Drownings at Matagorda Bay
A tragedy of mass drownings involving the 69th Indiana occurred at Matagorda Bay, Texas, during preparations for the invasion of Texas.  The regiment was ordered to assemble at Matagorda Island on the Gulf Coast of Texas in preparation for a march north to Tyler.  To move from their inland camp at Indianola on Matagorda Bay to Matagorda Island, it was necessary to cross a 300-yard stretch of the bay using a ferry made up of pontoon boats tied together in a raft.  The raft could carry about three companies at a time.

On Sunday afternoon, March 13, 1864, the regiment began to cross. On the raft's third trip, while carrying companies B, G, and K together with their camp followers, the raft was swamped by a swift incoming tide.  Two officers and 21 enlisted men drowned, with many others carried over a mile away before they could be rescued.

Casualties
The regiment lost a total of 331 men during service; 3 officers and 77 enlisted men killed or mortally wounded, 3 officers and 248 enlisted men died of disease.
