Handley Page O/100 and O/400 specifications and other notes
In the early hours of May 10th, 1918, seven Handley Pages of No. 214 Squadron co-operated with Naval forces in the attempt to block Ostend harbor. The bombers dropped six 550-lb, fifty-three 112-lb, and twenty-six 25-lb bombs on the German batteries. The same squadron was requested on May 16th to bomb Bruges on every possible occasion, but by the end of the month No. 214 had only six serviceable Handley Pages and the target suffered less than it ought to have done.
