Following the decimation of their air support based in Norway on the 25th, the British forces in central Norway found themselves under increasing pressure. In fierce fighting in the town of Kvam they faced an artillery barrage to which they had no reply, then a series of outflanking manoeuvres on the high ground around them which made their position increasingly precarious. Complete German air superiority meant that they could also bomb and strafe at will, supporting not just their front line forces but interrupting the British lines of communication and supply bases. While the forces on the ground were given instructions to hold on for a long as possible, with a view bringing in re-inforcements, London started to give serious consideration to evacuating the whole force.
