Fort York's powder explosion: magazine or deliberate mine?

Was the Fort York powder store that exploded near assembling troops simply a secondary magazine?

Possibly not; its placement could mean it functioned as a deliberate mine, but the identification remains unsettled.

Powder at Fort York exploded during the War of 1812 near assembling American troops. The location raises the possibility that the site functioned as a mine rather than an ordinary secondary magazine. A large powder store placed where defenders expected attackers to gather could serve as a deliberate demolition even if later descriptions called it a magazine. This remains a tactical hypothesis rather than a settled identification. An ammunition store's administrative label may not describe the purpose its location served in battle.
