This image is a Parliamentary illustration titled "The English and Scotts Armies at first ready to fight lovingly embrace each other and part kinde friends". It depicts a scene related to the Pacification of Berwick during the Bishops' Wars in 1639, where the two armies negotiated a truce instead of engaging in battle.
