At a time when throughout the rest of Europe armies were manoeuvring against one another with no more than a formal result, the English and Scots were fighting decisive battles; and Cromwell's battles were more decisive than those of any other leader.
He allied himself with the Republican party on its organization, but his inborn dislike for political manoeuvring prevented his ever becoming prominent in its councils.
After the conclusion of the peace of Nicias (421 B.C.) he marched against the Argives in defence of Epidaurus, and after skilful manoeuvring surrounded the Argive army, and seemed to have victory within his grasp when he unaccountably concluded a four months' truce and withdrew his forces.
The strength of the army lay in its infantry, for both cavalry and artillery were short of horses, and the latter had not yet acquired mobility and skill in manoeuvring.
The opportunity for this concentration he owed to the time gained for him by his rearguard at Joukendorf, for this had stood just long enough to induce the French columns to swing in to surround him, and the next day was thus lost to the emperor as his corps had to extend again to their manoeuvring intervals.
