Allen Apsley (Royalist) but presumably Apsley's was at Newbury due to its good strength compared to the other regiments in the tercio. On 29 May 1645, Apsley's and the rest of Astley's tercio made up the right flank at the storming of Leicester, which fell the next day in a bloody massacre to the royalist cry of "Kill Dead!" It is presumed by this point that Apsley's horse had either gone back to Exeter with Allen or been amalgamated into one of the other horse regiments as no further records of them exist. By the Battle of Naseby on 14 June 1645, what
Battle of Selby fairly short order the town fell. With the fall of the town huge stocks of munitions and more than 1,500 Royalist soldiers were lost to the Parliamentarians. The road from Hull to York was now opened for a Parliamentary advance on York, which they were able to besiege. When Royalist forces under Prince Rupert, relieved York and combined with the garrisons forces, Rupert felt strong enough to engage in the pitched Battle of Marston Moor, however the Parliamentarians and Scottish Covenanters won the battle and with that victory consolidated their position in the north-east, depriving the Royalists of the area.
