Very cool screenshots and exciting reports! The first Roland C.IIs did come into service in late 1915/early 1916, and were pretty good machines for their time, being able to outrun most opponents and having a very sturdy construction. However, the Roland had a nasty spin and landing accidents were common, thanks to terrible downward visibility from the cockpit.
"Upon my word I've had as much excitement on a car as in the air, especially since the R.F.C. have had women drivers."
