The handover of the base to Afghan control ends an important chapter in the 13-year campaign, which started after the terrorist attacks on the US in 2001.
Helmand was a major focus of a troops surge to wrest control back from the Taliban in 2006. At its height, the Nato-led force had some 140,000 military personnel from nearly 50 nations. Camp Bastion and Camp Leatherneck alone once had 40,000 military personnel and civilian contractors as the regional headquarters for the international military coalition.
Britain suffered 453 fatalities during the campaign. The vast majority of the fatalities happened in Helmand province.
