The pals battalions of World War I were specially constituted battalions of the British Army comprising men who had enlisted together in local recruiting drives, with the promise that they would be able to serve alongside their friends, neighbours and colleagues ("pals"), rather than being arbitrarily allocated to battalions.
At the outbreak of World War I in August 1914, Lord Kitchener, the Secretary of State for War, believed that overwhelming manpower was the key to winning the war and he set about looking for ways to encourage men of all classes to join. This concept stood in direct contrast to centuries of British military tradition, in which the British Army had always relied on professional (rather than conscript) soldiers, and had drawn its members from either the gentry (for officers) or lower classes (for enlisted men). General Sir Henry Rawlinson suggested that men would be more inclined to enlist in the Army if they knew that they were going to serve alongside their friends and colleagues. He appealed to London stockbrokers to raise a battalion of men from workers in the City of London to set an example. Sixteen hundred men enlisted in this 10th (Service) Battalion, Royal Fusiliers, the so-called "Stockbrokers' Battalion", within a week in late August 1914.
Within two days, 1,500 Liverpudlians had joined the new battalion. Speaking to these men Lord Derby said: "This should be a battalion of pals, a battalion in which friends from the same office will fight shoulder to shoulder for the honour of Britain and the credit of Liverpool." Within the next few days, three more battalions were raised in Liverpool, forming the 17th, 18th, 19th and 20th Battalions of the King's Regiment (Liverpool).
Encouraged by Lord Derby's success, Kitchener promoted the idea of organising similar recruitment campaigns throughout the entire country. By the end of September 1914, more than fifty towns had formed Pals battalions, whilst the larger towns and cities were able to form several battalions each; Manchester, for example, raised four battalions in August, and four more in November. From the perspective of the War Office, the Pals battalion experiment relieved the heavy strain on the recruiting structure of a suddenly expanded regular army as well as easing the financial strain. In September 1914 Kitchener announced that the organizers of locally raised units would have to meet the initial accommodation and other costs involved, until the War Office took over their management. Accordingly, many recruits for the new Pals battalions were initially able to live at home while reporting for daily basic training.
