By the 19th the surviving fragments of the battalions reached their destination on the Yssel, where they were cantoned on the west side of the river from Zutphen to the sea. But there was no hope of long repose for them there. Harcourt perceived clearly that the re-embarkation of his force was now the only resource left to him, and that the place of embarkation must be on the Weser, since the lack of supplies and the incapacity of his commissariat-officers would inevitably forbid him to remain long on the Ems. Within a week, want of victuals and the hostility of the inhabitants compelled him to continue his retreat from the Yssel; ◆Jan. 27–29.◆ and on the 27th the march eastward was resumed, the main body of the British retiring towards Osnabrück, the Germans upon Münster. One detachment of British,[290] however, was sent northward under Lord Cathcart’s command to fetch a compass through West Friesland and along the borders of Groningen, in order to ascertain whether the people of these provinces were as ill-affected as their fellows towards the House of Orange. By whose orders this isolated force was despatched upon such an errand is uncertain; it is only known that the column was followed up and incessantly harassed by the enemy, and that it was not very successful in discovering friendly sentiments among the Dutch. Upon reaching the Ems, the army halted, and on the 5th February took up cantonments on the western bank of the river, Cathcart on the extreme north guarding the passes of the Bourtanger Moor from the Dollart southward, while Abercromby fixed his headquarters further to south and west of the river at Bentheim, and the Hanoverians retired to Münster.
