The squadron left Kelly Field on 22 August 1917, arriving at the recruiting depot at Leaside, Toronto on the evening of the 25th.

In Canada, the squadron was trained in aircraft construction, overhaul, upkeep, motor transport work, aerial gunnery and other skills.

New orders were received and the 28th was transferred to Everman Field (#1), Camp Taliaferro, near Fort Worth, Texas, for additional RFC training.

Late in December, flying training practically ceased on account of cold weather and rumors abounded about being sent overseas.

[3] On 21 January 1918 the squadron was ordered to proceed to Garden City, Long Island, New York for overseas deployment.

Due to an epidemic of fever, the squadron was immediately quarantined, although the men was allowed to spend time in New York City as passes were plentiful.

Finally on 25 February, the squadron was embarked on the troop transport HMS 527, better known as the White Star Liner RMS Olympic[9] at New York Harbor, Pier 54.

That afternoon, all on board were suddenly alarmed by a heavy explosion, followed by several smaller detonations which shook the big ship from bow to stern.

At Romsey, the squadron was split up into four flights and the pilots were ordered transferred to Royal Air Force Airdromes in England for combat flying training.

On 17 March the non-flying personnel were moved to the Southampton docks and embarked on the Channel boat "Archimdos", leaving about 18:30.

Overnight was spent on the boat and daybreak found the ship in the harbor of Le Havre, Upper Normandy, France.

[3] The officers and men were growing accustomed to the work and surroundings when the German 1918 Spring Offensive began on 21 March.

This necessitated movements and a great deal of work as all Flights were attached to bombing units and three or four raids were being carried out daily.

On the late afternoon of 25, 25 March Sqn, to which Flight "C" was attached, was hurriedly moved back as the Germans were driving on Amiens.

On 25 May 98 Squadron and "A" Flight were moved to the Coudekerque aerodrome, in the outskirts of Dunkirk, however, the enemy bombed the field on the night of 5 June, causing much damage, being considered the worst that any Airdrome experienced.

[3] Additional bombing and strafing attacks with machine guns on roads and troop encampments were made for the next two days as part of the Offensive, and on 15 September a special mission came through for one plane to take off at 10:45.

[citation needed] With the Meuse-Argonne offensive starting on 26 September, more bomber escort missions were undertaken though the end of the month.

[3] The last patrols of the war were carried out on the morning of 10 November when bombing raids was ordered to attack any of these following points: Merge, Meulin, Billy, Seus Magines, St. Laurent, Marville, Quiny, Lamsuilly, Reute, Feucaucourt, Verdun Etain, Maranville, and Feuancourt.

Upon the return of the aircraft that afternoon a great joy spread over the entire field and everyone was out to greet the good news about the pending armistice.

As 11:00, it was announced by the Squadron Commander that flying over enemy territory would cease from that moment on, as the armistice had been signed and the war was over.

[11] Personnel at Colombey were subsequently assigned to the commanding general, services of supply, and ordered to report to a staging camp at Le Mans, France.
