The British government feared the powerful Danish fleet was about to fall into French hands and thus delivered Denmark an ultimatum to sail its fleet to Britain or face war with Britain.
The Danes refused to sail it to Britain and so British troops landed at Vedbæk on 16 August and began to bombard Copenhagen.
Generalløjtnant Castenschiold was ordered to create a frikorps and rescue Copenhagen.
The foot soldiers were organized into the 5th, 6th and 7th Battalions of the North Zealand Landvaern, the 1st, 2nd, 4th, 5th, 7th, 8th, 9th and 10th Battalions of the South Zealand Landvaern.
Colonel Wilhelm von Linsingen was Wellesley's brigade commander.
Castenschiold's force was made up of 7,000 infantry in 11 battalions, 150 cavalry in two squadrons, and 120 artillerists serving nine guns.
In the meantime the British headquarters at Copenhagen had gained had become aware of the Danish militia's mobilisation and on 27 August general Arthur Wellesley (later 1st Duke of Wellington) was ordered to find and defeat it.
Wellesley's 6,000-man Anglo-German infantry force included the 1st Battalion of the 43rd Foot, the 2nd Battalion of the 52nd Foot, the 1st Battalion of the 92nd Foot, five companies from the 1st and 2nd Battalions of the 95th Foot, and the 6th Line Battalion King's German Legion.
