Even when Henry's misfortunes were at an end, and when the Battle of Evesham was won, the Tower was perpetually unfortunate. A body of rebels surrounded it, and in the defence were present a great number of Jews, who had fled from the fighting in the city only to find themselves pressed for service in defence of the fortress. From that moment they make no further appearance in English military history till the South African War, unless indeed their appearance in chains thirteen years later in this same Tower as prisoners for financial trickery can be counted a military event.

Upon this occasion the siege was raised by the promptitude and energy of Prince Edward—the man who as King was to march to Cærnarvon and to the Grampians had already in his boyhood shown the energy and the military aptitude of his grandfather King John. He was but twenty years old, yet he had already done all the fighting at Lewes, he had already won Evesham, and now, at the end of spring, he made one march from Windsor to the Tower and relieved it. It was almost the last time that the Tower stood for the success of authority. From this time onwards it is, as it had been before, the unfortunate symbol of successful rebellion. Edward II. had to leave it in his fatal year of 1326, the Londoners poured in and incidentally massacred the Bishop of Exeter, into whose hands it had been entrusted.

In 1460 it surrendered to the House of York, and from that time onwards becomes more and more of a prison and less and less of a fortress.

The preponderatingly military aspect of the Thames Valley in English history dwindles with the dwindling of military energy in our civilisation, and passes with the passing of a governing class that was military rather than commercial.

Sites which owed their importance to strategical position, and which had hence grown into considerable towns, ceased to show any but a civilian character, and even in the only episode of consequence wherein fighting occurred in England since the Middle Ages—the episode of the Civil Wars—the banks of the Thames, though perpetually infested by either army, saw very little serious fighting, and that although the line of the Thames was the critical line of action during the first stage of the war.

For the Civil Wars as a whole were but an affair upon the flank of the general struggle in Europe: the losses were never heavy, and in the first stages one can hardly call it fighting at all.

The losses at the skirmish of Edge Hill were, indeed, respectable, though most of them seem to have been incurred after the true fighting ceased, but with that exception, and especially upon the line of the Thames itself, the losses were extraordinarily small.

One may say that Oxford and London were the two objective points of the opposing forces from the close of 1642 to the spring of 1644. The King's Government at Oxford, the Parliament in London, were the civil bases, at least, upon which the opposing forces pivoted, and the two intermediate points were Abingdon and Reading. To read the contemporary, and even the modern, history of the time, one would imagine from the terms used that these places were the theatre of considerable military operations. We hear, with every technicality which the Continental struggle had rendered familiar to Englishmen, of sieges, assaults, headquarters, and even hornworks. But when one looks at dates and figures it is not easy to treat the matter seriously. Here, for instance, is Abingdon, within a short walk of Oxford, and the Royalists easily allow it to be occupied by Essex in the spring of '44. Even so Abingdon is not used as a base for doing anything more serious than "molesting" the university town. And it was so held that Rupert tried to recapture it, of all things in the world, with cavalry! He was "overwhelmed" by the vastly superior forces of the enemy, and his attempt failed. When one has thoroughly grasped this considerable military event one next learns that the overwhelming forces were a trifle over a thousand in number!

Next an individual gentleman with a few followers conceives the elementary idea of blocking the western road at Culham Bridge, and isolating Abingdon upon this side. He begins building a "fort." A certain proportion of the handful in Abingdon go out and kill him and the fort is not proceeded with: and so forth. A military temper of this sort very easily explains the cold-blooded massacre of prisoners which the Parliament permitted, and which has given to the phrase "Abingdon Law" the unpleasant flavour which it still retains.

The story of Reading in the earlier part of the struggle is much the same. Reading was held as a royal garrison and fortified in '43. According to the garrison the fortification was contemptible, according to the procedures it was of the most formidable kind. Indeed they doubted whether it could be captured by an assault of less than 5000 men, a number which appeared at this stage of the campaign so appalling that it is mentioned as a sort of standard of comparison with the impossible. The garrison surrendered just as relief was approaching it, and after a strain which it had endured for no less than ten days; but the capture of Reading was not effected entirely without bloodshed; certainly fifty men were killed (counting both sides), possibly a few more; and the whole episode is a grotesque little foot-note to the comic opera upon which rose the curtain of the Civil Wars. It was not till the appearance of Cromwell, with his highly paid and disciplined force, that the tragedy began.
