Newbury and Marston Moor, are now in the British Museum. Dutch and German engineers also abounded on the parliamentary side. One of the best known is Lieutenant-Colonel John Rosworm, who fortified Manchester for the Parliament, helped to capture Liverpool Castle, and wrote a narrative called _Good Service hitherto ill-rewarded_, setting forth his difficulties in obtaining his pay. In Essex's army Philibert Emmanuel du Boys held the post of Lieutenant-General of the Ordnance, whilst in the New Model Peter Manteau Van Dalem was Engineer-General. The names of Cornelius and Chrystoph Van Bemmell appear in the Parliamentary Army Lists in 1648, and in 1649 Joachim Hane begins to be mentioned. Fortunately, the English portion of Hane's career can be traced with tolerable fullness. He was born at Frankfort on the Oder, and was therefore by birth a subject of the Elector of Brandenburg. In his army, or in some other foreign army, Hane obtained his military education. Probably he was one of the many soldiers cast adrift by the disbanding which followed the peace of Westphalia, and obliged thereby to seek employment outside Germany. He appeared in England first in 1649, and was employed by the Council of State to report on the fortifications of Weymouth with a view to the building of a citadel there. He was also sent to Yarmouth to consult with the governor and the officers of the garrison on the erection of a fort[1]. In the following year Hane seems to have accompanied Cromwell in his expedition to Scotland, and he remained in Scotland with Monk when Cromwell marched into England. The surrender of Stirling Castle to Monk was mainly due to Hane's skill as an artilleryman. On August 13, says the diary of the siege, 'the morter-pieces were planted, and Mr. Hane, the engineer, plaid with one of the morter-pieces twice. The second shot fell into the middle of the Castle, and did much execution. Afterwards he played with the other great morter-piece and did execution.' On the 14th the garrison, who were not accustomed to shells, mutinied and forced the governor to surrender. Again, a fortnight later, at the siege of Dundee, the same narrative records that 'Mr. Hane, the engineer, plaid the morter-piece.' December following Hane was sent to Inverness to report on its possibilities as a fortress, and returned with the news that it was 'not fortifiable without a great deal of charges, nor tenable without a greater number of men than the town can possibly provide accomodation for.' The result was that instead of fortifying the town itself a fort large enough to hold 2000 men was built close by it. In 1653 Hane was again in England, though Colonel Lilburne, the Commander-in-Chief in Scotland, was writing letter after letter to the Lord-General to demand his return. Many officers, complained Lilburne, have been absent a long time from their charges: 'and in particular Mr. Hane, the Engineer, of whom wee have an exceeding great want, and I doe wonder hee should
