World War II
In late 1944, Hamilton was a Major and temporary Commanding Officer of the 11th Battalion of the Durham Light Infantry. At that time the battalion was broken up with the soldiers and officers dispersed as reinforcements to other units. Hamilton was transferred to the Duke of Wellington's Regiment 1/7th Battalion, as second in command under Lt Col Wilsey, in November. During December when the battalion was stationed at the bridgehead at Nijmegen he took temporary command of the 1/7th, on 2 December, whilst Wilsey took temporary command of the Brigade for a week. On the day he took command the battalion came under attack from German units at Haalderen, in an attempt to retake the bridge. A German officer, 2/Lt Heinich, 5 Coy 16 Parachute Regiment 6 Parachute Division, was captured by members of 'B' company, who were laying trip flares. Hamilton quickly organised a defence, using his Bren Gun Carriers to hold back the Germans. The attack continued for several days during which the battalion received heavy artillery and mortar fire. Large numbers of prisoners were taken from the 5th, 7th and 10th companies of the German 16 Para Regiment. Fighting intensified, taking in house to house action throughout Haalderen, where the German forces took heavy losses in killed and wounded. 'D' company of the Royal Scots Fusiliers moved in to support the 1/7th on 4 December. German artillery fire intensified on the battalion positions. By 7 December the main attack had been repulsed, though artillery, mortar and sniper attacks continued until the battalion was withdrawn to Nijmegen on 22 January. For his actions and leadership Hamilton was awarded a DSO. A few weeks later, in January 1945, Hamilton was promoted to Lieutenant Colonel and took command of the 1/7th Battalion, when Lt Col Wilsey became the Brigade Commander.
In 1959, he became editor of the Sunday Times. He later became editor in chief and chairman of Times Newspapers Ltd., a group that included The Times. During this period, Hamilton struggled with production unions over staff cutbacks and the introduction of computer technology. He also introduced the colour magazine supplement into weekly national newspapers in England. He was knighted in 1976. From 1978 to 1983, he served as president of the International Press Institute. In 1979 he became chairman of Reuters until his retirement in 1985.
