When I look at the list of All Texts for ARMAGEDDON, one listed is Forward be our watchward. Obviously a typo, but so far I haven't been able to find it in the database to see if it's correctable.
I corrected all the instances that do not match a scan, but...
This one has the typo on the page: https://hymnary.org/hymn/SoPP1883/293
These have no scan, so had to leave them: https://hymnary.org/hymn/BoP1918/605; https://hymnary.org/hymn/H4B1936/451;
I wish the software allowed for deprecation of obviously incorrect instances in search results.
