The Brigade was formed by the Polish High Command in exile with the aim of its being used to support the Polish resistance during the nationwide uprising, a plan that encountered opposition from the British, who argued that a single brigade would be of no use against the entire German army stationed in Occupied Poland. The pressure of the British government eventually caused the Poles to give in and agree to let the Brigade be used on the Western Front. On 6 June 1944 the unit, originally the only Polish unit directly subordinate to the Polish government in exile and thus independent of the British command, was transferred into the same command structure as all other Polish Forces in the West. It was slotted to take part in several operations after the invasion of Normandy, but all of them were cancelled. On 27 July, aware of the imminent Warsaw Uprising, the Polish government in exile asked the British government for air support, including dropping the Brigade in the vicinity of Warsaw. This request was refused on the grounds of the aircraft used by the Brigade did not have enough fuel to reach Warsaw, along with the request to use Soviet airfields being denied. Eventually, the Brigade entered combat when it was dropped during Operation Market Garden in September 1944.
