Lincolnshire played a major part in the First World War on land, at sea, and in the air through men serving in the forces and the munitionette women who stayed behind.
A substantial proportion of Lincolnshire men enlisted to join the British Army's principal unit in the region, the Lincolnshire Regiment. The Lincolnshire Regiment had 10 battalions that saw active service during the First World War and the unit won 69 battle honours between 1914 and 1918.
Many men also joined the Lincolnshire Yeomanry, a local cavalry regiment that served with distinction in the Middle East and on the Western Front. Men from Lincolnshire also joined the Royal Navy in significant numbers and sailors from the county served in all of the major engagements of the early months of the war.
It was during the First World War that Lincolnshire's links with the RAF were first forged. Prior to the establishment of the RAF in April 1918, Britain's military aircraft were controlled by two separate organisations, the Royal Naval Air Service (RNAS) and the Royal Flying Corps (RFC) - a station of which is still found at Cranwell.
Lincoln also made an immense contribution to the war effort through the production of military equipment. The first tanks were designed and built by William Foster & Company, a Lincoln-based firm of agricultural engineers. Lincoln was one of the five biggest centres for aircraft production, the city firm of Ruston & Proctor produced more aircraft engines than any other British company.
Lincolnshire women also made a vital contribution to the war effort and became known as "munitionettes". With so many men away, women took on a very wide range of manufacturing roles.
