another was trapped in the Black Sea. A further eighteen vessels were lost to enemy action. Sir Edward was devastated when Teddy Hain was killed at Gallipoli, never fully recovering from the loss, and in June 1917 suffered a severe breakdown during an air-raid on London.
