I must acknowledge my self one of that Number; and therefore in the Year
1674,1 resolv'd to go into _Flanders_, in order to serve as Voluntier in
the Army commanded by his Highness the Prince of _Orange_. I took my
Passage accordingly at _Dover_ for _Calais_, and so went by way of
_Dunkirk_ for _Brussels_.

Arriving at which Place, I was inform'd that the Army of the
Confederates lay encamp'd not far from _Nivelle_; and under the daily
Expectation of an Engagement with the Enemy. This News made me press
forward to the Service; for which Purpose I carry'd along with me proper

Major-General. Upon further Enquiry I understood, that a Party of Horse,
which was to guard some Waggons that were going to Count _Montery's_
Army, were to set out next Morning; so I got an _Irish_ Priest to
introduce me to the Commanding Officer, which he readily oblig'd me in;
and they, as I wish'd them, arriv'd in the Camp next day.

got over our Heads almost as soon as seen. When the Skirts of that Cloud
began to cover our Camp, there suddenly arose such a terrible
Hurricaine, or Whirlwind, that all the Tents were carry'd aloft with
great Violence into the Air; and Soldiers' Hats flew so high and thick,
that my Fansy can resemble it to nothing better than those Flights of
Rooks, which at Dusk of Evening, leaving the Fields, seek their roosting
Places. Trees were torn up by the very Roots; and the Roofs of all the
Barns, _&c._ belonging to the Prince's Quarters, were blown quite away.
This lasted for about half an Hour, until the Cloud was wholly past over
