The Spanish casualties were about 1,200[20] and British casualties were 6,268, including 800 killed, over the two days of fighting.[6][21] This was approximately 25% of the British force, compared to only 18% of the French, although it is clear that the brunt of the French attack fell on the British. Many of the wounded on both sides were burnt to death when the dry grass of the battlefield caught fire. The next day, the 3,000 infantry of the Light Division reinforced the British army after completing a famous march of 42 miles (68 km) in 26 hours.
