BARCELONA being now under King Charles, the Towns of Gironne, Tarragona, Tortosa, and Lerida, immediately declar’d for him.  To every one of which Engeneers being order’d, it was my Lot to be sent to Tortosa.  This Town is situated on the Side of the River Ebro, over which there is a fair and famous Bridge of Boats.  The Waters of this River are always of a dirty red Colour, somewhat fouler than our Moorish Waters; yet is it the only Water the Inhabitants drink, or covet to drink; and every House providing for its own Convenience Cisterns to preserve it in, by a few Hours standing it becomes as clear as the clearest Rock-water, but as soft as Milk.  In short, for Softness, Brightness, and Pleasantness of Taste, the Natives prefer it to all the Waters in the World.  And I must declare in favour of their Opinion, that none ever pleas’d me like it.

This Town was of the greater Moment to our Army, as opening a Passage into the Kingdom of Valencia on one Side, and the Kingdom of Arragon on the other:  And being of it self tolerably defensible, in human Appearance might probably repay a little Care and Charge in its Repair and Improvement.  Upon this Employ was I appointed, and thus was I busy’d, till the Arrival of the Earl of Peterborow with his little Army, in order to march to Valencia, the Capital of that Province.  Here he left in Garrison Colonel Hans Hamilton’s Regiment; the Place, nevertheless, was under the Command of a Spanish Governor, appointed by King Charles.

While the Earl stay’d a few Days at this Place, under Expectation of the promis’d Succours from Barcelona, he receiv’d a Proprio (or Express) from the King of Spain, full of Excuses, instead of Forces.  And yet the very same Letter, in a paradoxical Manner, commanded him, at all Events, to attempt the Relief of Santo Mattheo, where Colonel Jones commanded, and which was then under Siege by the Conde de los Torres (as was the Report) with upwards of three thousand Men.  The Earl of Peterborow could not muster above one thousand Foot, and about two hundred Horse; a small Force to make an Attempt of that Nature upon such a superior Power:  Yet the Earl’s Vivacity (as will be occasionally further observ’d in the Course of these Memoirs) never much regarded Numbers, so there was but room, by any Stratagem, to hope for Success.  True it is, for his greater Encouragement and Consolation, the same Letter intimated, that a great Concourse of the Country People being up in Arms, to the Number of many Thousands, in Favour of King Charles, and wanting only Officers, the Enterprize would be easy and unattended with much Danger.  But upon mature Enquiry, the Earl found that great Body of Men all in nubibus; and that the Conde, in the plain Truth of the Matter, was much stronger than the Letter at first represented.
