New Street and Friar Street, where traces of it can still be seen in places, it reached Friar's Gate, which stood at the back of the old City Gaol, now the site of Laslett's Almshouse Charity, Union Street, formerly a Dominican House. The wall then went along at the back of Friar Street until it reached Sidbury. Here, just on the city side of the modern Sidbury Bridge over the canal, stood the main south gate of the city, the Sidbury Gate. The wall then ran south of Saint Peter's Church (Saint Peter's Street), across the site of the Porcelain Museum, until it reached the gate known as Frog Gate (on what was Frog lane and is now Severn Street). The wall then ran north-west joining onto a covered way that led to the Castle Hill. From this came another wall which ran down the lower part of Severn Street, until it reached the river (close to the Diglis House Hotel). A new wall started here, turning up by the side of the river to the north. This was not, however, so strong or so important a wall as that on the other side of the city. Soon after the wall left the Diglis Hotel area, just below the cathedral, it reached the Priory Gate. From this the wall ran on to the end of Newport Street, where it joined the Bridge Gate. It would appear that there was no ditch from this point to where the wall left the Foregate Street to Lowesmoor; at a later date an attempt was made to remedy this. Extra fortifications were placed on this part of the wall, but it always remained a weak spot in the city's defences. Worcester was occupied by Sir John Byron on 16 September 1647, who was on his way to deliver wagons of silver plate from Oxford to the Charles I at Shrewsbury. Byron realising that he could not hold the Worcester with a Parliamentary army under the command of Earl of Essex already approaching city, he had sent a request to the King for additional forces to aid him. The Parliamentarians were aware of Byron's mission and an advanced force under the command of Colonel Nathaniel Fiennes arrived at the Sidbury Gate early on 22 September. What followed was typical of the inexperienced soldiery on both sides. The Parliamentarians were not challenged as they approached the
