Battery No. 2 was taken to Flavy-le-Martel, arriving October 8th. No. 1 remained at Soissons until October 24th, firing in all 199 rounds from the same pit foundation. After the capture of Laon, the target was, on October 2, shifted to a point northeast of that town, where 87 rounds were fired at ranges from 28,000 to 36,660 yards.
Having performed so satisfactorily in the vicinity of Soissons with the Tenth French Army, Batteries No. 1 and No. 2 were ordered to join the First American Army. They arrived at Nixeville, just south of Verdun, October 28th. Batteries 3, 4 and 5, already in that region, had fired several rounds at open fields in the German lines near the targets selected, in order to obtain aviation photographs and correct the range. On the 30th and 31st six rounds per gun were fired each day, the two guns at Thierville firing at an aviation field south of Longuyon and the two batteries at Charny firing at points near Montmedy. Battery No. 2 bombarded the railroad yards at Montmedy with 43 rounds on November 1st and 2nd.
As General Foch was preparing for a big offensive east of Metz, the French requested that two of the naval batteries be assigned to take part in this operation. Accordingly Nos. 1 and 2 were assigned to the French, while the remaining three remained at Thierville and Charny to keep up the bombardment of Montmedy and Longuyon. No. 1 proceeded via Champigneulles, arriving at its firing position, in the forest of Velor, November 6th, its objective being Sarrebourg. Leaving Charny November 3rd, Battery No. 2 reached Moncel-Lunéville, in the forest of Mondon, November 9th, having orders to fire on Bensdorf. Both targets were important German railroad centers. But the signing of the armistice, on the 11th, put an end to the French offensive for which huge preparations had been made.
Battery No. 3, which was shifted from Thierville to No. 2's position at Charny, on November 1, fired at the Longuyon railway yards. No. 4 fired 23 rounds into Montmedy, and No. 5, 44 rounds at the transportation centres of Longuyon. The next day Nos. 3 and 5 each fired 25 rounds at Longuyon and No. 4, 20 rounds at the Montmedy railroad. On account of the enemy's activities at Louppy and Remoiville, No. 4 November 3, fired 25 rounds at a large ammunition dump and at the lower railroad dump at Montmedy. On November 4, Battery No. 4 again took up position at Thierville. No. 3 opened fire on Louppy and Remoiville on the morning of November 4, firing 44 rounds at the two targets. Twelve rounds were also fired at Montmedy.
The naval guns were last fired on November 11th, batteries 4 and 5 sending five shells each into Longuyon. The last shot was fired by No. 4, from Charny, at 10:58:30 a. m., ninety seconds before hostilities ceased.
While direct observations could not be obtained in the Verdun sector, there was evidence from the enemy of the effectiveness of these guns. On November 5, the southern part of Montmedy, which was under bombardment, was reported on fire. Later a German prisoner stated that the firing on Montmedy had caused a great deal of damage, one shell which landed in the railway yards, killing all the Germans in two coaches.
