1689. "In the month of January I was made a Lieutenant in the Prussian Guards, and the same year went with my Colonel, Baron Truckis, who made a campaign as voluntier on the Rhine. I was in the month of March in action of Niews, a little town between Keyserwart and Cologne, where the Brandenburghers totally beat the French and took all their baggage. In the month of June I was at the Siege of Keyserwart, which place the Brandenburghers, after some days' bombardment, took from the French by capitulation. In the month of July we marched with the Army from Keyserwart to invest the town of Bonn, which place was without intermission eight nights and days bombarded, and totally destroyed. After the bombardment it was kept blockaded till the month of September. In this bombardment I commanded two mortars ordered me by Colonel Wyller, commander of the Prussian Artillery. In the month of August I went from Bonn to Mentz, a town besieged by the Emperour's and Allies' Army. In the taking of the Counterscarps or Glacies of this place, it cost us near 4000 men, by which means the town was obliged to capitulate. In the month of September the Duke of Lorrain went with 10,000 men from Mentz, to reinforce the Allies' Army at Bonn. By his arrival there the attack was regularly carried on, in which service I was employed as Engineer, under the direction of Colonel Gore, who had the direction of the trenches carried on by the Dutch forces. The Counterscarps or Glacies, with a ravelin and a counterguard, were taken sword in hand with the loss of 3000 men. The enemy was beat into the town, which obliged them in two days' after to capitulate.

1691. "In the month of March 8000 of the Prussian troops were ordered to Hungary. The company to which I belonged was included in this number. We joined the Emperour's Army in the month of June, and we fought a Battle with the Turks at a place called Solankeman, where we beat them totally, and took upwards of 100 pieces of cannon, with a great part of their baggage, in the month of August.

1692. "I quitted the Prussian service, and agreed with Count de Dohna for a Company of Foot, in a Regiment of Foot he was to raise for the service of the Emperour. After some weeks spent in raising men for my company, the capitulation broke off, because the Emperour would not agree to the terms stipulated with the said Count. In the month of April I went from the city of Dantzick to Holland, and from thence in company with some Danish voluntiers to ye Siege of Namur. After the siege I went from Namur to the English and Allies' camp at Melle, and from thence I marched with the Army to the camp at Genap, where in the month of July I entered as Firemaster into the English Artillery, under the command of Colonel Gore.

"In the English Service.

1692. "I marched with the English Artillery to the Battle of Steenkirke, and after the battle was ordered with a Detachment of Fireworkers to joyn at Ostend those Artillery people which came from England under the command of Sir Martin Beckman. From Ostend we marched to Tourney, from thence to Dixmud, and at last to quarter at Ghent.

1693. "I was commanded with a Detachment of Fireworkers and Bombardiers to Liege, and from thence back again to Nearhespe, where we fought the battle of Landen, and where our Army was beat, and sixty-three pieces of English cannon lost. After the battle I was ordered with a detachment of Fireworkers to Sasvangand, in order to embark the great Artillery for a secret expedition; after some days' labour was ordered back again to the Army encamped at Nuioven, from thence into Flanders.

1694. "I went with my Lieutenant-Colonel Browne to the Siege of Huy, which place we took from the French in the month of September, by capitulation.

1695. "I was ordered with some mortars to follow the Duke of Wirtemberg, who commanded a detachment of the Army at Fort Knock invested by the said Duke. From thence I was ordered with a detachment of the Artillery to the Siege of Namur, which place I bombarded with twelve great mortars, and did throw about 4000 bombs (into the town, Cohorn's Work, and Terra Nova), before the siege was over. The town capitulated in August, and Cohorn's Work and Terra Nova in September.

1696. "Nothing material was done this year but making intrenchments, marching, and counter-marching with the Army.

1697. "This year was like the former till we encamped at Brussels, where the cessation of arms was proclaimed.... In the month of September the Army marched into quarters, where the greatest part of the Artillery people were ordered to England, foreigners excepted, who were all discharged except myself and one by name Schlunt. I was ordered to embark all the English Artillery remaining in Flanders to be sent to England. I myself went with the last embarkation in the month of February."
